Dr. Jacob Duvall
Tulsa Chiropractor
Dr. Jacob Duvall grew up in Tahlequah, Oklahoma, where his entire family is from. At a young age he lost his father to an illness and his desire for the healthcare profession began. He was a very competitive basketball player throughout high school and went on to play basketball at Oklahoma Baptist University, where he won a National Championship as a freshman and met his wife KyLeigh. Due to his mother being in poor health, Dr. Jacob decided to move back home to Tahlequah to be closer to her where he continued his education at Northeastern State University. He graduated from NSU with a degree in Cellular Biology and a minor in Chemistry.
During undergrad, Dr. Jacob’s wife suffered from severe headaches and digestive issues. After getting under principled chiropractic care, her headaches began to go away, as did her digestive issues. Due to Dr. Jacob’s fascination with the human body and the strong desire to help others find true health, he felt like Chiropractic was the perfect fit for him after seeing the results his wife received. He went on to get his Doctorate of Chiropractic from Parker University in Dallas, Texas.
While in Chiropractic school, Dr. Jacob worked to earn extra certifications. He is currently certified in Webster technique through the ICPA, which is a special certification to help treat pregnant women. He has always been passionate about children, so he wanted to make sure he got extra certifications in prenatal and pediatric care.
KyLeigh Duvall
Owner
KyLeigh, Dr. Jacob’s wife, grew up in New Mexico for the first part of her life and then moved to Clinton, Oklahoma, where she was a 3 sport athlete throughout high school. She went on to play varsity volleyball all four years at Oklahoma Baptist University, where she graduated with a degree in Pre-Allied Health. She has always been fascinated by the human body and became even more fascinated after experiencing the relief that principled chiropractic care gave her. She knew that her greatest passion from that point on would be supporting her husband in providing neurologically based chiropractic care to help others find true health.
Outside of the office KyLeigh enjoys being active outdoors, reading, baking, and spending time with Dr. Jacob and their daughter, Brighton.
