Doctor Osayande listened carefully and asked appropriate questions. She is compassionate and kind.
I had a great visit with my doctor, very professional and informative five stars
I had a most awesome first-time visit with Dr. Osayande. She went over many questions and provided answers when appropriate. She was thorough and knowledgeable about GI issues, which is her specialty. She explained everything in detail and assured me during my visit.
The staff and nurses are friendly and courteous as well. It is a good idea to fill out all paperwork prior to your first visit. She accepts new patients and is truly a doctor who listens to you.
I am glad I got an appointment the next day due to a cancelation.
Thank you

I cannot say enough great things about Dr. Maryann Osayande (Dr. O)—she is truly a lifesaver! 🙌
For the past seven months, I had been dealing with brutal heartburn—to the point where I couldn’t sleep at night. Like many people, I made the mistake of consulting Dr. Google (which I do not recommend), and I became terrified—reading about everything from esophageal cancer to other serious conditions.
I initially saw my PCP, who prescribed medicine and told me taking Tums was fine, but I wasn’t getting real relief. I had reached my breaking point and decided I needed to see a specialist who truly understood my concerns.
As a Black woman, I wanted a Black doctor who specialized in gastroenterology, knowing that different ethnic groups have unique health factors that need to be considered. That’s when I found Dr. O, and I am beyond grateful.
Why Dr. O & Her Team Are Exceptional:
✅ Same-Week Appointment! – I called over SEVEN gastroenterologists, and the earliest appointment anyone else had was March. Dr. O’s office got me in within two days! That alone was a WOW factor.
✅ Efficient & Caring Staff – The office runs smoothly and professionally. No long waits, no wondering if they forgot about you—just prompt, attentive, and compassionate care.
✅ Reassurance & Expertise – Dr. O immediately put my worries at ease. She explained that heartburn is common but that I needed a stronger medication to manage it properly.
✅ Personalized Treatment Plan – Instead of pushing unnecessary procedures, she listened to my concerns and worked with me to find the best approach for my lifestyle.
The Treatment That Changed Everything 💊
Dr. O prescribed me a stronger medication, and within just three weeks, my symptoms dramatically improved. I now take it every other day (so I don’t become dependent on medication), and I finally feel like myself again.
She also suggested an EGD procedure to assess my condition further, but as a global speaker and event organizer, I couldn’t afford to be down for 14+ days when I had a major speaking engagement coming up. Instead, we agreed to start with medication first, and I’ll follow up in six months.
The best part? I can now eat without fear. Something as simple as a banana no longer triggers painful heartburn.
Final Thoughts: If You Need a Gastroenterologist, See Dr. O!
I am beyond grateful for Dr. O and her team. If you’re looking for a specialist who listens, cares, and actually provides solutions, she is THE doctor to see.
👏 Thank you, Dr. O, for restoring my health and peace of mind. You and your amazing team have a patient for life!

Great staff and professional services
I have been feeing so light/great after this procedure. The doctor and staff were excellent! Thanks and God bless!
Dr. Maryann Osaydne is an excellent doctor. As a new patient, she took the time to answer my questions. She asked questions about my prior Healthcare and the procedures I normally require. She immediately scheduled an appointment for my colonoscopy and my US liver x-ray.
Procedure had been done very well
I had a very good experience with Dr. Maryanne Osayande. She is trustworthy and quite worthy of her profession. I like that she provided me several options on where the procedure would be performed, specifically within the proximity of my home. I had no side effects from the colonoscopy, and she was very proactive with advising me about dietary fiber for my colon. I have referred Dr Osayande to my friends within Sugar Land.
Everyone was considerate and kind. The place was clean. Dr. Osayande was friendly, knowledgeable, and professional. She inspired me to be assured that I was in good hands.
I loved everything about my visit w/ Dr. O. She was kind, attentive, and thorough in explaining things. I really look forward to having her as my long-term GI doctor.
