Dr. Kellner has been providing urologic care in the Greater New Haven area and the Shoreline since 2005. A graduate of the UConn School of Medicine, he trained at Lenox Hill Hospital in New York City as well as New York Presbyterian Hospital and Memorial-Sloan Kettering Cancer Center. He is board certified by the American Board of Urology.

Dr. Kellner offers his patients laparoscopic, robotic and other minimally invasive techniques for treating urological disease. He has expertise in robotic surgery for prostate cancer and has instructed fellow urologists in learning this technique. A large focus of his practice is men’s health issues, with a strong interest in helping men manage benign prostatic hyperplasia, also known as BPH. Dr. Kellner offers several treatment options for BPH, including office-based procedures such as Urolift, as well as several surgical treatments for BPH including TURP (Transurethral Resection of the Prostate), GreenLight Laser treatment, and HoLEP (Holmium Laser Enucleation of the Prostate). Dr. Kellner is the first urologist in Connecticut to offer HoLEP, and as of June 2022 he has completed more than 500 HoLEP procedures.

Dr. Kellner is a member of the American Urological Association and the Connecticut Urological Society. He is featured regularly on the list of “Top Doctors” by Connecticut Magazine.
