My poor daughter is a patient of Dr. Bhatka. This woman is MIA. She missed a scheduled virtual visit and cannot be reached AT ALL. This behavior is not indicative of quality specialty care. My daughter cannot get a simple prescription refill even though she has set up a virtual appointment that Bhatka didnt show up for.

Experience here has been great over the last year. Anytime I have needed something within business hours they have it turned around in no time. The two Drs Ive been talking with have been very supportive and listened to my concerns and problems. Compared to many other places Ive been through in Houston, this is the best treatment Ive received

So i was seeing a psych here for about 2 years, and was dropped by that psych with no referral to another one.. i also wasted money doing TMS which they claimed would help me, but actually made things worse. does good mental health care exist anywhere?

I have never suffered such aggravation from a healthcare office. Like other reviewers have mentioned, reaching the office via phone is hit-or-miss at best. It takes about five attempts reach someone to schedule an appointment. Phone sessions are 15 minutes after the initial consultation but still billed as a full hour. Emails are often missed or ignored; I've never had to send so many follow-ups just to receive a response. They charged $35 for a single sheet of faxed papera sheet of paper that I had to route through two secretaries and two (answered) phone calls over the course of several weeks

The office at Greater Houston Psychiatric Associates is very difficult to deal with. It is almost impossible to make an appointment. The web says the office is open from 8:30am to 5:00pm. I call at 8:35 am and the recording says they are open at 9:00am. I call at 9:05am and the answering service answers and says no one can come to the phone so leave a message. I left a message and we will see how long it takes to get a call back.The recording at the office also states that they are closed for lunch from 11:00-1:00. I called at 1:05pm and the answering service says they are closed from 11:30-1:30pm

I've been a patient of Dr. Giray for a little over a year now. I absolutely love her and the staff at the front desk. Everyone is super nice!

I have been getting psychiatric care here for more than 6 years, I have had 2 different insurance plans, and periods of time with No insurance at all, financial hardships, unemployment, and they have Always been accommodating no matter what my situation may be. People who are leaving negative comments should probably be ignored - i have seen a lot of people throw drug-seeking tantrums - and so they don't come back because they quickly realize that doesn't fly here. This place and the doctors and staff here are not naive in the least - they are professional and take psychiatric care seriously.
