Verified Patient Reviews
I was very uncomfortable with the office staff and their extremely cold demeanor. As a new patient I did not feel welcome or properly taken care of considering I was newly pregnant and battling the flu.
Dr. Green Jean was professional fast and knowledgeable
Dr. Grandjean and his staff are great!
Well mannered and thorough.
Dr Grandjean was more interested in writing notes and not talking to me about my past medical history, or what was going on with me currently.
Very professional, very nice and kind. All the office staff were very nice and helpful!
Dr. Grandjean has excellent bedside manner and his entire staff is so caring and professional! Highly recommend this office!
Dr. Grandjean and his entire staff are amazing!
Very professional, understanding doctor. Appears he'll work with patient instead of being demanding! So far, so good!
He is a very caring doctor,who wants to get to the root of your problem. I had him as a doctor in the past and due to location transfer had to go with another physician. Awesome doctor.
Fantastic doctor and wonderful staff! So knowledge and friendly. Highly recommend!
The whole experience was wonderful. I feel very safe and cared for by the whole team.
I was surprised when I went in that this was a family medical center and not a dermatology office (as I searched/filtered ZocDoc for Dermatology Specialists). That's not the office's "fault", but it's good to know... I was helped immediately and after filling in paperwork for about an hour (since it was a general practice and not just questions about skincare and history), I was called in immediately to be prepped for the doctor who I also got to see almost immediately after being admitted. He was kind, had great bedside manner, read through and asked me questions about my paperwork (even though I was only there for an acne check-up), and found off-brand substitute prescriptions for my acne and eczema pills and ointments. I would recommend Dr. Grandjean.
Pays attention to all details. Very professional. Always a pleasure to see when needed. Thanks Doc.
Very professional! Staff is friendly and attentive!
I really like the receptionist ,nurse and Dr Richard Grandjean. Feel very comfortable going to this office . There is never a full office when I get there. No wait time!!!??
My visit with the doctor was a good one.
Very nice visit. Outstanding staff assisted with all insurance questions! Thanks!
My previous doctor retired. This was my initial visit with Dr. Grandjean. All the "first visit" paperwork was painful, but understandable. All the staff and doctor were very helpful and professional. I believe I made the right decision with my choice.
It was relaxed show how folks care it is better than most I have been too and it is straight to the point Thank you.
Dr. Grandjean has been our family doctor for 2+ years now and we are 100% satisfied with his interpersonal and professional skills.
My mother enjoys meeting Dr. Grandjean and loves having him as her physician. She had gone through a number primary care physicians and is very happy with him. She wants to stay with him from now on. My only complain is that I had filled out all of the required paperworks and sent the information ahead of the appointment time to the office thinking that it would be easier for my mother. Somehow, the office kept asking the same question again even though all of the paperworks have been sent ahead of time. Their explanation is that they are very busy and don't have the time to print out the completed forms. I would ask that going forward, please check the completed information.
One of the best family doctors i have ever been to. He is efficient and thorough. I actually look forward to my appointments now.
It was a good initial visit. He was nice and easy to talk to.
He was very interested and was wonderful. Like doctors should be. Talked to me didn't just look at the computer. Highly recommend.
Always take care of my issues
Excellent, professional care. Genuinely concerned about my health.
Awesome doctor, and I want him to be my primary doctor even though I live here in oklahoma, I don't miND driving 59 miles.
My visit with Dr. Richard was great! It was my first visit so i didnt give a 5 star, but i will comtinue to go to him. He listened to how I was feeling and gave me info on my problem. That was great!!! The other staff was nice could have used more smiles,but thats was ok. Oh and Dr.Richard didnt rush me out of his office!!!
I am very pleased with Dr. Richard Grandjean, he takes the time to listen to all of my complaints, he's very thorough when analyzing my problems and he provides helpful recommdations/solutions. His staff is professional, friendly and very helpful.
Just got back and couldn't get to my computer fast enough. Total waste of time. He needs to begin with finding new personnel. Receptionist has the personality of a pen. The "bedside manners" rating is directed towards his staff which did not make you feel welcome, but more so made you feel as if you are bothering them by coming in. They (including Dr.) refuse to review your current medical file from another Dr. and results from 2 weeks prior before arriving because in their minds it makes more sense to waste your time in coming back. Don't waste your time! You will feel like you are in the Walmart of doctor's offices in regards to quality.
Dr. Grandjean was great! I was seen within 10 minutes and he went right to testing my knee for any structual damage.
Dr. Grandjean is very kind and listens to you. I fully enjoy every visit I have with him.
Addressed my circumstance professionally
I wasn't really to excited about seeing a male doctor being a woman and never having one before to begin with. I've always preferred female docs but based on his location and reviews I decided to schedule. First off, there was no wait at all. Wonderful! The new patient intake was easy and fast! Staff was friendly and the doctor was incredibly informative. I've seen lady docs that don't have as great a bedside manner as him! Definitely would recommend and plan to keep my long term health under his care! Already made my next appointment! Thanks Dr. G!!
Dr. Grandjean and his staff are great. They always get me in out and out and treat me great.
very professional and quick accurate decisions
Very thorough and very nice! I will continue going to him and will take my son to him as well.
Very nice man. Best doctor I have seen since being in Texas.
Very thorough, polite, knowledgeable, and professional.
Outstanding physician with years of experience.
Prompt professional service. Explained everything I wanted to know.
Very professional and an excellent listener. Extremely thorough and efficient.
Great doctor! Thanks for all your professionalism Dr. Grandjean.
I appreciated Dr. Grandjean's professionalism and concern. However, his office staff was less than professional. At one point, when the phone had rung TWICE, I heard one of the receptionists/office managers state, "I can't believe this! I've got WORK to do!!"
He listened! I was impressed with every person I came in contact with,at this office. A plus
Dr. Grandjean was great! He took the time to explain everything. He is a very patient centered doctor!!
I was a new patient and was able to get in right away. Staff was very polite and helpful. Dr Grandjean was great. He listened to everything I had to say, did my exam, and treated me all on the same day. No need to do a new patient appointment then come back for another appointment for treatment like I have had to do at other places. He addressed all my issues the first time.
Checked out my knee and gave the good news all I needed was over the counter inflammatories. Plus he wanted me to schedule my annual physical. Top notch.
Been a long time I've been to the doctor, but Dr. Grandjean was much better than what I've come to expect. I waited about 20-30 minutes, which I didn't mind, but he apologized profusely. Great guy overall. Would definitely recommend.
I was actually seen before my appointed time. How rare is that?!
THIS WAS MY FIRST VISIT, AND HE LISTENED TO EVERYTHING THAT I HAD TO SAY. HE UNDERSTOOD MILITARY LANGUAGE AND WHERE I WAS FROM.
The doctor was great but the staff is terrible. The front desk crew not polite at all.
He's a great doctor and I am on my way to recovery as always. Been my doctor for many years.
I've never seen my 3 year old adapt so well with a doctor he actually let him exam him no crying or anything. I enjoyed it. Gave me some good articles on some concerns I had with my child.
Dr. Grandjean was outstanding. He was extremely courteous, understanding and professional. He made me feel at ease and gave my problem the full attention it deserved. He prescribed medication which I am sure will deal with my medical condition.
It was not that informative. I like for my doctor to sit down with me an explain the diagnoses and what factors came together to give the diagnoses. I don't like to go to the doctor just to get a prescription. I would've like preventative factors that I could possibly implement to be more healthy.
Very quick and courteous staff. Nice office and electronic sign in was a breeze.
The best medical care anyone could ask for!!!
A nice experience
Dr. Grandjean is very thorough and knowledgeable. He took the time to read through my paperwork, ask questions and listen to all of my concerns. I am very comfortable with the diagnosis, medications and action plan. Everything about my appointment was excellent! Dr. Grandjean and his staff are a great team!
Very informative and helpful
Favorite physician to date.
Great doctor. Great staff! Friendly, helpful, and professional. Did not feel rushed. The Dr took time to hear all of my questions and provide important information.
Fantastic Dr and staff. Dr. Grandjean is at the top in his profession. He and his staff treat you like famility from the first appointment reminder to the follow up.

Dr Grandjeans is a doctor that truly care about his clients and their needs
Very attentive, as always. Solutions always offered.
He has great bedside manners. He take the time to explain everything to u. He's great
This was a preliminary appointment. It's been great so far, but it's still too early to tell.
He is very polite, cares about your issues and is extremely informative in what he does.
The Dr is always attentive to my concerns.
I felt that the staff was very unfriendly everyone from the receptionist and nurse. The doctor was ok but seemed he didn't really care about my health or issues I came to see him for. Maybe he was having bad day but first time they didn't even check my blood pressure which I listed as issue. I would not recommend him to friends or family
So far he seems like a great doctor, I feel that he will help me with my problem.
Dr. Grandjean is a great doctor. They also have a great office staff.
He took the time to listen and asked appropriate questions
Extremely professional! Made my appointment the day before and had no wait to see the Doc.
Dr Grandjean was wonderful. He really took the time to evaluate my daughter's symptoms, and talk about causes and treatments for her. My daughter does NOT like going to the doctor but she was very calm with him. His bedside manners are wonderful! We will definitely use him for now on.
I liked that he was concerned with what was going on with me. I also liked that he wasn't a doctor that rushed just to get you out of the office.
Outstanding professional,fine man.
Always smooth and effecient.
It was very informative and professional. I can always rely on Dr. Grandjean.
Dr. Grandjean is well organized, affable and very competent. He cares about his client/patients.
Very nice and thorough
Very professional. Office staff answered my questions about the visit with the doctor. Dr. Grandjean was even able to address two issues for which I was going to request referrals to a specialist.
