Dr Kretzer more attentive than the receptionist and the nursing staff.

09/27/2019

first time meeting with actual Dr...appreciated his detailed explanation.

09/13/2019

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.

*Dr. Kretzer is immediately likeable and showed sensitivity for my concerns. #7-8. Began with referring MD - *S. Patel.

08/29/2019

The staff was very accommodating?

08/29/2019

I mostly interacted with *Dr. Kretzer and *Breanna.

Dr.Kretzer is the best. He fixed my husband 3 years ago

08/24/2019

I felt very comfortable.

08/24/2019

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!

08/24/2019

Dr Kretzer is exceptional. He is the first doctor who actually explained and showed me why I need cervical surgery before I had lumbar surgery! After talking with him my husband and I had the knowledge we needed to make our decisions!

Minimal wait time for such a busy practice. I did not experience any unusual delays.

08/01/2019

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

Appt. @ 10:30 told to arrive 30 min. early, arrived @ 10 a.m. with finished paperwork checked in with ins. & ID by 10:05 called in for vitals @ 10:15 called in to rm. @ 10:25, so basically no wait.

I wrote a follow up letter requesting additional information and had a very quick response by phone from staff & a written response from the doctor.

07/26/2019

I had very little contact with a nurse/assistant. I saw the doctor quickly.

07/26/2019

I did not have contact with staff except check in at desk & weigh in. It was pleasant.

07/08/2019

Dr Kretzer was highly recommended, very happy with entire visit from beginning to end

06/29/2019

04/25/2019

so comforting to experience the competency compassion of the staff and Dr. Kretzer

04/20/2019

The doctor went over everything very quickly, but that was okay with me. I can see how some people might prefer he go more slowly.

04/12/2019

Having a medical background I am very particular about how a physician responds to my questions, Dr. Kretzer was excellent and came highly recommended.

04/09/2019

No delays necessary to be announced; my registration papers were all filled out before arriving for the doctor's appointment

03/23/2019

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.
