Dr. Windt has treated asthma, allergy, and respiratory disease across the seacoast region for over thirty years.
Every patient receives a plan built around their diagnosis, history, and daily life — not a one-size-fits-all protocol.
We give patients the information and resources to understand their condition and manage symptoms with confidence.
"The Pulmonary Rehabilitation Program gave me the tools to improve my body's function. You don't just exercise — you learn the many facets of the disease and how to get stronger and healthier."
"Great staff. My allergies, asthma, and upper respiratory illness have significantly improved over the past 13 years."
"A life-long asthmatic prone to serious infections — Dr. Windt got my health under control and prescribed pulmonary rehab. At 81, I'm in the best shape of my life."
"With severe allergies and asthma I was constantly tired. After treatment and pulmonary rehab, I can hike with friends and keep up with my kids. At 43, it's a whole new life."
