DRS. MARK LITCHMAN and JOESPH SPROVIERO have practiced together for more than 20 years and each has received “Top Doc” honors numerous times. Dr. Litchman, who received his M.D. from Rush Medical College, and Dr. Sproviero, who received his M.D. and Ph.D. from Columbia University, both completed their allergy/clinical immunology fellowships at Yale and are certified by the American Board of Allergy/Immunology. Dr. Litchman is also board-certified in rheumatology. Their high level of training and vast experience do not limit them to prescribing only the standard protocols of allergy and immunology. They work with other physicians to help patients receive optimal care and get many referrals for complicated and unusual cases. They are honored to practice with Drs. Mitchell Lester, Agnes Matzcuk and Aymeric Louit and Audrey Bregante, A.P.R.N., in offices that are up-to-date with technology and staffed by people who are warm, friendly and professional. All the doctors are attending physicians at Norwalk, Greenwich and Stamford hospitals.
