December 28, 2019 3:57 PM

Dr. Discher is one of the very first physicians I have had that truly takes the time to listen, looks you in the eyes when talking, truly cares and NEVER types on his laptop when discussing health routines. I am very fortunate to have him as my cardiologist.

November 3, 2019 6:00 PM

Excellent as always. He is always well prepared to discuss my questions and I have his full attention.

November 1, 2019 7:00 PM

Being a caregiver for my parents and having limited time to schedule my own appointments, I really appreciate the promptness of the staff and doctor for my last visit. Even though I had my blood work done weeks prior to my appointment at a facility that my doctor requested, he did not have the results on hand. He explained that it was a computer/network issue and should be cleared up before my next visit in June. However, before my appointment was done, the staff was able to get the results and informed me that everything was good or better from my last appointment. With limited time, I really appreciate the prompt and thorough service I received.

October 27, 2019 7:00 PM

He was wonderful. I was there for a second opinion. I'd like to switch to him. But this practice doesn't take my BCBS Obamacare so I had to pay out of pocket so I'll not be back.

October 27, 2019 7:00 PM

Dr. Discher knows me very well, and some things don't need discussion, so we can cut to the chase. He knows my exercise regimen and in fact my trainer joined me at the recent visit so they could discuss my workouts.

October 27, 2019 7:00 PM


October 24, 2019 7:00 PM

I felt refreshed after speaking with Dr. Discher.

September 15, 2019 7:00 PM

Dr. Discher is always concise but thorough, and is attentive to any changes in my lab results.

September 9, 2019 7:00 PM

Strong encouragement for my diet and exercise program.
