Douglas McMahon, MD

Allergy, Asthma


Services Available at OMC:

- Environmental allergy testing and treatments (including allergy shots and drops)

- Food allergy testing

- Lung function testing and treatment for asthma

- Treatment and testing of atopic dermatitis

Length of time at OMC:Before coming to OMC in 2022, I was the director of Outpatient Allergy at the University of MN for 7 years and am also currently the chief medical officer at the Allergy and Asthma Center of Minnesota.

What is your philosophy of care?I grew up with severe asthma, environmental allergies and food allergies, so I know what patients are experiencing. I hope to use that knowledge to help patients in the best possible way.

What do you like to do when you’re not at OMC?As a father of four young children, I enjoy playing with them and attending their sports activities. When I am not with them or working I enjoy playing basketball, softball or golf.
