Patient Reviews
Feb 07, 2023
I was lucky enough to have Dr. Deassis as my doctor in the ER when he was a resident. He was truly kind, attentive, and thorough. He did extensive imaging and called in an extra specialist to be sure that nothing was amiss. I never felt alone or frightened. He even went so far as to adjust my bed, so that I would be more comfortable and able to sleep. It is rare to find a doctor so considerate of patient needs. Highly recommended!

What’s a board certification and why is it important that my provider has one?

A board certification represents a provider’s dedication to ongoing training in one or more specialties, including the completion of intensive exams.
