Dr. Nicholas Tomasiak

Education: Logan College of Chiropractic

Hometown: O'Fallon, MO

Dr. Nicholas Tomasiak grew up in a uniquely chiropractic family—24 members strong—where caring for others was more a way of life than a chosen career path. Surrounded by the benefits of chiropractic care from an early age, he was inspired to continue this legacy of healing and service. Instead of a singular “aha” moment, Dr. Tomasiak’s desire to help people developed naturally over many years of witnessing firsthand how transformative chiropractic care could be.
Patients appreciate Dr. Tomasiak’s easygoing yet humorous personality and his genuine ability to connect. He takes time to listen intently, tailoring each session to address immediate concerns while also guiding patients toward long-term wellness. For Dr. Tomasiak, “wellness” isn’t a buzzword—it’s a holistic integration of physical, mental, and spiritual well-being, fueled by mindful self-care and a sense of purpose.
In his personal life, Dr. Tomasiak maintains this balance through reading and spending quality time with his wife and children. An avid outdoorsman, he often recharges by camping, fishing, hunting, and gardening—activities that ground him in nature’s rhythm and remind him of the importance of holistic living. Through this lifestyle and philosophy, Dr. Tomasiak strives to inspire his patients, helping them discover their own path to vibrant, lasting health.
