At Chattanooga Holistic Animal Institute, or CHAI, our holistic philosophy is practiced as integrative veterinary medicine with an emphasis on therapies having a strong tradition of documented effects, careful research, and ongoing study. Integrative medicine encompasses a wide variety of alternative and complementary therapies designed to promote healing and wellness.


Colleen Smith


Dr. Smith is a graduate of Ross University and has been practicing integrative medicine since 2005. She has predominantly worked with small animals, but in 2008 started her own Equine practice that offered primarily acupuncture and chiropractic treatments for local horse owners. She is a certified veterinary acupuncturist through the International Veterinary Acupuncture Society, and has a special interest in dietary therapy using principals of traditional Chinese veterinary food therapy. 

Katie Smithson


Dr. Katie Smithson grew up in Chattanooga, and graduated from the University of Tennessee College of Veterinary Medicine in 2003. She spent the following 11 years working in a holistic small animal veterinary hospital in Charlotte, NC. She and her family moved back to the Chattanooga area in 2014. Dr. Smithson is a certified small animal/equine acupuncturist, and especially loves soft tissue surgery, geriatric medicine, and working with pet owners.
