I love working in ophthalmology because I get to witness the joy in patients when they leave our facility with improved sight. It’s very gratifying to get to be a part of that experience and patient care.” Outside of work Adam enjoys writing and composing music, indulging in his favorite hobby of board games and RPGS, and spending time with his wife and sons.
