I have been dealing with diabetes for a number of years and prescribed the same medication. After only one visit with Dr. Trinh, he reviewed my labs and made changes to my medication regimen. My blood sugar was running over 130 and now averaging in the low 90s! I can’t believe it! I feel great! I have more energy and overall feel better. I highly recommend Dr. Trinh to my friends and family!
recommends Mason Park Medical Clinic
Dr. Trinh is so brilliant as a physician and a diagnostician. He is empathetic and is able to understand and care for his patients with compassion. We have been with him at Kelsey-Seybold for over 10 years and as soon as our insurance changed we followed him to his new practice at Mason Park Medical Clinic. It is a small sacrifice to drive an hour to be in his excellent care!
recommends Mason Park Medical Clinic
I’ve been with Dr. Trinh for almost 30 years…And now her brother is taking care of me. Dr. Trinh is a really good doctor too…I enjoy coming here, I really do…All the girls are really friendly, they’re really nice. Y’all need to check it out. This is a really nice clinic.

Dr. Trinh is very knowledgeable, thorough, and patient. He has a good bedside manner, is honest and caring. I have been seeing Dr. Trinh about specific health concerns. He took time to educate me, answer all of my questions, and explain my diagnosis. He put me on a plan that I was able to stick to, and as a result, I have seen significant improvement in just three months!
recommends Mason Park Medical Clinic
Dr. Trinh is a wonderful doctor! He’s very thorough. He takes time to explain things to me to where I don’t have any questions. His treatment plans are based on me and my needs…and they are very effective! He is such a good doctor I have recommended him to my family, friends, and people from my church. It’s amazing to see how many of them he has helped. I tell everyone, if you need a good doctor, go see my doctor… He will help you!

My family and I have been a patient of this clinic for over 25 years and in recent years my health has been declining. After seeing Dr. Quyen Trinh I was finally able to get my blood pressure under control and I have also lost 25 lbs! I am living a healthier lifestyle and I feel much better. Thank you Dr. Trinh for making it a priority to put your patients first!
recommends Mason Park Medical Clinic
I have been a patient of this clinic since the early 1990s and started seeing Dr. Quyen Trinh after he took over the practice from his late sister, Dr. Trang Trinh. I love Dr. Trinh, he changed my medication regimen and is the only doctor that has helped me to get my blood pressure consistently low and well-controlled. He is both personable and caring and that is why my entire family sees him! We love the entire staff and I would highly recommend this clinic!

I’ve had medical problems for the last 20 years. Broke my neck
twice and for the first time after coming to the doctor here, I’ve
felt 100% better…Very thorough, very good doctor.

I think Dr. Trinh is a great doctor…I am happy to listen to his
advice because I trust and value his opinion…I have insurance
that allows me to choose the doctor I want to see. My choice will
always be Dr. Trinh…

Dr. Trinh takes his time to listen to my concerns. I was not feeling well and having a hard time breathing. He ordered an EKG and sent me to see a cardiologist right away who placed a stent in my heart. He literally saved my life! This is why both my husband and I will only see Dr. Trinh, we both trust him with our health. I am so glad that Dr. Trinh has taken over the clinic from his late sister Dr. Trang Trinh!
recommends Mason Park Medical Clinic
Many thanks to Dr. Trinh for fixing a problem I have had for about 20 years!
I had been prescribed many different medications for high blood pressure and none of them had solved the problem.
He was able to fix it in one visit by giving me one medicine in the morning & a different one at night.
Thank you Dr. Trinh for thinking out of the box!!!
recommends Mason Park Medical Clinic
I have been seeing Dr. Trinh now for about two years. He is always pleasant, and places the health of his patients as his top priority. I recommend him highly!

Great experience. Just moved the area, and I’m so glad I found this place. But a lot of places take new patients in Saturday’s and I was so happy when they said they had availability. Everyone was so nice, and Dr. Tran was so nice a professional. He informed me about the problem I was having and he was eager to find the right care to help me. Great place, and location. Thank you all for your help and making me feel welcome as a new patient.
Today I visited Mason Park Clinic, everyone at this office were amazing. They welcome you with a friendly smiles. The receptionist was very kind and personally walked me in. The treatment I received today was fantastic, the technician took her time to explain everything .I was totally pleased with staff and treatment.
Definitely coming back.
Ms. Vanessa is phenomenal provider!! 1st time seeing her and she had a beautiful personality and wonderful bedside manner! Will definitely continue to see her for future appointments!!!
I cannot emphasize enough how wonderful Viviana Escobar is. My primary care doctor referred me to Viviana for muscle spasms. The first visit evaluation was the best evaluation I have ever received. She is personable, knowledgeable and sweet. I am going to refer my family members to her. If you are looking for someone for pain relief give Viviana a try.

I am impressed with my experience at this clinic. Dr. Trinh is great in the way he cares for his patients and he truly listens. The staff is helpful, understanding, and friendly!!!
Dr. Trinh is a brilliant, highly experienced professional family physician who worked at Kelsey Seybold for many years before taking over his late sister’s medical practice. He is sensitive and caring, and committed to providing the highest level of medical care to patients of all ages. I especially appreciate his patience and kindness with my 95-year-old mother. He never rushes his time with her, giving due respect to her concerns and questions. I highly recommend Dr. Trinh as an outstanding doctor.
Dr. Trinh was nothing short of knowledgeable and extremely helpful. His whole staff made me feel welcome and eased my concerns about being sick during these trying times. I would highly recommend going there if you value having a good experience with your health care professionals.
I’ve had nothing but a memorable experience every time I go here. Thank you for your dedication not only to health but to our community. Keep up the good work and giving us the care we deserve!
