About Dr. James Walshe

     Hello my name is Dr. Walshe and I am a New Yorker born and raised in Lynbrook, NY. I am a Chaminade graduate, and an alumnus of Adelphi University where I received a Bachelor of Science in Biology.  I received my DDS degree from New York University College of Dentistry, and I completed my Residency program at Woodhull Hospital in Brooklyn, NY.  

     I love that every day is an opportunity to learn something new as well as to educate others about something I am so passionate about.  I believe that an honorable and ethical patient-doctor relationship is important in order to establish a strong foundation for oral hygiene practices and principles with each one of my patients. The wellbeing and satisfaction of my patients is paramount when it comes to dental care. I feel lucky to be part of a practice that mirrors my ideology, as well as having the opportunity to work along side some of the best Doctors I have encounterd to date at Modern Dentistry.

     I like to spend my free time hanging out with my friends, family, and my dog Ollie. I enjoy going to concerts and listening to live music, as well as traveling around the globe.  Much of my family resides in Ireland, so that is one of my favorite places to travel to!
