Brentwood Animal Clinic has been owned and operated by Dr. Philip C. Hightman since 1987. Dr. Hightman is a graduate of the University of Illinois. A few years after graduation, Dr. Hightman relocated to Jacksonville to be close to his family.

Although Dr. Hightman is primarily a small animal practitioner, he has a strong love and respect for all of the animal kingdom. He has also been an equine veterinarian for over 20 years and is the veterinarian for many of the working canine dogs for the Jacksonville Sheriff's Department, FHP, Federal Reserve, and the JIA Airport police. He also assists the JSO with animal cruelty cases.

In 1990, Dr. Hightman was drawn towards holistic medicine so that he could offer both traditional and alternative medicine to his patients. He is a licensed veterinary acupuncturist as well as a certified Chinese herbalist. He continues to study the many alternative healing modalities, which include chiropractic adjustments, homeopathic remedies, NAET-allergy elimination treatment, and Tui-Na, a Chinese medical manipulation that is used for preventing and treating diseases. Dr. Hightman's knowledge and enjoyment in practicing veterinary acupuncture evolved from the fact that he is also a board-certified Doctor of Oriental Medicine and Acupuncture Physician for people.

Dr. Lynn Sattesahn has been a veterinarian for over 17 years and enjoys internal medicine and diagnostics.
