About Dr. Razmik Thomassian, MD

I like to think of myself as a clinician and patient advocate, striving for quality patient care in a manner that will maintain the wellbeing of patients in the short as well as long term. In an ever-so-busy and changing medical field, I find the most important part of being a physician is being able to listen to the patient in order to address his/her needs. Whether it is acute or chronic medical concerns, being able to simply listen to the patient will allow for correct diagnosis and medical management. I pride myself in doing just that. Aside from being a physician, I am a family oriented individual and enjoy spending time with my lovely fiancé and big family.
