Verified Patient Reviews
Dr. Theriault was amazing! I have been to a ton of very unhelpful, impersonal doctors so I was a bit skeptical at first. But Dr. Theriault was very personable and friendly, and I could tell that she genuinely wanted to take the time to discuss all of my concerns. I was very pleased with my visit and plan on seeing her long-term.
GREAT experience with the doc but wait time was a little bit annoying.
I loved Dr. Theriault! Very nice and was clear and professional.
Doctor T is great. Professional, knowledgable and personable.
De. Theriault is great. She took the time to look at my moles and explained things to me. She recommend only products that I really need.
Dr. Theriault is awesome. Just the best. I've been going to her for years and can't imagine going anywhere else. I would highly recommend her in an instant.
Dr. Theriault is very warm and friendly. You feel like you can tell her anything, which is really nice. She is also thorough and it never feels like she’s rushing you. I would highly recommend her. The wait time for appointments can be long sometimes, but it’s probably because she takes the time to help patients as much as she can before they leave.
The doctor and staff were professional and friendly. I was very pleased with my visit.
She was awesome, super attentive and very fast. Thanks!
Dr. Theriault is fantastic!
I think Dr. Theriault is very good at her job. I have complete confidence in her diagnosis and trust her knowledge. Overall, she is a great and trusted doctor. My only complaint is that I am always rushed in my appointments. Almost every appointment I have had, the door is already open by the nurse before I am even done talking because they are in such a hurry to leave the room. I never get asked "anything else?". Instead, I have to ask them to shut the door in order for me to finish addressing my concerns. Specialty doctor copays are expensive and it's hard to get appointments. I deserve more time and attention in my appointments. Please don't rush me!
She’s awesome and super personable!
Dr Theriault is awesome! Professional, friendly. Exceptionally doctor/patient communicator.
Very thorough but also fast. Super nice, too! Thank you so much!
Everyone in this office was friendly, helpful, and efficient. They listen!
Always a positive experience and fun to catch up with her. She and her team and attentive and thorough. Love Apex!
Quick, informative. to the point, by kind of doc!
As ever, Dr. Theriault always knows what to do and gives you options for your care. She is so very friendly and a terrific physician. She has been my dermatologist for about as many years she has been in practice and I have been fortunate to have her as my physician. Susan H.
She's very professional and sweet.
She is always thorough and very nice. Highly recommend her.
Dr. Theriault was very friendly, empathetic and professional during my appointment. She spent enough time to get sufficient information to make a diagnosis and had me in and out in quickly. I appreciate that since I had taken my lunch break to see her.
She makes me feel like she has all the time in the world to discuss any issues. She's amazing.
I love Dr. Theriault, but everytime I come for an appointment, I'm not seen until 30+ minutes after my appointment time. This can be very frustrating :(
This was my first visit to this office. I found Dr. Theriault to be very friendly, knowledgeable and thorough even in a short appointment. I felt the staff were attentive - although the front desk was a little slow. I would recommend this office and I am happy that I found a dermatologist that I can see for regular visits.
Very nice lady. She is very thorough. I have been seeing her for many years.
Dr is great. Waiting time is ridiculous
Love Alex and her services. The 30+ minute wait, I could do without.
I had to wait more than an hour to see Dr. Theriault. She is the best but on a morning that I have to get to work, this is too long to wait. Front office seems very disorganized every time I am there
Dr. T is always detailed in her exam and inquiries..She provides solid treatment with efficiency and good cheer..Always a pleasure to see her.After my appointment, I feel fortunate to be in her care.. Bill H
She is friendly and so nice. I love seeing her. She makes me feel like she really cares.
Professional, personable, caring, willing to listen. A+++
Dr. Theriault is always so friendly to me. She's very professional but she also takes the time to ask about your personal life and how you are doing.
She is awesome. We have been with the practice for years, and love it!
It's always a pleasure to see Dr. Theriault as she's been my dermatologist for a number of years. Dr. Theriault is very professional, courteous,and welcoming. I highly recommend going to see Dr. Theriault if your in need of an excellent dermatologist.
I love Dr. Theriault and make my annual apt 6 months out. Very disappointed that I had to wait an hour and 10 minutes and than be rushed through my appt. I work in the medical field and completely understand how a schedule can run behind, but an hour and ten minutes wait is not acceptable. Your patients time of taking off work, paying high Specialist Co-pays , etc. should be valued as well.
The services I receive from Dr. Theriault are great, and she is a joy to see, but the wait times are unacceptable. The last two times I have been there I have waited an hour to be seen for a botox treatment that should take no more than 10 minutes. I am very disappointment on that side of the service at Apex dermatology!
Waited 35 min to see her. She was in the room w/me for 5 min, I felt she rushed a lot, but she was nice.
Dr. Theriault is awesome! Love her. She has excellent bedside manner and is sooo knowledgable.
Great as usual??
Dr. Theriault is awesome! Personable and thorough. If I am unable to schedule an appointment right away at her Littleton office, I will drive thirty-five minutes just to see her at the Lowry office.
Very personable. Not rushed and very open to my concerns. My wife is very happy with her as her doctor too.
As always, visit was excellent, except for the wait time.
Dr. Theriault and her staff are excellent! Answered all of my questions respectfully & helped me address issues previous physicians could not.
Dr. Theriault is one of the most caring, attentive medical providers I have ever consulted. She listens carefully to any concerns you bring to her. She is very detailed oriented, thorough and careful in her examinations. I have been a patient of Dr. Theriault's for ten years. Whenever she identifies a concern, she puts it into context and works to address it. She makes sure to provide sufficient information so that her patients feel confident in her diagnosis and proposed course of treatment. It is rare to be kept waiting in her office, but when I am, I do not mind, because I know she is giving the level of care to others that I've grown to expect and value from her. I have recommended her without reservation to anyone seeking a dermatologist, even those who do not reside in south Denver.
I have seen Alexandra for many years and value her excellent medical skills.
Dr. Theriault is the most amazing Doctor EVER!!! I cannot say enough great things about her, I recommend her to everyone, I have had multiple issues with my skin which resulted in many stitches and you can hardly see the scares. If she ever changes career she would make a heck of a tailor. All joking aside she is truly a good person and great doctor!!!
Not only beautiful but very professional and caring. I could not ask to be in better hands.
Dr. Theriault was recommended to me by my Family Physician. I am glad I made an appointment and my experience was great. Thank you.
It is absurd that patients have to wait 45 min. past their appointment time for a morning appointment.
Great Doctor!! I been with her for years and now my daughter turn, she's awesome Doctor!! Love her professionalism!!
She was very thorough and very personable. I would definitely recommend her.
Dr. Theriault was so positive and thorough I felt at ease with my concerns. The whole staff at her office was efficient and super polite. Definitely recommending her to anyone!
Dr. Theriault and her staff makes you feel at ease from the moment you walk in the door.
It's always a pleasure to visit Dr. T, she is up beat, professional, and simply a good person.
Dr. Theriault did a great job, she was very informative and helpful. Great experience.
Dr. Theriault was very personable and made me feel she listened while making best use of both of our time. She communicates well. Also really enjoyed her MA.
Knowledgable, professional, engaged listener, warm and pleasant
I'm a Mom of medically fragile young adults and have spent 23 years living in waiting rooms and hospitals. I know docs. I am very very happy w/ Dt Therioux and her whole office. They work hard and succeed at making you welcome, it runs smoothly, and you feel like she really has given you time and her expertise. I've had 3 significant proceeds in her office and the follow up and access to info has been great! There will always be some delays, as she takes time with complicated issues as needed. It's worth it.
Dr. Alexandra Theriault is a very personable doctor and I had all the confidence she knew what she was doing. I will recommend her to family and friends.
Pleasant personality, explained procedure to me I like her..I will return
Great doctor. Great staff. Super nice office. Easy to park.
Dr. Theriault was extremely professional yet relaxed, and very thorough and knowledgeable. She is a good listener, looking to get the patient's input before rushing to a diagnosis. I found her approach very refreshing and unusual. I will definitely recommend her to others looking for a dermatologist.
Great visit, she quickly diagnosed the issue and removed it in less than 30 min, super sweet staff as well.
What bedside manner?
Awesome! Love her and the staff. Highly recommend for whole family.
Love Dr T. Very professional and very reassuring. I was a bit nervous prior to visit (brought my husband along for support) Dr T put us both at ease immediately.
I was very satisfied
Very personable, yet professional. Great comfortable atmosphere in the office.
Exceptional MD who listened to my concerns. Bed side mannner exceptional, I would definitely recommend. Warm and inviting office !!!!
Waited in the lobby for 30 minutes, then was taken back to exam room to wait for another 35. Nurse (clinical assistant) who took basic info was lack lustre and impersonal. Dr. Theriault was sweet, but extremely rushed. I had driven 45 minutes to the office, to wait over an hour, to be given 7 minutes of her time. Not a good feeling.
She is by far my favorite Dr. Great energy and she always makes me feel important.
She is very professional and very caring. I feel like I am in good hands and can trust her opinions.
Dr. T is AWESOME. Fantastic support staff from the front desk to the nurses that assist in procedures.
Dr. Theriault was great! She answered all my questions and made me feel very comfortable.
i always enjoy seeing Dr. "T." She's so upbeat and pleasant. Can't say that about most other Dr's.
There were two of us for a double appointment. We were asked to come thirty minutes before the first time. We were not taken back until about 45 minutes after we got there. Seems like the 30 minutes was too long.
I was very pleased with the staff as well as the doctor. The wait time was a little long, but I understand that is sometimes unavoidable.
Dr. Theriault provides excellent personalized attention. Support staff is also very accommodating and friendly.
I love Dr. Theriault. She is one of the friendliest docs. out there. She knows her stuff and takes the time to discuss concerns and determine a treatment plan that is individually appropriate. I would highly recommend her!
The office staff is friendly and courteous to answer questions. The whole process with the staff and Doctor is terrific. Questions answered and very thorough on the exam.
Visit was fun speedy. Dr T gave me some options and we went right to work and finished in a hurry. Her beside manner is always great, professional but fun.
Dr. Theriault was friendly and efficient but she just kind of came in, shook my hand and started looking at all of my freckles and moles. There wasn't any transition from hello, nice to meet you to the clinical care which made it a bit awkward. I was actually almost ready to leave as she came into the exam room, as I had been waiting for 35 minutes to be seen. In my mind, this is completely unacceptable. I at least would have expected someone to pop in to give me an update on the wait time so I knew what to expect. My visit was a bit frustrating to say the least and I'm not sure I'll be back.
I appreciate Dr. Theriault's thoroughness during my annual examination. She is very personable, humorous, and makes you feel comfortable in the office. I'd recommend Dr. Theriault without hesitation to family and friends.
She is wonderful !!!! I brought my family member in we do not have ins and they were very reasonable with the self pay charges! I am going to see her soon myself ! I highly recommend
She is very professional. Has a warm personality and put me at ease immediately . Diagnosis and treatment was fast and easy. Of course I would go to her again
The office staff including the doctor's assistant were extremely professional, upbeat, and friendly. I expected a long wait after reading other reviews but that was just the opposite of what I experienced. I checked in, completed paperwork and within 5-7 minutes was in an exam room. Spoke to assistant for a few questions and the doctor came in right afterward.
Dr. T is the best! She is very friendly, easy to talk to, professional and just a pleasure to work with on all of my needs and always answers all of my questions in full understandable terms.
Dr. Theriault is a great dermatologist
Answered my questions and took a good look for anything suspicious. Gave me different options for treatment. Very personable doc and helpful staff.
I was made to feel comfortable even when faced with a potentially serious diagnosis.
A great doctor with a charming beside manner. In fact, her assistant, Deb is wonderful as well. Thanks!
She really helped me to understand my condition and how to protect my health in the future.
Dr. Theriault was very thorough and allowed plenty of time for me to raise my concerns and for her to either treat them,give a full explanation about those concerns, or propose future procedure or treatment options. The doctor and the entire staff were welcoming and friendly.
Perfect as always. She is always pleasant and upbeat which is refreshing.
Dr The rialto is great! She and her staff are professional and fun at the smell time. I trust her and she always spends time on a personal level as well
Alexandra was fantastic! I really appreciated how comfortable she made me feel; she is very nice and friendly. Alexandra was on time, quick with my appointment, and just a lovely person. I would highly recommend her.
Great, quick service and did not have to wait 2 or 3 months for an appt.
Love seeing Alex - I trust her approach and treatment completely. The only drawback to seeing her is the extended wait time. I waited over 40 minutes from appointment time until I saw her. If I did that to one of my clients, they would fire me. That wait is not acceptable.
Very personable and knowledgeable. She displayed a great amount of compassion. She was very confident in her assessment and diagnosis. I don't know as of yet but I'm hoping she's spot-on and I feel better soon.
Dr. Theriault was very personable. I was there today to get a yearly head to toe skin check. She was very thorough in my exam.
I love Dr Alexandra. I have been going to her since she started her practice. She is very thorough and friendly. I always e Recommend her to friends. H. E.
The wait time was very short, assistant was courteous and helpful. She took appropriate information. Dr. T. came in a short time and as usual was very nice-then went on to check skin areas for signs of problems and did freeze three areas on my face and ear. Overall I was very satisfied with my visit and Dr.T advised to make an appt. in six months.
Very informative, easy visit.
Excellent, professional service. She rocks!
Dr. Theriault is always SO kind, genuine, helpful with information and always listens to my questions and concerns while being very thorough as well as time efficient. I've been seeing her for nearly 10 years now and wouldn't go anywhere else.
After waiting more than an hour for our appointment. Dr. Theriault spent about 3 minutes in the exam room with us. The majority of the time was spent gushing over her new assistant. She barely spoke to me or my daughter but spent more time talking to the assistant and the nurse. She was then gone before we knew the appointment was over. When I expressed surprise, the nurse offered to answer any additional questions or, if I had complaints, she could have me talk to human resources. What?!
She did a great job, understood my problem and was very helpful.
Alexandra was very patient, professional, and informative. She listens to your concerns and cares to help you in any way she can. My experience with my last few visits have been exceptional and I would highly recommend her to anyone!
Dr. Theriault was so nice, friendly and professional. She was very clear about my medical issues and very thorough. I would definitely come back for an appointment if needed and refer her to my friends.
Dr. Theriault has been the best. She is caring, her staff professional. I have had quite a few things over the last 16 months and she has taken such good care of me. I tell everyone to go to her.
Excellent, she really knows her skin stuff. Very discriptive in what she sees while examining you. She clearly identifies issues of concern and why. Doesn't waste time, but still doesn't rush you out.
Dr. Theriault was great and the staff was really pleasant. I would have no apprehension of returning for treatment and would quickly recommend Dr. Theriault to a friend needing her expertise.
she was personable and thorough, and was the first derm to take a biopsy of a skin condition that's been going on for over a year now instead of just writing a prescription.
Dr Theriault and her team saw me shortly after my appointment time and had me out in time to make my morning meeting at the office. Shortest wait time for a specialist that I've ever experienced. My needs weren't very complicated but she took the time to really talk through the family history, treatment options, and chart a course of care into the future.
She was wonderful, friendly and professional.
Dr. Theriault was so friendly and really helped me come up with a treatment regimen for my skin issues. She answered all questions. She was very personable and made me feel completely at ease.
She is the BEST!
Very difficult to reach some one on the landline for this location.
Was pleased with the entire staff. Will be returning for further treatments. Very professional and friendly office.
The Good: I was greeted warmly upon arriving for my first visit. They use an iPad-like electronic system for filling out initial paperwork, which I was able to take with me to the exam room and finish completing - it was easy and green! I was called within 5-10 minutes of arriving. Dr. Theriault was extremely friendly and approachable. The Bad: First of all, I DID arrive 5 minutes late. However, despite being called back quickly, I waited about 30 min in the exam room, and then when the doctor did come in, it felt very rushed. This was my first time seeing her, and I felt like she quickly told me to try a certain medication and I left thinking of many questions I would have liked to have asked her, but in the flurry of the appointment, hadn't thought of.
My first visit with her, and it went really well. I thought she and her assistant were very helpful and personable and made me feel welcome. The woman at the front desk was also great. My only complaint was the wait time was a little long (maybe about 30-40 minutes between the time I walked in and time I actually saw the doctor), but I suppose that's not all that excessive for a doctor's office these days.
It was fast and fantastic. She greeted me, remembered our last appointment, discussed and addresses my concerns.
Truly the utmost in professionalism.
This was a new patient visit. I had no wait time which was awesome. I loved Dr Theriault. She seemed extremely knowledgeable and her bedside manner was great. I would recommend her to my friends.
The entire staff was professional and polite. Dr. Theriault was professional, answered all questions, she explained each process and steps fully.
Excellent- the nurse was very good as was the Doc!
She is very good at what she does! She examines you while carrying on a conversation which makes it much more comfortable! She' a great doctor and I refer to her often!
She was very kind and gentle. I was nervous and she made me feel at ease. She's awesome :)
Very personable, and professional! Highly recommend!
