About Us

Fairfield County Allergy,
Asthma & Immunology Associates

In 1971, Dr. Robert Biondi, opened the doors to his private practice in Norwalk and was joined after almost twenty years by Dr. Joseph Sproviero in 1990. The Greenwich office was started by Dr. Redmond (who retired in 2006) during the late sixties and Dr. Mark Litchman came on board in 1989.

Then, in 1998, the Norwalk and Greenwich offices decided to join forces and merged to form Fairfield County Allergy, Asthma & Immunology. The doctors expanded their practice further by adding a third location in Stamford.

The practice continued to grow, as Dr. Mitchell Lester became part of the team in 1999, followed by Dr. Agnes Matczuk in 2003. In addition, Audrey Bregante became our Nurse Practitionier in 2003. Dr. Louit joined FCAAIA in 2009 and speaks fluent English, French, and Spanish.

All of our doctors have hours in each office for your convenience and to better serve the community.
