About our Providers

Mary Maier, MD, FAAAAI and FACAAI "I believe in empowering patients and their families with knowledge and tools so that they can learn to control their disease, rather than let it control them. We are so fortunate to be able to do this with asthma and allergies. My approach is proactive, with the goal of improving the quality of life for each patient. Today we have the knowledge and ability to control and prevent life threatening and life altering reactions. We employ an integrated team approach partnering with patients and their families, providing education and understanding of their conditions, how their medications work and when, why and how they should be used."

 The Doctors Clinic is a perfect blend of state of the art care and access to a team of excellent providers who can provide continuity of care and integrated care for patients.
