Dr. Dale Rubenstein

Dr. Rubenstein opened the doors of A Cat Clinic, the first all-feline veterinary practice in Montgomery County, in 1986. A Montgomery County native (and Bethesda-Chevy Chase High School graduate), Dr. Rubenstein earned her BA in Biology from Oberlin College and her DVM from Purdue University. She is one of only 80 board-certified feline specialists in the U.S., and is a member of multiple local and national veterinary and feline organizations.

In addition to participating in Career Days at local schools, A Cat Clinic has been mentoring interns from Northwest and Seneca Valley High Schools since 2009. Dr. Rubenstein and A Cat Clinic also started the Aurora’s Angels Fund to help support cats in the Germantown/Boyds area with needed veterinary care.

Senior cat care is Dr. Rubenstein’s special interest, but she can never resist new kittens! She has two grown children living in Chicago, and she and her husband enjoy hiking and travel.  She currently has one cat at home, Athena.
