I feel that the care I received from Gretchen and Dr Parker was excellent. It has helped me relax about the laboratory abnormality and, also, motivate me to take even better care of my health.

The doctor ordered a few more blood tests and a urine test. The doctor said his services were no longer needed when they came back normal.

Communicated well w/ PA and junior (?) Dr. Seemed as though Dr Parker was annoyed by my visit. Had his hand on the doorknob the entire time. I'll be very happy to see his colleague, Dr Kelsey Bonar (?) , again anytime.

I thought I he PA Kara was awesome! Super friendly and personable. Dr. Parker was very kind as well. Very quiet. I trust his knowledge. I would have e felt more comfortable had he sat down. I felt awkward looking up at him. Otherwise, my visit was quick and he was very nice.

As mine is an on-going condition, we simply monitored my current status - noting little change or reason for alarm. All my questions were addressed to my complete satisfaction.

Dr Parker's NP/PA was very kind and explained a lot to me about what was going on. However, when Dr Parker himself came in, he was barely in there for even 2 minutes and didn't explain anything to me! Just said that the blood work I came in for wasn't concerning, it may just be "my normal." Then he ordered extra blood tests, but he didn't give any other explanation as to why or the risks of my levels being abnormal. He just said that they would contact me the next day, which didn't happen. Anyway, thank you to Dr Parker's NP/PA for helping me out and for being so kind!

My care providers did their best to allay any concerns, I may have. The unanswered segments do not apply at this time. I feel assured they will be diligent in trying to obtain a diagnoses.
