Upon first introduction at her interview, she was drawn to the staff and, upon hire, began to train and learn all she could about the treatments and about living a lifestyle to promote health and healing. Seeing patients arrive in pain and, within a week, return with happy tears has been the most rewarding career experience she has ever had. She is the bubbly, smiling face behind the front desk counter, waiting to greet patients when they arrive. Cindy is a former stay-at-home mom who joined the team with an open mind and positive attitude. The birth of her three children has sent her on a healthier track in life.

Sue Perovich

Sue has a lifelong passion for cooking and eating healthy. Raised on a dairy farm and nourished as a child with the bounty of her mother’s extra-large vegetable garden, she is a firm believer that what you eat is a huge contributor to your health. She loved to read cookbooks as a child and still enjoys cooking as a hobby. The recipes she uses these days are usually adapted to make them keto and/or paleo-friendly.

Sue’s path to functional medicine was paved as she encountered health challenges within her own family. She first sought out traditional medical care which included the use of medication. When one medication didn’t work, another was added to the mix, causing extreme side effects. She asked the physician if he felt her son’s diet might be contributing to his health problems and was told, probably not. Following through on her hunch, however, she found research and resources that helped her discover natural approaches to healing and balancing the body. It all made so much more sense. She put that approach into action with spectacular results for her son.

Now, as a patient care coordinator, Sue helps patients at Functional Medicine Center of MN with diet and lifestyle changes to work in tandem with treatments to accelerate their own healing.

Maudie R. Louisiana, DC

Dr. Maudie Louisiana, DC, majored in Biochemistry and Molecular Biology with minors in chemistry and math at The University of Minnesota, Duluth. She studied at Northwestern Health Sciences University, where she earned her Doctor of Chiropractic Degree. She also studied endocrinology and bioidentical hormones, Sacro Occipital Technique with SOTO-USA, and is certified in QST. She is an advanced practitioner of QNRT.

Dr. Louisiana first experienced the healing benefits of chiropractic care after she developed severe headaches while in college. She was so impressed with the extreme improvement in her health that she decided to go to chiropractic school. Fast forward several years, she learned that her first pregnancy results included the revelation that she was carrying triplets!

She intently looked for direction from the obstetrics field for how to support herself and her babies through this special need period, but her quest for guidance fell short. Dr. Louisiana and Dr. DeYoung applied all their knowledge and protocols for supporting health with nutritious food, a healthy lifestyle, and stress management. Their three healthy girls were delivered at 32 weeks. Now in their formative years, the triplets have robust immune systems and rarely require a doctor’s visit. Dr. Maudie embraces the provisions to allow bodies to heal themselves, especially with her family.

She also uses her specialized knowledge to help female patients in the reproductive and post-reproductive stages of life. Another area of specialty is to provide protocols to reduce post-injury and post-surgical pain caused by scarring. Her approach has been the key to solving long term chronic pain issues for patients that were not ameliorated even after years of attempted conventional treatments or medications.
