Without reservation Dr. Kretzer was exceptional. I have seen other surgeons in the past for this issue. Dr. Kretzer made a very nuanced observation that others have missed, including academics with a background in neuroscience and the spine. I myself have a PhD in Neuroscience, so I'll throw my own credentials behind this endorsement as well. 17/10 amazing

Briana who works with Dr Kretzer is wonderful. She has helped me so many times with either a small issue or a larger issue. She is able to solve problems, be it scheduling, questions that I might have with any of my neurological issues along with Dr Kretzer. She is always a constant there to answer questions that may arise and navagate things for me.

The girl behind the check in desk was swamped with phone calls. She apologized to me, but that was not necessary as she was doing her job efficiently. She had a nice sense of humor!

Dr Kretzer could not be any better
07/31/2019
Excellent; reservations concerning surgery wanted 2nd opinion. Much more comfortable w/*Dr. Kretzer due to attitude re: physical therapy before/after surgery & attempting alternatives prior to surgery.
07/31/2019

Excellent experience. Dr Kretzer is a very knowledgeable, professional and personable physician. He addressed the issue with expertise while taking the time to explain the details using medical imaging to support his diagnosis. He answered questions and addressed my concerns. He is an example of how all physicians should practice medicine and interact with their patients. I highly recommend him.
