  • Letter to our patients  - October 20, 2021

    Dear Patient,

    We are sending this letter to inform you of some important changes for our Darien Primary Care practice.

    First, we would like to thank you for your continued support and the feedback you have provided to help us improve on the services we are delivering. We have carefully listened to your feedback regarding the construction at our location. We understand that this makes it difficult for you to park, creates a noisy environment and a less than ideal visit with your primary care provider.

    Unfortunately, we were recently informed that construction would be ongoing for an extended period. Therefore, we have decided to relocate our Darien providers to New Canaan.

    We will start seeing patients at New Canaan Primary Care, located at 38 East Ave, New Canaan, CT 06840 starting on November 1, 2021. This location is just five miles down Rt. 124.

    New Canaan Primary Care is also part of Nuvance Health Medical Practice so your medical records will transfer automatically. You do not need to request your medical records to be transferred to the new office. We want this to be a seamless transition for you.

    At this location, Dr. Michael Schwartz, Dr. Priscilla Agyemang and Kathy Cheslok, LSCW will join Dr. Amy Lohman and Dr. Aesha Patel. The phone number to the New Canaan Primary Care practice is 203-855-3757.

    Dawn Panasy, APRN will see patients in our Norwalk West practice located at 520 West Avenue, Norwalk, CT. The phone number to the Norwalk Primary Care West practice is 203-852-2740.

    We recognize that some of you have future appointments booked in Darien. Please be assured that one of our care team members will be reaching out to reschedule your appointment. You do not need to call us to reschedule.

    Changing locations is sometimes difficult, but we are confident that combining the practices at this location will improve your patient experience. We thank you again for trusting us to be a part of your healthcare journey. Your continued quality medical care is very important to us. We hope that you choose to continue to receive Primary Care services from us.

    If you choose to seek Primary Care services elsewhere, please contact our office for a release of information form, which will allow us to provide your medical records to your selected provider.

    If you have any other questions, please feel free to call our office at 203-662-8900.

    Warmest Regards,


    Cornelius Ferreira, MD FAAFP
