Dr. Samantha Abair

Owner and Veterinarian

Dr. Samantha Abair was born in Upper Heyford, England on a military base where her father was a US Air Force pilot.  Her love of horses started at age three when she began riding at her grandmother’s farm. From that point on, when asked what she wanted to be when she grew up, her response was always “a horse veterinarian!”

As she grew up, Dr. Abair never wavered from her lifelong career goal. She took summer jobs at local veterinary clinics so she could learn the industry. She continued to ride, competing in various equine disciplines throughout high school and college. Samantha obtained her bachelor’s degree in Animal Science from California Polytechnic State University, San Luis Obispo. She then went on to earn her Doctor of Veterinary Medicine (DVM) from Western University of Health Sciences in Pomona, CA. After her formal education, Dr. Abair elected for an intensive year-long internship in surgery and internal medicine at West Coast Equine in Somis, CA.  

Over the past decade Dr. Abair has worked in the greater Los Angeles area, establishing herself as a premier provider of equine medical care. Her conscientious approach to medicine, commitment to patients, friendly nature, and integrity have made her a favorite among many in the area.

Dr. Abair created Topline Equine Veterinary Inc. to further her capacity to provide excellent veterinary care. This independent practice serves the regions of the San Gabriel Valley, Pomona Valley, and northwest Riverside County.

Dr. Brenda Stadelmann


Dr. Brenda Stadelmann moved to the San Fernando Valley as a young girl. At the age of 8, her mother signed her up to join the Blue Shadows Mounted Drill Team in Lake View Terrace to try “something new”. This new sport laid the foundation to decades of riding and owning horses, which eventually led to discovering her passion in veterinary medicine.


After years of rigorous instruction, clinical experience, and volunteering, she earned an associate’s degree in Pre-Veterinary Medicine from Los Angeles Pierce College. She then achieved a Bachelor of Science with a minor in Equine Medicine at California Polytechnic State University, San Luis Obispo. Through her educational experiences, as well as veterinary ride-a-longs at Santa Anita racetrack, Dr. Stadelmann developed an interest in equine reproduction and sports medicine. She earned a Doctor of Veterinary Medicine (DVM) from Atlantic Veterinary College on Prince Edward Island, Canada. Although she enjoyed her adventures up north, including learning how to drive through blizzards, Dr. Stadelmann returned to Southern California to complete a year-long, surgery and internal medicine internship at West Coast Equine. Now an associate at Topline Equine Veterinary, she looks forward to continuing her veterinary career.


During her spare time you might find Dr. Stadelmann riding her horse Sancho along the mountain trails, training her deaf cattle dog Zoey or enjoying all the little restaurants in her community. 

Alex Russell

Veterinary Technician

Alex was born and raised in Southern California.  Her deep love of animals started at an early age and eventually developed into the ultimate goal of becoming a registered veterinary technician (RVT). She started her career volunteering at animal shelters, cleaning stalls and working for local barns guiding trail rides. She continued this passion while in high school and after graduation attended a community college to temporarily follow her love of photography.  After living in Florida for a year she returned to California and enrolled at Penn Foster College to become an RVT.  Alex has worked with Dr. Abair since 2016, developing a strong partnership that has contributed to her professional growth.  She currently lives with her 2 dogs Brigit and Yufi along with a menagerie of other pets.

When she isn't working, you might find Alex at Disneyland, in a barn grooming horses, photographing wildlife and animals, playing with/training her dogs or at a hockey game.
