Great doctor and service…read more.. Doctor is great, PA is great, and staff is great. I get prompt service at my appointments and they do thorough testing and following up. Very happy I found this doctor and team in my area.

My husband and I were referred to Dr. Vega for Diabetes treatment by our primary care physician who…read morewas impressed by her phenomenal ability to get patients diabetes under control. I am happy to say that while I still have diabetes I am now undercontrol! My husbands blood sugar level has steadily been coming down. I get the biggest kick out of watching her calculate the dosages of medication and look at the interactions they are having with other drugs. I have never seen a Dr. work that out (maybe they were doing it in their offices) but it gave me a sense that she was really invested in our health and helping us. I am so grateful that I was referred to her. Thank you Dr. Vega ! Adele W

I've been trying to find an Endocrinologist since April and now on the day of my appointment,…read more7/30/25, I discovered that there is inadequate parking for someone who cannot see in the dark. The parking garage is pitch black dark. The staff knew this and did not have the decency or courtesy to tell me this, a new patient. Had I known I could have made other arrangements!!! Never had a chance to see the doctor as I parked on the street, Fannin, and canceled my appointment. So disappointed in the inefficiency and unprofessionalism of the staff.

Dr. Diana Desai is excellent. She is attentive, knowledgeable, and deserves high praise…read more Unfortunately, the office staff is a serious problem. I took time off work specifically for bloodwork, only to later find out the staff never sent the order to the lab. This resulted in wasted PTO, wasted gas, and a completely unnecessary trip. When this issue was brought up, the staff showed no concern or accountability. There was no apology and no sense that my time mattered. It is disappointing that such a great doctor is supported by staff who are careless and indifferent. The lack of follow through and basic respect for patients' time makes this office very frustrating to deal with.

I tried to give this place a chance, and it had failed tremendously twice. October 8, 2024 First time was an in person appointment: one was in training and was the trainer. I wasn't greeted. The trainer treated me as if I was a second class citizen and questioned my insurance as if it weren't good enough. I would have never came here if my insurance did not include this place. Yet, the patiences after me received top tier service. Her entire demeanor was disgusting. My appointment was for Dr. Tang and while she was informative, she gave 0 eye contact. That's extremely rude, especially as a new patient. If someone is talking to you or you're talking back to them, eye contact should be given. Her demeanor is very dry and monotone. She's not very personable. November 21, 2024 I had a televist appointment scheduled originally for 1130 but they moved it to 1115. I waited for over 30 minutes for Dr. Tang to sign in, and she never showed. When I called to see what was going on, they informed me that they would let her know. That time went by and at 1151 I was fed up. I called to get a refund of my money paid and now they're talking about 6-8 weeks. After I receive my money, they will never have to worry about me again. Go somewhere else if you want to be treated properly. All of the staff here need retraining.

This is a review for Dr. Steven M. Petak, Endocrinologist at Houston Methodist Hospital at 6550…read moreFannin Street. I came to Houston from New York with a hyperparathyroid condition and was referred to Dr. Steven Petak at Houston Methodist Hospital. I can't say enough about the wonderful care I received from Dr. Petak. He has always been kind, caring, genuinely concerned about my health. Dr. Petak listens when you speak to him, and he records and addresses all of your concerns with respect. You never real rushed in his presence. Dr. Petak's approach is conservative, which I appreciated, but he will certainly advise surgery if he deems it necessary. Dr. Petak referred me to a wonderful surgeon also at Houston Methodist to correct my condition and now I am well. I must also add that Dr. Petak's assistant, Erica, is excellent! Erica will also take very good care of you. Dr. Petak is truly a 'superdoctor,' a rare gem and a blessing! You'll be in expert hands with him. Highly recommended!

Dr. Qureshi is the BEST! Unfortunately he has left the Endocrine Center at the Methodist and is…read morenow at Kelsey-Seybold Memorial City. If you need a Physician that is attentive, listens to your concerns and has a compassionate bedside manner then he is the Endocrinologist to go see. The Endocrine Center is not bad but I only stayed with them because of Dr. Qureshi. I made an appointment to see him at Kelsey-Seybold and Ms. Alberta was excellent. I do have to wait a month to see because he is very busy but offered to put me on a wait list to get in sooner if someone cancels. I hope this helps anyone with Diabetes or other ailments. He is a wonderful Doctor.

First visit today to see Endocrinologist and what a great experience from making the appointment…read moreover the phone through the actual appointment. The lady at the front desk (I didn't get her name) was great! So professional, personable and very sweet. I didn't have to wait long at all which doesn't seem to be the norm anywhere these days and I already go mentally prepared to sit in hopes to cut down on my annoyance level. Dr. Alexander was great too. He explained exactly what he was going to do and why and listened to me and the questions and concerns I had. Took the time. Probably won't have to go back but would definitely recommend to anyone needing to see an Endocrinologist.
