One Star

I saw Dr. Dengler after I was admitted to Johnson City Medical Center in Johnson City, TN. After many tests it was determined that I had a TIA (mini stroke). I did not see Dr. Dengler until after the test results came back, he visited me in my hospital room and prescribed Crestor and a daily baby aspirin. When I went to his office for a follow up appointment there was no nurse in the room with us, he basically asked how I was feeling, asked me to touch my nose, stand up, sit down and sent me on my way.

Poor office management dishonest dealings.

Poor office staff. Can't be trusted to do what they say they will do. Made arrangements to have botox injections. My insurance was ready to allow me to buy Botox from pharmacy take to Dr. Dr. office agreed to do it that way but insisted they would order it on my Rx plan. I verified they received med. went to appointment Dr. said it was drug they ordered in fact commented, we just replenish our stock with ordered meds. Imagine my surprise when they bill me for drug three months later . Tried to negotiate after all it was their mistake. Office manager sent me a letter saying it was my bill and I had to pay it. I have it in writing they agreed to payments I paid the first one at the front window. Sent in another the first of this month. Now they have returned it. What more can I do.
