I don't usually take the time to write reviews, but I thought that I should pass on my concerns about this doctor. While I understood that he did not want to schedule two procedures on the same date (for billing purposes) I politely told his office staff that I was going to another facility where it is standard practice to perform both at the same time. Dr. Gretsinger felt it necessary to send a letter to me that states that I will not be able to receive services from their office in the future. I will let you draw your own conclusions.

Seems very pompous and made me feel as if I was defending myself. Did not enjoy the experience at all. Would not recommend him at all. No bedside manner and never follows up or communicates test results.

If you are referred to this Dr., reconsider. Poor communicator, pompous and generally not interested in your condition. Communicated symptoms to the nurse during the previsit and it was clear he did not read any of the notes. Couldnt get a word in edgewise.
