Dr. Douglas McMahon grew up in St. Paul, MN and currently lives in Woodbury, MN with his wife and three children. As a child, he developed severe food and environmental allergies along with asthma. Based on his own symptoms and experiences, he decided at a young age to pursue a career in medicine to help those that struggle with these same issues. He attended St. Thomas Academy High School. He earned his B.S. degree from Boston College. He then obtained a Master's degree in Physiology and Biophysics. Dr. McMahon obtained his Doctor of Medicine degree from Georgetown University. In addition, he has a pediatric specialty degree from the University of South Florida and a specialty degree in Asthma, Allergy, and Immunology from the University of Wisconsin. He practices as an Allergy and Asthma Specialist in St. Paul, MN.

Dr. McMahon has been named one of the top doctors in Minnesota and in the U.S. for the past 7 years.  

“I became a doctor to help people. Clinically, I am able to help a few people every day.

However, I knew that through medical research I would be able to help hundreds of people every day.

This is why I created AllerMED. I cannot think of a better way to help people than by developing a device

that will not only relieve the anxiety of millions, but also save lives.”
