Long before Olympia Allergy and Immunology was established, Dr. Welch grew up with humble beginnings. He valued education more than anything and strived hard to finish college and grad school.
Taking up a biology course in a community college, Dr. Welch’s life perspective turned upside down when one of his teachers asked him about what he really wants to do with his life. Apparently, being an oceanographer or a traveler was out of the question.
Dr. Welch went to a private school to do his formal science training and ended up going to Louisiana for grad school. He felt a pull towards practicing the science of allergy and immunology after seeing a nurse doing a skin test procedure.
Hard work and twenty years later, Olympia Allergy and Immunology was born, named by his daughter, signifying how they had to climb a mountain to reach the skies. And now we’re here.
