About Us

North Bay Allergy and Asthma was founded in March of 1989 by Dr. Larry Posner. Offices were established in the cities of Napa and Sonoma. Since then, the practice has grown and now we have 3 physicians and a physician assistant working to care for your allergy and asthma needs.

Our Mission

We provide the most cutting edge of allergy technology, ranging from skin testing to desensitization programs. Working and living in Napa has been tremendous over the years, and our staff is delighted to be able to serve the Napa and surrounding communities. We have patients from as far as Davis and San Francisco, and from the far corners of Napa and Sonoma Counties. We treat all types of allergic and immunological diseases, and collaborate with local, regional and national thought leaders to provide you with the best possible care to achieve the best possible outcomes.
