Dear Patients,
After many rewarding years of collaboration in the care of patients with sleep-disordered breathing, I am writing to share that I will be retiring from active practice as of October 31, 2025.

It has been both a privilege and a pleasure to work with you and your patients in the field of dental sleep medicine. I am deeply grateful for the trust and professional partnership we have shared over the years.

To ensure the continuity of care for all current patients, I have arranged for Drs Monika Vermani and Gerald L. Cohen of Greenwich Sleep Apnea to assume my dental sleep medicine practice, including all patient records and ongoing oral appliance therapy cases. Drs Vermani and Cohen are accomplished clinicians who share my commitment to evidence-based, compassionate care for patients with obstructive sleep apnea and related disorders.

They will continue to provide oral appliance therapy at:
Greenwich Sleep Apnea
40 West Elm Ave
Greenwich, CT 06830
Phone: (203) 335-0020
Website: www.greenwichsleepapnea.com

I have every confidence that your patients will be in excellent hands under their care. Referrals for dental sleep medicine can now be directed to them and their team at the above address.

It has been a great honor to work together in improving the sleep and health of so many patients. Thank you again for your trust, collegiality, and collaboration throughout my career.

With sincere appreciation and warm regards,

Jeffrey Cahn, D.M.D.
