The worse experience of any medical professional I have ever experienced. Staff rude. Waited over an hour in a closet type room to be seen. Could not understand what he was saying. Did not explain well. Wants me to have surgery without looking into other things first. Wanted to take me off medication from my cardiologist and internal medicine doctors. Would never recommend nor never going back. Don’t trust him!

I appreciate him answering all my questions and adding good advice. He is a kind and caring doctor. I've been with him for many years and not had one issue. Never a long wait time.

Dr. D is treating my Dad for the last 3 years ; exactly at the time when covid hits. The way he handled my Dad's diabetic needs and follow ups, I highly highly recommend him as I found him to be very through, knowledgeable and with immense patience.

Dr. D is fine---thorough & competent. Staff are HORRIBLE. Phones don't get answered. Voicemail messages don't get returned. And forget getting a refill.

I have been waiting 10 days for the office to get their act together and call my insurance co for a prior authorization. 4 times the office told me they submitted the prior authorization and 4 times my insurance company has told me they have not received anything from doctor. it appears the staff has no clue how to submit a prior authorization for medicine. No confidence in the office. will have to go to another doctor.

I am very happy with the services that I have received from his office and by the Doctor himself. A very friendly staff and happy atmosphere.

I feel only the people that don't like him have judged him here. He is a get to the point...very knoledgeble doctor. That is why we like him...and other's might not.

Just awful regarding treatment of thyroid/hormone issues. I have pre-diabetes and keep gaining weight and he keeps me undertreated all the time and expects me to wait months before seeing me and testing me again. I have moved on to someone who can actually treat.

Did not diagnose me but gave me tests to do and I return in 2 months, so we will see.
