Our Chiropractors are here to serve you

Dr. Lacie Drennan

Dr. Lacie Drennan

St. Charles

Education: Northwestern Health Sciences

Hometown: Larrabee, Iowa

Dr. Drennan's patients leave her clinic determined to live their best lives. "We only get one life to live," she reminds them, and overflows with joy when they tell her how chiropractic changed theirs.

Growing ...up in Larrabee, Iowa allowed Dr. Drennan to develop a relationship with chiropractic early in life. After a severe car accident left her with chronic, debilitating migraines, the 15-year-old found herself plagued by constant nausea and pain, which forced her to miss classes and sporting events. Multiple medications failed her. After an MD even told her that if she avoided dairy, chocolate and gluten her migraines "might go away" in a few years, she went to a chiropractor who relieved her pressure and resolved her pain. "Chiropractic gave me my life back," she tells hopeful patients. After that first adjustment she knew she wanted to become a chiropractor to help others avoid the suffering she went through.

Wellness for Dr. Drennan means benefiting from lifelong chiropractic care — both therapeutically and preventively — without relying on drugs and surgery. She maintains her wellness by playing volleyball — on the court in the winter in the sand during summer, and at tournaments all year long.

After completing her BS at Buena Vista University, Dr. Brennan was a Dean's List graduate of Northwestern Health Sciences University, where she earned her Doctorate of Chiropractic as an active member of the Health and Wellness Fitness Club and the Student American Chiropractic Association Sports Council.

An active member of the American Chiropractic Association, Dr. Brennan specializes in athletic performance and injury care, as well as improved mobility and function education.

Dr. Jonathan Thao

Dr. Jonathan Thao

St. Charles

Education: Northwestern Health Sciences

Hometown: Milwaukee, WI

Dr. Jonathan Thao grew up in Milwaukee, WI near the shores of Lake Michigan. He has fond memories of driving along the beautiful lake shore on the way to school, parking at the beach and taking walks along ...the lake, attending Summerfest every year, watching the fireworks over the water - and of course, grabbing a bite at Ma Fischer's diner after a late night out.

What patients appreciate most about Dr. Jonathan is that he takes the time to sit with every patient and listen to what they have to say - how they’re feeling, what their concerns are - before he asks any questions, and always before he performs adjustments. “Whether my patients have a new symptom or condition to inform me about, or just a great story to share, it’s important to me that I connect with them. I love hearing their stories - and sharing my own as well!”

Dr. Jonathan takes a holistic approach to wellness and supports his own wellness with consistent exercise, including continually developing challenging new routines, and going to concerts to decompress, relieve stress and have fun.
