Thank You Dr. Brennan For Your Service!

Dr. Bubak and the entire team at Dakota Allergy thanks Dr. Brian Brennan for his service to our allergy and asthma patients during his time with us.

Dr. Brennan did his allergy and clinical immunology fellowship at Creighton University in Omaha, Nebraska, and he completed his residency in pediatrics at Georgetown University in Washington, D.C. Dr. Brennan saw both children and adults with allergy and asthma problems during his time at Dakota Allergy & Asthma.
