Our Team

Dr. Coleen Dossey has been with Town & Country Veterinary Hospital since April 1995. She earned a B.S in Biochemistry, a M.S. in Animal Physiology, and a Doctorate of Veterinary Medicine (D.V.M.) degree at the University of California at Davis. In addition to practicing traditional veterinary medicine, she has pursued advanced education in integrative medicine and is an I.V.A.S. Certified Veterinary Acupuncturist. Dr. Dossey earned certification by the Chi Institute in Chinese Herbal Medicine in 2014, and is excited to offer both holistic treatment options for your pet, as well as traditional veterinary medicine. When she is not busy tending to the needs of her two dogs and three cats, she enjoys spending quality time with her husband, watching her sons play lacrosse, gardening, quilting, and practising yoga.

Dr. Lisa Mason has been with Town & Country since 2014. Dr. Mason earned her Bachelor of Science degree from the University of Michigan, and graduated with honors from Michigan State University Veterinary School. Before relocating to the Tri-Valley area, Dr. Mason worked at a large multi-doctor veterinary hospital in Southern California for 16 years. Dr. Mason shares her home with Emma, a Thoroughbred, Spike, a Tennessee Walker, and Cassie (a.k.a. Cassidy Buttercup Dandelion), a rescued Golden Retriever mix. In her spare time she enjoys horseback riding, taking her children to and from their various sports and activities, and spending quality time with her husband, family and friends.

Dr. Janelle Castillo has been with Town & Country Veterinary Hospital since 2020. She was born and raised in the Bay Area and has always wanted to work in a profession that would challenge her and keep her thinking. Coupled with her love for animals, the veterinary profession seemed to be the perfect fit. In 2014 she received her Doctorate of Veterinary Medicine from Western University of Health Sciences. She is also a wife, a pet parent to Penny, a Pitbull mix, and Eleven, a Terrier mix, and a mother to three young children. On her days not spent practising veterinary medicine, she enjoys quality time with her family (four-legged and two-legged) and has recently developed a love for indoor plants.

Dr Audra Cook has been with Town & Country since 2021.  She was raised in Kentucky and always dreamed of becoming a veterinarian.  She earned her BS in Animal Sciences at University of Kentucky in Lexington and her Doctorate of Veterinary Medicine at Auburn University in Auburn Alabama (War Eagle!).    She worked in Kentucky for 2 years before moving to California in 2015.    She enjoys bonding with families and their pets and providing an honest, straight-forward approach to their healthcare.    She lives with her husband, 2 young kids, 3 dogs, 4 chickens, a cat, a horse and a pony.   In her free time, she enjoys competitive distance riding on her horse, a mustang.

Diana joined the Town & Country team in 2021.  She came to us after a 32 year career in Veterinary Management. Diana shares her home with her husband and four legged family, Kala, a Dalmatian who thinks she is a lap dog, along with Sequoia, an energetic Patterdale Terrier and Noel, the only cat in the house.  In her spare time, she enjoys gardening, camping, cooking, quality time with family and spending time outdoors, especially in their backyard.

Jessica joined the Town & Country team in 2014. Jessica lives on a ranch so it’s safe to say that she has way too many animals. Jessica shares her life with her cats, Kolby and Ascher, her dogs Ace, Gunner, Tanner, and Molly. If she had spare time she would enjoy riding horses, racing cars, and spending time with her husband and friends. But now life is centered around her new baby daughter, born in August. Congratulations!
