Dr. Lori Hageman

Veterinarian at Ark Pet hospital CA

Dr. Lori Hageman

Just six years after receiving her education from the University of California School of Veterinary Medicine - DVM and gaining some valuable veterinarian experience, Dr. Hageman decided to pursue her dream of opening up her own veterinary hospital. It was in 1999 that she opened up the doors of The Ark Pet Hospital, Inc. This year marks her 15th year practicing veterinary medicine in East Contra Costa County.

An active member of the American Veterinary Medical Association (AVMA), California Veterinary Medical Association (CVMA) and the Association of Reptile and Amphibian Veterinarians (ARAV), Dr. Hageman likes to keep herself busy in and out of the animal hospital. She's also the past President of the Contra Costa Veterinary Medical Association (CCVMA). One of her many passions is teaching and giving back to her community, so she has served on the Small Animal Advisory Board for the Teaching Hospital at the UCD Veterinary School and is on the Board of Trustees for the Oakland Zoo.

Dr. Hageman has a special interest in surgical cases and has taught at the UC Davis School of Veterinary Medicine in the Student Surgery department. Dr. Hageman, her husband John, and their children Mallory and Lucas live locally and share their home with 1 dog, 2 cats and 3 tortoises. When she's not at the hospital, Dr. Hageman is at the racetrack or in her craft shop. She's been driving cars on the big tracks for 12 years and has raced at Laguna Seca, Infineon Raceway, Sebring International Raceway and other nationally recognized tracks. Dr. Hageman welcomes you to The Ark Pet Hospital and looks forward to helping care for your family.

Dr. Don Schlange Dr. Don Schlange

I graduated from U.C. Davis in 1993 and immediately started working in Antioch. After 21 years I still can not imagine doing anything else. My passion has always been in general medicine but I have special interests in Diagnostic Ultrasonography, Dentistry, and surgery.

I live with my beautiful wife and two step daughters. Currently we have 5 cats (Oscar, Gary, Soot, Lex, and Lou), and 12 Geckos. Anybody interested in a baby crested gecko? ;) My favorite hobbies are spending time with my family, mountain biking, camping, tennis, and taking care of all the geckos.

Dr. Ilana Halperin Dr. Ilana Halperin

Dr. Ilana Halperin grew up in the East Bay Area. Since childhood, she has had a passion for animals and science, and found veterinary medicine to be the perfect blending of these interests. After graduation from veterinary school, she completed a rotating internship in veterinary internal medicine and surgery in Albuquerque, New Mexico. She returned to California in 2004.

Dr Halperin lives in the East Bay with her 3 brilliant cats and her Australian Shepherd dog. In her spare time she likes to garden, do yoga, SCUBA dive, draw, and make jewelry.

Dr. Halperin's interest in acupuncture grew after she received acupuncture for a knee injury and was impressed with the results. Realizing that this could be a wonderful addition to her practice of veterinary medicine, she pursued training through IVAS. Since that time she has been happy to see positive results in her patients using acupuncture to treat such conditions as arthritis, back pain, allergies, and inflammatory bowel disease.
