  • Jory W. Olsen, D.V.M., Dip A.C.V.I.M.

    Jory grew up in southern California and enjoyed the sunshine, weather, and beaches there. After completing an undergraduate education at San Diego State University, a PhD program at UCLA in biological chemistry was chosen to research basic cancer development and behavior. Deciding to move into a more clinical medicine and taking advantage of his love for pets, Jory left UCLA with his masters degree and went to veterinary school.

    Jory graduated from veterinary school at the University of California at Davis in 1988. He completed an internship at Texas A&M University before returning to UC Davis for a residency. His primary interests during the residency were intestinal disease and food allergies, kidney disease and progression of degenerative disease, cancer therapy, and novel therapy for fungal disease.

    Jory moved to Atlanta in 1992 and joined the Veterinary Internal Medicine Specialty Practice staff. In 1994 Jory took ownership of the practice and moved to the present location in 1997. The practice is based on the ultrasound skills established by over 20,000 ultrasound examinations, chemotherapy treatments for a variety of cancers but focusing on lymphoma, endoscopic evaluation of the intestinal tract, respiratory tract, and general endocrine and hematologic internal medicine experience. Jory is boarded in small animal internal medicine with the American College of Veterinary Internal Medicine (ACVIM). The majority of cases seen are challenging referral medical patients that have failed to respond to primary care and other referral center care.

    Jory has given multiple presentations to the A.C.V.I.M. national meeting, regional veterinary meetings, local veterinary associations, and dog and cat breed clubs.

    Jory enjoys the job of helping pets resume a better quality life and trying to restore pets to their place in our families. Outside of the business, Jory enjoys his family of wife, Diana, and two girls, Kayla and Jacqueline. Traveling is a favorite pasttime. Jory also enjoys activities like tennis and bicycling. At this time, Jory has four cats and two dogs but the numbers have varied over the years.

  • Diana L. Olsen, B.S., D.V.M.

    Diana grew up in Pittsburgh, Pennsylvania and enjoyed the snow and changing seasons. She enjoyed the hustle and bustle associated with being one of six kids in the family.

    Diana went to veterinary school at the University of Georgia and graduated in 1991. She practiced for six years in the Atlanta area before traveling and teaching ultrasound to veterinarians and clinics around the country for 2 years.

    Diana started her practice in 1999. She has performed laser surgery for tumor removals, declaws and soft palate resections and other oral surgery since 1999. She has performed many challenging surgical procedures because of her skills and association with the internal medicine practice. Among those surgeries are: patent ductus arteriosis closure, adrenal tumor removal (including removal of invasion into major vessels), liver lobe removal, lung lobe removal, bile duct rerouting (cholecystoduodenostomy), intestinal rerouting (bilroth), pericardectomy, thoracic duct ligation, laryngeal tie back, rectal tumor removal by eversion and prolapse.

    Following completion of her five course orthopedic surgery training at the University of Tennessee, she has performed many cruciate ligament repairs, patellar luxation stabilization, fracture platings and external fixators, and hip luxation repairs.

    She enjoys surgery and the opportunity to make an immediate impact on her patient's quality of life.
