Born and raised in a small town outside of Pittsburgh, Pennsylvania, Dr. Wong was a three-sport athlete and musician in high-school.  He moved to Los Angeles in 2001 to study Computer Science and Biological Sciences at the University of Southern California.  After graduating from the Keck School of Medicine at USC, he completed his Internal Medicine residency at the LAC+USC Medical Center, and he was honored as Senior Resident of the Year during his final year.  After residency, Dr. Wong stayed at LAC+USC for his fellowship training in Allergy and Immunology.

On a personal note, Dr. Wong is married to his high-school sweetheart, Lindsay.  They spend their spare time with their two daughters and miniature dachshund.  When they are not taxiing the kids to soccer and ninja warrior practice, they enjoy hiking, traveling, and exploring new restaurants.

Dr. Wong takes a very personal approach to his patient care, developing a close rapport with all his patients in this small boutique-style practice.  His training at the Los Angeles County Hospital has made him an extremely thorough and experienced physician, providing the highest quality evidence-based treatment.  He is especially adept at the management of difficult-to-treat asthma, allergic rhinitis, eczema, and sinus disease.  He is also well-versed in the most current literature and treatment guidelines for food allergies, drug allergies, immunodeficiencies, urticaria, contact dermatitis, and other skin allergies.
