I like that Dr. Weinstock will communicate through email with his patients. He will also help patients obtain financial assistance if prescribed an expensive drug not covered by insurance. I believe that Dr. Weinstock is a good doctor, and very knowledgeable. I do however think he is oblivious to the behavior of his office staff. Latonya is especially rude. She really needs to be in a position with no contact with the public. Trish is also not very compassionate or caring.

Dr. Weinstock shows no real interest in his patients. I question his medical ethics. His staff is rude and has no business working in a medical office.

I had two encounters with Dr.Weinstock both of which I felt relieved that I had chosen the right physician. The first was a colonoscopy that found a cancerous tumor that was removed before it spread. A follow-up procedure a year later found nothing. The second encounter was a partially blocked lower bowel which is treated with three options. The first and easiest option was an antibiotic which happily worked for me.

I only saw Dr. Weinstock once as he had my records from my prior GI specialist who left his practice for Dallas, TX. I visited Dr. Weinstock as he is well known in the St. Louis medical field given his focus also on SIBO and rosacea. SIBO negative but they never told me the results. Rosacea...see a dermatologist. He offered me no real solutions. I was generally not satisfied with the staff being unfriendly, or on the phone with outright rudeness. I found a new GI instead as did my mother.
