About Us


Lake Superior Chiropractic is a chiropractic offering proactive care. Being proactive is essential in maintaining good health. That's why we focus so much on it here at Lake Superior Chiropractic. We want you to be your best self, and chiropractic care can help with that.


Dr. Carl Miller is a lifelong community member, and is always trying to improve the lives around him, whether through participating in various organizations over the years, volunteering, or holding drives at the office. He is happily married to his wife, Sue, and together they love spending time with their four children, three grandchildren, two son in laws, two dogs, and two grandanimals, especially in the outdoors. Dr. Miller graduated from Northwestern College of Chiropractic in July of 1989, completed his internship and post-graduate practice at Amsden Ridge Chiropractic Office in Bloomington, MN, completed the Spinal Trauma Certificate Program at Northwestern College of Chiropractic, and purchased Lake Superior Chiropractic in November of 1989, where he's been ever since.

Darla Williams has a passion for natural health, and works hard to ensure you will receive the best massage therapy catered to your needs. Whether you're in need of a relaxing back massage after a busy week, or need massage therapy targeted at a specific area, Darla will make sure you leave feelings a million times better than when you arrived. Outside of work, Darla lives in the country, where she enjoys the quiet life with her cats and little red hen, reading, and drinking coffee. She received her certificate/diploma at DBU with stunning grades.

Sue Miller has been rooted in Superior since her family moved here in the 80s, and is happily married to Carl, who she helps run the office with. Sue enjoys spending lots of time with her four children, three grandkids, two son in laws, two dogs, one granddog, and one grandkitty (it's a full house every Thanksgiving!). You can also find her within 100 feet of every "Estate Sale Here" sign, hunting for antiques! Sue received her degree in education from UW-Superior, and will occasionally substitute teach for the school district of Superior. 



Senia Swanson has been working in the office ever since her dad, Dr. Miller, could put her to work. Over the years, she's developed a talent for technical writing and copywriting, and since then has worked with numerous businesses and companies of all sizes and industries. She enjoys reading, binge watching shows with her husband, boating, fishing, camping, and walking with her dog, Dafne. She is currently pursuing two Bachelor degrees in Writing (B.A.) and Music Performance (B.M.; Violin) at UW-Superior, and will be graduating May of 2020.

Felicia Swenson is another one of Dr. Miller's daughters, and has been working at the office for over 10 years. She's been a dedicated secretary here, but since becoming a mom to three perfect kiddos, Bella, Lilia, and Oliver, she hasn't been here quite as much. In her spare time, she enjoys reading, playing with her kids, and going on long walks in the neighborhood. Felicia graduated from UW-Superior with a degree in elementary education in 2014.




Almost 30 years ago, Dr. Miller had a dream to open up a small chiropractic clinic here in humble East End Superior. Fast forward to today, and he has been heavily involved in the community, alongside his wife, helping put on East End Family Fun Day, from which he is now retired from, and improving the community through various drives for organizations such as the local humane society and CASDA. 

We are lucky to have such an incredible team. Over the past few years, we have become almost an office family, working together to bring the best care for our patients. We look forward to the years to come!
