Jessica Castaneda, DVM

Jessica Castaneda, DVM (formerly Dr. Sovereign) joined the team at Westridge in August 2015. She fulfilled her life-long dream of becoming a veterinarian after completing her Bachelor of Animal Science and Doctor of Veterinary Medicine degrees at Oklahoma State University in Stillwater, Oklahoma.

Originally from Ada, Oklahoma, Dr. Castaneda moved to the San Antonio area in 2013 and has been working as a general practitioner since that time. Her interests include preventive care, dentistry, Traditional Chinese Medicine and allergy management.

As a strong believer in life-long learning, she continues to further her knowledge of preventative medicine and general practice. She strives to create comprehensive, holistic management plans for her patients with the life qualities and preferences of the individual pets and their people in mind. In addition to the incorporation of conventional methods, she is currently pursuing certification in Traditional Chinese herbal medicine and later in acupuncture in order to offer more modalities to her patients. With her professional attitude, dedication, positive presence, compassion, and excellent communication skills, she works hand-in-hand with the entire Westridge team in the pursuit of providing those in her care with overall health and well-being.

Dr. Castaneda and her husband Tim have a son, Mitchell, as well as two dogs, a Lab mix named Mox and a terrier mix named Bindi and two cats, Yoko and A Boy Named Sue. The Castanedas love to spoil their baby and pets as much as possible. Dr. Castaneda enjoys spending time with friends and family, camping, hiking, and horseback riding and toys with the idea of becoming a Master Naturalist one day.

Teresa Fransik, DVM

Teresa Fransik, DVM is a passionate believer in the health and wellness of people and their pets. She was trained as a traditional veterinarian and graduated from Texas A & M College of Veterinary Medicine. After an incident in 1998 with her beloved dachshund, Becky, she quickly discovered the value of chiropractic medicine when her own personal Chiropractor eliminated Becky’s severe neck pain. At the time, the laws of Texas would not allow for chiropractic adjustments of pets by veterinarians; however, years later when Dr Michelle Bammel suggested that she go back to school to get certified in Animal Chiropractic by AVCA, Dr Fransik was all in.

Dr Fransik loves helping her patients by providing gentle and accurate manipulation therapies of chiropractic adjustments and myofascial release to provide immediate and long-term release of muscle tension and pain. Her patients love to come in for their regular adjustments. She is also currently working on her certification as a Veterinary Food therapist through the Chi Institute, focusing on weight loss in overweight and obese pets.

Dr Fransik loves to hike with her husband, David. Since Texas does not have large elevation changes, they spend most of their time training for their next big hike in a new and beautiful location. She is also currently training to become a Certified Life and Weight Loss Coach.

Karly Brightwell Jimerson, DVM

Karly Brightwell Jimerson, DVM is joining the team after completing her Doctorate of Veterinary Medicine at Texas A&M College of Veterinary Medicine.
She is originally from the Houston area. She completed a Bachelor’s of Science in Biology and a Bachelor’s of Art in Spanish while playing Division I soccer at the University of the Incarnate Word, in San Antonio.

Ever since she was little, she always wanted to become a veterinarian. Although her friends and family expected this answer to evolve into an astronaut, then a ballerina, and then into a more attainable goal. It never did. The veterinary medicine field is full of compassionate, intelligent, and inspiring people, that she admires with all her heart. She hoped to one day join this amazing field. Her dreams came true.

With this passion, she hopes to provide all of her patients and clients with an incomparable experience focused on building strong, lasting relationships coupled with excellent quality of medicine. She believes in honesty, in faith and family, and in service to others. She believes in hard work, dedication, and kindness towards others and towards oneself. She will embody all her core values to better serve this community as one of its veterinarians.

When Dr. Jimerson is not working, she enjoys spending time with her family and friends. Dr. Jimerson and her husband, Wade, enjoy spending time at the lake and the river, as well as, fishing and hunting. Their dog, Henry, enjoys running around outside but is still learning how to swim. Their rabbit, Arthur, lives for treats and snacks. I don’t blame him! Most importantly she cherishes their time together as a family and looks forward to their future together.
