Upon high school graduation, she attended Iowa State University to obtain her Bachelor’s degree before attending chiropractic school at Life University. While at Life University she participated in two mission trips to Haiti and El Salvador where she was able to give chiropractic care to underprivileged villages. She graduated Cum Laude with her Doctorate of Chiropractic in Marietta, Georgia. She is furthering her pediatric and pregnancy education through the International Chiropractic Pediatric Association. Her mission and goal is to educate the community about natural health and healing, while encouraging them to seek an alternative to traditional medicine and supporting them in their journey to optimal wellness. 

    Dr. Winter specializes in pregnancy, pediatrics, and family care. She is certified in the Webster technique, which allows for proper biomechanics of the pelvis and sacrum, creating a birth process that is easier on mom and baby. Chiropractic care throughout pregnancy, birth, and childhood offers choices and benefits for a solid foundation for wellness. She aspires to help families understand that the chiropractic adjustment is a gentle, specific, neurologically based technique that promotes normal development and maintenance of spinal health while expressing whole body wellness.
