Our Veterinarians

Dr. Gwen Sherman

Hospital Owner

Dr. Gwen Sherman has been the proud owner of Mt. Kisco Veterinary Clinic since 2004, and she has developed many long term relationships with her devoted clientele. At a young age, she recognized a passion for working with animals after spending time caring for wildlife, riding horses, and living with many pets. She graduated from Auburn University in 1990 and completed multiple rotating internships. Dr. Sherman’s greatest accomplishment is molding our practice into a modern, cutting-edge clinic while maintaining a warm and compassionate atmosphere for clients and their pets. Dr. Sherman’s special interests include surgery (particularly laser procedures) and oncology. She lives in North Salem with her family and pets including Levi, Cavalier King Charles Spaniel, and cats Willow and Maisy. When she isn’t working, Dr. Sherman enjoys fast cars, travel, spending time at the beach, and horseback riding.

Dr. Jonathan Olsen


Dr. Jon Olsen is a Cornell University graduate who joined our team in 2009 after a year-long medical and surgical internship at Red Bank Veterinary Hospital. His areas of interest include radiology, gastroenterology, dentistry, abdominal ultrasound (he regularly performs ultrasound evaluations at our practice) and nutrition. Dr. Olsen completed special training to become a USDA accredited veterinarian. This means that he is able to prepare and complete international travel certificates for our patients. He enjoys attending regional and national conferences and monthly radiology meetings to keep abreast of developments in his field. Fun fact: He was named one of the 2010 Top Male Executives by the Westchester County Business Journal. Dr. Olsen lives in Thornwood with his wife, Amy, and their pets Slugger, a Miniature Poodle, and cats Sonny and Chandler. He enjoys cooking for his family, sipping single malt Scotch, and creating and solving crossword puzzles in his free time.

Dr. Rachel Albert


Dr. Rachel Albert is a Cornell University graduate who joined the Mt. Kisco Veterinary Clinic team in July 2014. She has special interests in internal medicine and ophthalmology and is planning to become certified in acupuncture. Dr. Albert embarked on her career in veterinary medicine after working in finance on Wall Street. She realized her passion for animals when she volunteered to care for foals at an equine hospital. Dr. Albert loves working with the energetic group at MKVC where, like her, they love what they do and have fun doing it. She takes great pride in being an advocate for animals and values the importance of building long-term relationships with clients. Dr. Albert’s family includes her husband Mark (who is also a veterinarian), her daughter Vivian, and their pets Mimsy (Tibetan Terrier), Chewy (Lab mix), and Griffin (cat). Her special secret talents include beatboxing and break dancing.
