About DeMera Allergy Asthma & Immunology Center

The DeMera Allergy Asthma & Immunology Center is committed to providing thorough, individualized care to every patient. Unlike other centers, we won’t simply continue prescribing you medications until we find one that works. We’ll take the time to diagnose you correctly, finding the root of your problem and treating it in the most effective way possible.

For allergy problems, you’ll be seen exclusively by Dr. Richard S. DeMera. Board-certified in internal medicine and allergy/immunology, Dr. DeMera is a Valley native who understands the unique problems faced by allergy and asthma sufferers in Central California.

For non-surgical ear, nose and throat, problems, or problems associated with sleep apnea, Dr. Bret E. Sherman, M.D., Ph.D. accepts consultations on a limited basis as an Associate with the DeMera Allergy Asthma & Immunology Center. Board-certified in Otolaryngology and Sleep Medicine, Dr. Sherman is also a Fresno native, and continues to provide high-end, concierge-style medicine to his patients.

The specialists and staff at DeMera Allergy Asthma & Immunology Center pride themselves on providing the best individualized care possible. When you call our offices, we’ll schedule your appointments without delay and answer your questions promptly.

Asthma and allergies affect thousands of people in the Fresno and Visalia areas. If you’re one of them, it’s time to stop suffering and start breathing clearly once again. Contact us today to schedule an appointment.
