Ashley Weinberg, DVM – Practice Owner

Dr. Ashley Weinberg grew up in the Northeast and has known she wanted to be a veterinarian since she was 5 years old. Her veterinary career started in 1994 when she began working as a receptionist and assistant in a veterinary hospital in New York. She attended Michigan State University’s College of Veterinary Medicine and graduated in 2001. After graduation, she practiced in North Carolina for two years before moving to North County in 2003. She then worked as an associate veterinarian at other local animal hospitals before deciding to open her own practice in August 2013. She has a special interest in pain management and dental care. She regularly attends continuing education seminars to help provide the best care for her patients. Dr. Weinberg lives in San Marcos with her husband, two children, and Golden Retriever named Avery.

Tanya Adams, DVM – Associate Veterinarian

Dr. Adams is thrilled to be part of the team and practicing at Twin Oaks Animal Hospital. Her true professional interest is akin to that of a family practitioner where she strives to develop and maintain a long-term relationship with her patients and their owners.

Her professional interests focus on the medical, surgical, and dental care of dogs and cats. She has a special interest in endocrinopathies (hormone-related diseases such as diabetes, Cushing’s, and thyroid illnesses), dermatology, and treating cats as well as their unique medical conditions. Dr. Adams enjoys preventive medicine as well as the challenge of managing the medical concerns of her patients as they journey through the various stages of life. She strives to always provide friendly, personalized, compassionate care.

The family cats, Jack and Crookshanks, allow their home to be shared with Dr. Adams, her husband, and two daughters. In her free time, Dr. Adams enjoys running and camping with her family.
