Elsinore Pet Clinic Staff

Dr. Costuma

Born and raised in Southern California, I have been in the animal care industry since the age of 16, starting out as a Kennel Attendant. After receiving my Doctorate of Veterinary Medicine in 2002 from University of California, Davis, I have been fortunate to know and help many great pets and their beloved owners. I’ve practiced Veterinary Medicine in Los Angeles County, Orange County and now Riverside County. At the end of 2010 my wife Megan and I (along with our three cats: Miss Meow, Bully and Simon) moved from Orange County to Murrieta where I became the proud owner of Ark Animal Hospital.

Since moving to Murrieta and becoming established in the community, my wife and I have built many relationships with our clients at Ark and have continued to grow in our family. We wanted to continue to extend first-rate and affordable veterinary care to more communities and saw opportunity to do so when Dr. Jerry Ratterree made plans to retire. I took over the reigns at Elsinore Pet Clinic at the end of 2012 and in summer of 2013 welcomed a beautiful, healthy baby boy. 

My associates and I are thrilled to offer Lake Elsinore with the high quality care they expect and appreciate the support that the clients have shown with their loyalty to the Clinic.
