Our Office Staff

Meet our team at CAHC! Please take a few moments to learn about our skilled practitioners and our friendly staff.

At CAHC, we consider it both a great joy and a great responsibility to care for your children. All of our physicians are parents ourselves, so we strive to be understanding and available to the families we are privileged to serve. We are honored that you have chosen us as your child's primary medical doctors and are confident that you will be pleased with the quality of care and service that we can provide you and your family.

A vital part of our service to children begins with our outstanding staff who works hard to manage and maintain a professional, caring and supportive environment for our patients in a timely manner.

Our doctors are lifelong learners. Not only have they received advanced medical training in pediatrics, they continually pursue ongoing education to stay abreast of the latest in child health care.

Your child's health is as important to us as it is to you. We look forward to providing you with excellent pediatric care for your children.

Joe Avni-Singer, MD

Dr. Joe Avni-Singer formed CAHC with Dr. Deborah Ferholt in 1999. He grew up in Albany, NY, received a B.S. from Cornell University and attended New York University School of Medicine. He came to New Haven in 1989 for residency in Pediatrics at Yale, and went on to complete a fellowship in Developmental-Behavioral Pediatrics at Yale as well. After working for several years at the Fair Haven Community Health Center, he joined Dr. Ferholt. He found that she had created a unique practice where doctors take time to get to know each child and family individually and provide care with patience, and respect. Though the practice has grown, Dr. Avni-Singer and his partners strive to maintain these core values and protect the time they spend with patients and families. In addition to addressing preventive care and managing children with illness, he finds great fulfillment in helping parents with the challenges of raising families in our complicated world. Dr. Avni-Singer lives in New Haven with his wife and three children, of whom 2 are now in college.
