Mark Eisner, MD's Performance

Testimonials

"I felt at ease with his tone, demeanor & willingness to listen"

I contacted Dr. Eisner for a second opinion before making a decision on colon surgery. Immediately, I felt at ease with his tone, demeanor and willingness to listen and put me at ease. Keep in mind that this was a first appointment and it was a tele-med appointment. Looking forward to my in-person appointment next month.
