Dr. Steve Hong
Quotation: "Participating with Horizon fits with my practice’s mission and vision because I can serve patients who may not have access to care otherwise. I have been treating all my patients as if I’m taking care of my own family and friends. I am also thankful that I can provide the best service to my community and surrounding areas. Dentistry is challenging, but one of the main reasons I can do it every day is because of all my supporting team — front desk, assistants, administration and clinical staff. Having practiced for 24 years, I know there is still so much to learn and room to grow, but at the same time, I am confident that all my patients are in very good hands because of our genuinely caring team."
Bio: Dr. Steve Hong graduated from Cornell University obtaining a B.A. in Biochemistry. He attended Tufts University School of Dental Medicine, earning his DMD in 2001. While attending dental school, Dr. Hong received the Navy Health Service Collegiate Program Scholarship, the catalyst to his enlisting in the United States Navy Dental Corp from 2001-2004 and ultimately earning the rank of Navy Lieutenant dental officer in Camp Lejeune, N.C. During his service, he was deployed to Kuwait for five months and given the unique opportunity to serve as a lead dental officer in the Alpha Surgical Company in Operation Iraqi Freedom.
Since his honorable discharge from the Navy, Dr. Hong has been dedicated to delivering excellence in dentistry in a private practice setting, serving patients in South Jersey and Philadelphia. With a gentle hand and an eye for perfection, Dr. Hong’s expertise spans all aspects of Comprehensive Dentistry, from routine fillings to cosmetic dentistry, crown and bridge, root canal therapies, oral surgery and implant dentistry. He is committed to listening with compassion and providing the highest quality dental care to everyone who walks through the door.
Dr. Hong and his wife live in N.J. with their two children. Through his church, he has volunteered in dental mission trips to the Dominican Republic and Haiti. In his spare time, he enjoys hiking, biking, spending time with his family, and is an avid pickleball player.
