Our Chiropractors

Dr. Corey Harris

Dr. Corey Harris D.C., PTA - Owner

Braund Street 

Dr. Corey Harris was born and raised in La Crosse, WI, and graduated from Logan High School in 1999. He attended Western Technical College and Viterbo University, where he completed his general studies and played for the Men’s Basketball Team. After his undergraduate studies, he attended North Western Health Sciences University in Bloomington, MN, earning his Doctor of Chiropractic Degree in 2007. Dr. Corey always envisioned coming back to the Coulee Region and serving the community, and in 2011, he opened River City Chiropractic. 

Dr. Corey chose to study Chiropractic because of its natural, safe, and practical approach to dealing with injuries, whether from a sports-related incident or an auto accident; Chiropractic helps in many ways. He also feels strongly about Chiropractic’s medicine-free approach to health, treating the cause of the issue related to pain instead of treating just the symptom. 

Dr. Corey resides in Onalaska with his wife, Katie, and their three children. In his free time, he enjoys adventures with his family, running, golfing, and being active. His active lifestyle motivates him to stay healthy for his family and patients so he can continue to serve and help others live their best, active lives pain-free.

Dr. Logan Andera D.C.

Dr. Logan Andera graduated from Palmer College of Chiropractic in Davenport, IA 2015. Before attending Palmer College of Chiropractic, he completed his undergraduate studies at the University of Northern Iowa, earning a Bachelor’s in Biology. He was born and raised in Cresco, IA, where he was one of six children. Dr. Logan always knew he wanted to work in the medical field and was drawn to more natural health that did not rely on medications. After seeing a Chiropractor during Junior High for aches and pains from playing sports, he realized the power of Chiropractic adjustment. He always felt great afterward! When he is not in the office, Dr. Logan enjoys fishing, hunting, golfing, and spending time with his nieces and nephews. Not only is daily healthy living vital to him, but Dr. Logan loves getting people back to living their lives the way they want. Whether that is being able to work pain-free, golf, or play with their grandkids, he loves hearing about the improvements in daily life that his patients get from Chiropractic care.

Dr. Brett Winchel

Dr. Brett Winchel was born and raised in Tomah, WI, and graduated High School in 1994. He attended undergraduate school at UW-Oshkosh and St. Louis Community College at Meramec. He completed his Doctorate in Chiropractic at Logan College of Chiropractic in Chesterfield, MO 2000. 

Dr. Brett has previously owned offices in St. Charles, MO, Germantown, WI, and Gallatin, TN. As much as he has enjoyed his time in other regions of the country, he is excited to be back in the Coulee Region, assisting the community.

Dr. Brett is married to Sarah and has a son, Hudson. He spends most of his time involved in Hudson’s sports and enjoys hunting and fishing when available. 

Dr. Quinten Kreul D.C.


Dr. Quinten grew up in the small town of Lancaster, WI. After obtaining a Bachelor’s degree in Biology at the University of Wisconsin-Whitewater, Dr.Q graduated from Palmer with his Doctorate of Chiropractic in 2023. After graduation he moved to La Crosse with his girlfriend Maddie. He discovered chiropractic early in life after back pain had prevented him from playing high school football. After a couple of visits to the chiropractor he was able to compete again pain free. Ever since he has found his passion in providing holistic health care for all! In his free time, Quinten enjoys spending time being active outdoors, whether hiking, fishing, or competing in sports of all kinds. Above all, Dr. Q’s mission is to empower anyone to take control of their own health. “I believe Chiropractic is more than the adjustment,  it’s important to arm my patients with the knowledge and ability to manage their own health and symptoms,” says Quinten.
