Awesome

The patient should be allowed to have the choice of seeing a physician or a PA. The next years appointment card given to me was for the PA. I only noticed it once I returned home. This practice has traditionally been excellent from my past experiences with the physician and staff,, however in this instance everything seemed to be hurriedly done. I sincerely hope that physicians can take charge of the patient’s ultimate health and wellbeing.

No significant complaint but things were rushed a bit causing me to forget to ask a few minor questions. Not a big deal. Dr. needed to move on to deal with others so it is up to me to be quicker to ask those few things I forgot.

Dr. brenner is incredible. Not only he taken great care of my health, but also he great to speak with at every appointment. It’s rare to find a doctor that combines such personal touches and care for a patient as a person with outstanding quality of medical care. He takes time to go over the diagnosis clearly and treatment options
From his excellent treatment, curiosity, investigative mind and ability to connect, you know where you stand immediately and what next steps look like.
