Our Doctors

Dr. Klemenger and Dr. Marghoob met during orientation at Cornell University College of Veterinary Medicine. They quickly became friends and study partners, and learned that they shared the same philosophy on the importance of the human-animal bond, the role animals play in our lives, and the type of practice they planned to create one day. The dream of Companions Animal Hospital began then. The opening of Companions Animal Hospital was the culmination of years of gaining experience, learning, planning, and dreaming. It has taken a long time, but they are now proud that they have created the hospital where they would want their own beloved pets to be treated. Since the grand opening of Companions Animal Hospital in June 2006, the hospital has been honored to receive commendations and awards from the community. Companions Animal Hospital was recognized by Animal Haven shelter in 2008 with the “Florence Brenner Award for honoring the commitment to helping homeless animals.” Companions Animal Hospital also received the highest community honor of “Merrick Professional of the Year” in 2008.
