Dr. Randi Cohen
This physician is not currently rated. Why?

Why is this doctor not rated?


To ensure the accuracy of our patient satisfaction scores, we require that providers who see patients receive a minimum number of completed patient-submitted surveys before their reviews are listed on their profiles. Star ratings on this site are collected on a rolling basis from the previous 12 months.
Additionally, some of the physicians listed on our site do not see patients directly, and therefore, do not receive evaluation and ratings from patients.

When COVID-19 hit, I decided it was time to retire from a lifetime of teaching art and do more traveling with my partner Joe. We purchased a tiny trailer and spent a year and a half visiting family and scenic vistas. Our travels were put on hold, however, when I was diagnosed with not one but two cancers.
