Our philosophy
Allergies and asthma shouldn’t decide where you go, what you eat, or how well you sleep. We find out what’s behind your symptoms, treat it, and keep checking in until you feel better.
Pick the symptom that bothers you most. We’ll figure out what’s causing it and what to do about it. Every plan starts with a clear diagnosis. After that, we follow up and adjust it if something isn’t working.

Three decades. One dedicated specialist.

Dr. Scott I. Song is a board-certified allergist-immunologist with more than 30 years of experience. He is also board certified in internal medicine, which gives him a broad view of your overall health.
As a U.S. Army Major, he served as an allergist and cared for more than 200,000 soldiers and their families throughout Europe. That experience still shapes how he practices.
Your plan is based on your history and your triggers. Then we follow up and change it if something isn’t working.
“I really enjoy putting together a plan that makes a lasting difference for someone. My goal is to help you live without allergies and asthma holding you back.”
