  • I am so grateful for Dr. Kessel. She is professional without being off-putting, caring, able to listen to concerns, and does the procedure with minimal discomfort. She is supportive of the treatment we are doing in the present and in the future, and does not set up a scenario where surgery is to be expected. Dr. Kessel is always positive about the future of my condition and I thank her for that. Also, the in office and front office staff across the board is caring, pleasant, professional, and comforting. I always feel better after an appointment with Dr. Kessel, even if I am in pain. She and her staff have an exceptional placebo effect on my pain and I love them all for that. (Patient Survey)

  • I have been a patient of ONS for the past two years. I have had two major back surgeries with Dr. Apostolides, several injections from Dr. Kessel, two MRI‘s and multiple x-rays. From the very first day of visiting ONS in Greenwich, I experienced the most respectful and courteous staff of any medical office in my entire life.

    Being greeted at the front desk by well-dressed and helpful security was the first sign that I knew I was going to have the best care. The second floor staff are superior in their handling of patients, not to mention promptly moving patients into the doctor’s exam room. The doctors are top notch and take as much time as needed to answer all questions. Their assistants are well-trained and equally respectful of patients and their families.

    Barbara and Madelyn are exceptional in scheduling necessary procedures and surgeries. Sommre is also easy to work with and very helpful. The desk staff on all three floors are friendly and happy to assist.

    I understand that all staff are interchangeable, which is a unique feature of any medical facility. This most definately adds to their skill level.

    I am writing to express my thanks for a well-organized and smooth operation. My family and I thank you for putting together a wonderful professional group of doctors, nurses, assistants and staff. (DR)
