Dr. Linza is the owner of KnowBull Chiropractic. He has lived in Clarksville for most of his adult life. He served as a Paratrooper in the 82nd Airborne Division and spent over 19 years as a member of the 5th Special Forces Group in Fort Campbell, KY. After retiring from the Army, he attended Texas Chiropractic College in Houston, graduating with a Doctorate of Chiropractic. He then earned his Fellowship in Acupuncture from the International Academy of Medical Acupuncture.

Dr. Linza co-owns KnowBull Beauty with his incredible wife, Carly. He also volunteers as the team chiropractor for Clarksville Elite Gymnastics Center and loves spending time with his family—both human and canine.

Dr. Haston, a Logan University graduate with a Doctorate of Chiropractic, was inspired to pursue chiropractic care after experiencing chronic headaches following an ATV accident. After years of ineffective medication, chiropractic treatment resolved his headaches in just a few visits, inspiring him to help others.

A long-time resident of Clarksville, Dr. Haston graduated from Northwest High School, attended Harris-Stowe State University, and later Logan University. A former collegiate athlete, he remains active and passionate about sports.

Dr. Haston chose to come to KnowBull Chiropractic office for his internship prior to graduation, due to the vibrant and energetic feeling that Dr. Linza and his staff exude. Being the son of a retired Green Beret, Dr. Linza’s attitude, professional approach, and mentorship were exactly what he was looking for in his career.
