Verified Patient Reviews
I would give him more stars if I could! He was knowledgeable, answered all questions, and addressed concerns. The office staff was very nice and pleasant as well.
The medical team is excellent, Dr. Collaco is an excellent physician and the best allergy specialist I have ever met. I received the care I expected. Thank you!
Smart, professional, and knows how to effectively diagnose your ailment!
I really appreciated how quickly the office got me in - for an appointment and back in the room once I arrived at my appointment. Dr. Collaco was nice and knowledgeable. He also didn't make me feel guilty about being nervous (it was my first time at an allergist).
Dr. Collaco takes the time to understand the patient and the symptoms. He is very thorough in a short but efficient visit.
Great staff and doctor who all have a wonderful sense of humour. Made getting the skin prick allergy test feel lile a breeze.
Great attention by doctor and staff!
Dr. Collaco was amazing and his staff were equally amazing. Took time to talk about my concerns, explained things thoroughly, great personality! Highly recommend him for your allergy needs.
Really personable and caring
Awesome staff and Awesome Doctor!
Extremely cavalier approach, didn't read of my chart, or any information from the nurse about my medical history or medications that I take, yet was not necessarily in a hurry. Just practically refusing to use available data for his analysis or recommendations.
Dr. Collaco was very knowledgeable.
Very friendly and listen to what you have to say
Covered everything in an efficient timely manner. Great personality and his nurses/ assistants were excellent. Highly recommend.
He tells it like it is. I feel like we get an accurate assessment and clear instructions on how to manage the treatment. I highly recommend him!
Fantastic! The doctor seemed (and was) really interested and concerned about my lung issues. He spent a lot of time with me. Staff was young and happy and helpful - so glad I made an appointment.
He solved a problem that was extremely multifaceted, and have been misdiagnosed by four other physicians. I am in medical liaison for a very large pharmaceutical company, and speak to physicians every single day. Over the span of 20 years you learn to decern very quickly who is on their game and who is not. This guy is as knowledgeable and as thorough as I have ever seen.
He was very easy to talk to and listened to me regarding my health and concerns. He was very professional and his office staff was great too. I'm glad that I was recommended to see him.
My visit with Dr. Collaco was a perfect check-up. He introduced me to his student assistant Hunter who was very professional. Dr. Collaco kindly filled out some extensive Health Accommodation paperwork for my peanut allergy, and we discussed any problems I have had since my previous check-up. Overall, it was a great visit!
He is fantastic! I'm always reassured after we see him.
Dr. Collaco is very friendly and professional. Dr Collaco took time to make sure he understand our symptoms. He was very thorough and he explained everything. He even found other medical issues beyond allergy. He worked with us on our budget for medication.
I really like Dr C. Not only has he helped me manage my allergies, he is also quite personable and knows his stuff!
Professional and Personable.
Very thorough, very caring doctor. Wants to know as much about you in order to provide you adequate care.
Excellent Doctor. Spends plenty of time with you and gives realistic and actionable interventions. My daughter sees him too.
I was hesitant on going since it's not close to where I live but this place had the highest reviews. My doctor wanted me to see an allergist since she told me I had asthma and this was news for me since I have never been told that. He was very direct and to the point with me which I love because I felt he knew what he was talking about. Parking was easy and it was not crowded. The test were annoying but necessary. I do feel confident in having him getting whatever is wrong with me under control.
Great doctor, very knowledgable and always on time. Highly recommend.
Very comprehensive and no waiting around. Very impressed
Love, love him! He has a great bedside manner, very knowledgeable and funny. He doesn't rush the appointment, really tries to figure out what is wrong and fix it. People in the office are nice as well- which is a hard find these days. ~SMS, Bellaire
Very efficient office. I was brought back right away. Dr. Collaco was very informative and answered all of my questions and was very helpful. All of his office staff from the front to the back that I encountered today was very friendly. I was happy to find something close to home as well!
Very compassionate, knowledgeable, and skilled physician. professional, friendly staff. I was very impressed and delighted that I selected his practice.
Went there and stated specifically that I'm allergic to cats and dogs and that I was interested in allergy shots, went through an allergy test to be told "hey you are allergic to cats and dogs, your options are to stay away from them, allergy pills or shots". Mentioned again that I was interested in shots, and then was told "Well if you are interested in shots we will need to do a full allergy test instead of just the cats and dogs".... Waste of time.
All in all very good visit. Doctor is extremely knowledgeable!
Took my daughter to see this doctor. He was incredibly pompous and condescending. I would NEVER recommend him to anyone and regret we went in the first place. The only saving grace was the staff.
Finally relief! After seeing 4 different doctors and being sick for 2 weeks, Dr. Callaco diagnosted my problem quickly and accurately. I cannot thank him and his very kind staff for their help.
Excellent service and very professional. As a nurse working around doctors every day, it's very refreshing to have a doctor that is 100% realistic, straight forward, but also caring and compassionate. Dr. Collaco took time to listen to why I was making the visit and he went step by step on what was going on with my situation and the different options I had. I appreciated the amount of time he spent with me to discuss everything, even though I'm also a healthcare professional. Would definitely recommend to anyone!
Dr Collaco and his staff are very attentive, listen to the patient's concerns and are prompt in the attention and prescriptions to promote wellness. I highly recommend Dr Collaco for his expertise and general concern for the patient.
Always right on time and very efficient. Great doctor-highly recommend
I booked my appointment thru zocdoc. When i checked in they said they did not receive request for the appointment. But she took me anyway which was good. But the wait time for the doctor to see me was more than 45 mins. I guess busy day! Overall experience was good and would recommend it.
So far it is good, I will add more after follow up visit in a few days
Dr. C was very professional and explained things well to my 7-year-old son. We were seen very quickly, and his staff was very friendly.
Dr. Collaco was very professional and thorough in how he approached my treatment. He was honest with me about when certain testing needed to be conducted and even stated that he did not want to complete tests I did not need because he did not want to charge me for them. I appreciated that a lot!
Dr. Collaco was very thorough, tremendously courteous and helpful. He took the time to explain things to me so I understood and also took the time to understand what I was going through.
First time visit. Dr. C and his staff are great! Check in is quick and painless. Dr. C made sure that I received a complete assessment for my allergies and explained my treatment very thoroughly.
Has very patience and talks about your problems, more importantly explains you how could this be resolved. Very nice Staff too.
Has helped me out immensely by quickly identifying and treating a new allergy. I now am on a shot regimen and my condition has improved significantly compared to when I first saw him.
Super knowledgeable, warm & friendly, funny, very good bedside manners, and listens to concerns and provides answers.
Overall i was very satisfied. He was very warm, friendly and the wait time was like a few minutes.
I think Dr. C is so amazing, best doctor I've ever been to. He really listens to your case, including other medical conditions that other specialists always seem to ignore since it's not in their area. Highly highly recommend.
Fill out everything online and have medical history ready.
Very professional and caring doctor and staff.
He is very professional and friendly. I would recommend to anybody looking for resolution to their allergy problems.
He was very personable, informative and attentive. I was given many free samples to limit my expense for prescribed drugs and was also made aware of any procedures that would be extra cost multiple times. One other positive thing is that when I had a concern about something unrelated to asthma, he gave me a card for another specialist that he has confidence in. I felt comfortable and we'll taken care of by the whole staff.
Excellent Doctor. Dr. Collaco spent a great deal of time helping me with my sinus issues.
He was nice, good listener, asked a lot of questions and patient. Treated me for sinus infection. He performed the infection test right there and I didn't have to wait too long for the results. I will be back for allergy treatment after sinus infection is gone. New and nice office space.
Dr. Collaco was very friendly and professional. He was very good about working with me and finding the best possible treatment. His staff was very nice and personable and easy to work with. The clinic was very easy to find and parking was a breeze. I would recommend this office to anyone!
Very professional and helpful doctor, and with nice attitude! Thank you so much!
Excellent experience! Office staff were friendly and efficient. The doctor was professional, informative and friendly. I would highly recommend this office to friends and family. It was a genuine pleasure.
Friendly staff and Dr. Collaco was very informative and thorough. I appreciate that he educated me along the way.
Dr. Collaco is a great doctor. He has breat bedside manner. He has helped me tremendously to reduce the effects of my allergies. I have more energy and fell better with his recommended treatment. He calls or emails in prescriptions, making it a lot easier to get the medicine. Especially with Express Scrips.
I started having allergies about 5 years ago. I was getting sinus infections in in the Fall and Spring. Dr. Collaco successfully treated all my allergy problems. I'm currently taking allergy shots which have significantly diminished my allergy problems. It's easy to make appointments and Dr. Collaco and his staff are wonderful. I recommend Dr. Collaco to any adult or child suffering from allergies or asthma.
This was my first visit. Fast, informative. He seems like a nice doctor.
He was knowledgable and thoughtful about the procedures he performed and was very patient with my two other children that I had to bring along to the appointment.
He does not rush through appointments. I have always found him to be quite detailed in exams and the diagnosis process. His combination of skill in diagnosis and warm demeanor is very rare.
Great allergy doc.
Very professional staff and no wait time. I had my appointment at 2pm and we were called right away. I highly reccomend this dr. He is very knowledgeable in his field and helpful with fully explaining any questions you may have.
He was kind and attentive. I would recommend him to anyone.
The office was very clean, the staff was extremely nice and Dr. Collaco's bedside manner was perfect. Another good find on ZocDoc! Two thumbs up!
Dr. Collaco really took the time to listen to me to try to determine the best course of action to address my allergy issues. It was an enjoyable doctor's visit when I physically felt lousy. I would and will definitely recommend him to others.
Very positive experience.
I was very pleased with this doctor. He spent a lot of time answering all my questions, there was zero waiting time, and he inspired a lot of confidence as a medical professional. I highly recommend him.
I have used Dr. Collaco for many years. He has always taken great care of me as has his entire staff! I would highly recommend this highly professional and caring office.
He is very personable, thorough, and gave a variety of remedies.
I saw Dr. Collaco to determine if I had a particular allergy. Very thorough in his questioning and in his subsequent explanations for what might be ailing me. I found him to be personable and caring. I'd recommend him to family/friends.
Conscientious and thorough; quite knowledgeable and proceeds systematically to arrive at diagnosis
I have been suffering from allergies for 7 years. The professional treatment I received in Dr. Collaco’s office improved my health condition caused by allergy right away. I am very grateful for that and appreciate Dr. Collaco's expertise. Tatiana Sheiko
I'm the type of person who does not enjoy visiting a doctor. I've had enough bad experiences where the doctor seemed more concerned about their paycheck and doing the minimal work necessary, while leaving the patients to deal mostly with assistants. Dr. Collaco is NOT that doctor. I've had three visits with him now and all three visits were superb. Appointments have been on-time, maybe with a few minutes wait at most. An assistant will check your blood pressure and weight as well as record your initial reasons for visiting, medications being taken, etc. But once that is done, you are dealing with Dr. Collaco for most of the visit. Dr. Collaco is a very patient doctor and definitely is knowledgeable in his field. He listens very carefully and discusses your conditions very well. Most of all, he definitely does not up-sell anything and is conscious of costs when it comes to medications and follow-ups. What really solidifies my 5-star review is that when I went to the pharmacy later the same day of my visit to pick-up a prescription that he sent electronically, the pharmacy claimed to have not gotten it. I called the doctor's office right around lunchtime, not realizing the office staff was on break. Dr. Collaco himself answered the phone and once I explained the situation, he told me he would look into it immediately. He called me back a few minutes later to tell me that he had called the pharmacy and after a little prodding they were "oh, yes we do have the prescription here!". It was definitely above and beyond for Dr. Collaco to personally take care of the situation during his lunch break. He is a rare doctor to do that and I couldn't recommend him any more after that experience.
He is a best doctor I ever seen
Dr. Collaco is very caring. He is responsive. He listens and doesn't just jump in there. He is thoughtful and kind. When I go to other doctors, I feel as if they make it a point to let me know they are a doctor and that I can't possible know what is wrong with me. Not Collaco, he asks questions and really tries to understand your symptoms so that his treatment is appropriate and doesnt just throw a prescription at you. He is thoughtful about his medication selection. I have only seen him twice, but the times I have visited with him, I have been really impressed with the service he provides. He seems to genuinely care about people.
I went in with severe seasonal allergies. Dr. Collaco listened to what I had to say, tested, diagnosed me and set up a plan to make me well. He is a straight shooter and you can tell that he cares about his patients. Two days later and I am breathing much easier. I recommended him to my manager who is suffering with allergies as well.
Dr. Collaco is very straightforward and direct which I really liked. I also like that he took the time to get a full history of my son and was willing to look at the big picture with his health issues.
Wonderful Physician who truly cares about his patients.
