I grew up in Chilton, Wisconsin, a small town where the proverbial “everybody knows your name” holds true. My dad worked as a transportation manager while my mom had an in home daycare to allow her to spend more time with my two younger brothers, Jon and Justin, and myself. Our house was always full of activity, and I felt like I had an extra eight brothers or sister seach day. I learned to share very quickly, or at least hide my most prized possessions for safe keeping! Piano lessons, marching band, volleyball, basketball, and track involvement kept me on the go throughout high school.

My parents always reinforced that I could do anything I set my mind to, and I dreamed of being a doctor. This dream was reinforced with my own experience of several severe ankle and knee injuries during sports activity and my brother Jon’s diagnosis and treatment of brain cancer at the age of 13. (After a hard battle, his story continues with success as he graduated from college with a double major!)

I attended the University of Wisconsin-La Crosse, studying biology and chemistry with a pre-med focus. Balancing the rigors of marching band, a heavy course load, and waitressing left me run down with chronic sinus infections. I had visited a chiropractor once or twice in high school but never thought of the profession as more than “back doctors.” After being under the care of a great chiropractor for two months, I was infection free, sleeping better, and living with more energy! My curiosity surrounding chiropractic was mounting.

Learning more about chiropractic, I discovered the natural and drug free approach that focuses on restoring balance and health to the master controller of our bodies- the nervous system. This philosophy resonated with me, and I decided to become a chiropractor myself. After graduation from UW-L, I attended Palmer College of Chiropractic in Davenport, Iowa, the Fountainhead of Chiropractic.

I learned from amazing faculty and staff while at Palmer, and my own love of teaching grew. This led me to be a teaching assistant for Physical Diagnosis, Obstetrics and Pediatrics, as well as in the outpatient clinic. I had the opportunity to travel to Vietnam on Clinic Abroad and help provide care for thousands of individuals who otherwise would not have access to care. It was a truly humbling experience to see the poverty of possessions, yet the rich endless spirit of the people! To cap off my Palmer experience, I graduated as a valedictorian as well as earning the Clinic Excellence Award.

Family is extremely important to me, and I was thrilled to find a great place for me to build my practice close to home. My husband and I reside here in Waukesha, and I am honored to serve families of the greater Pewaukee area by providing specific thorough chiropractic care along with the knowledge and information they need to make healthy lifestyle choices.

I grew up in a very small town, Brodhead, Wisconsin. I am one of three children. I have an older sister and I have a younger brother. My parents own a business called Biplane Rides of America; they give airplane rides to adults and children all over the U.S., so my senior project consisted of me learning to fly. I was a very active student in school, where I participated in volleyball, track, student council, and show choir. 

After high school I attended the University of Wisconsin- La Crosse. I majored in Biology and minored in Chemistry. I really wanted to pursue physical therapy there, but a friend peaked my interest in chiropractic. After graduation I decided to make the move to Davenport, Iowa to continue my education at Palmer College of Chiropractic. Palmer was by far the best educational experience of my life; I even went to Brazil on clinic abroad.

After graduating from Palmer, I moved back to La Crosse (where my husband stayed while I attended Palmer) to take an associate position with the chiropractor I interned with. Shortly after that my husband and I decided to move closer to friends and family, and this is what brought us to the Pewaukee area. My husband and I have 3 children; Rowen, Brooks, and Emersyn. We enjoy spending lots of time outdoors, whether that is walking, playing sports, or trying a new park.  I am looking forward to continuing my career at Shepherd Chiropractic Clinic with Dr. Erin and Dr. Dean and serving the surrounding area.

I am originally from the area and grew up in Waukesha. I graduated from Pius XI High School and I have a bachelor’s degree in Biology from Gettysburg College. My Doctorate of Chiropractic degree is from Northwestern Health Sciences University in Bloomington, MN. I feel like my life has come full circle professionally. I have enjoyed returning to practice and serve the community where I was raised.

Animals have always been a passion for me. I originally wanted to be a veterinarian, but realized in college that wasn’t meant to be my path. After finding out about chiropractic for animals, I was intrigued about chiropractic care in general. After touring chiropractic schools, I really resonated with the natural approach to health care. Upon graduating, I took a 220hour post-graduate program for veterinary spinal manipulation (animal chiropractic) at the Healing Oasis in Sturtevant. I currently am an instructor for the same program I completed and help teach both chiropractors and veterinarians. I love being able to adjust every member of the family, including the four legged ones!

Outside of practice, I have a busy family life. My husband, Aaron, and I have one toddler daughter, Harriet. I also have 2 step-kids, Teagan and Kristian, who are in middle and elementary school. I like to run and hike with my family. You’ll find us outdoors as much as possible, as long as the weather allows. We also enjoy watching all the Milwaukee sports teams- we love the Brewers and Bucks.

I am excited to begin my chiropractic career in the community that I have called home for most of my life. I was raised in Oconomowoc Wisconsin with my three younger siblings. Our family was always on the go, as we were all heavily involved in athletics. As a family, we have been a part of the Pewaukee Lake Water-ski team on and off over the past 15 years. In my free time I enjoy golfing, fishing, and waterskiing.

After graduating from Lake Country Lutheran high school in 2015, I earned a degree in biomedical sciences at Concordia University Wisconsin.  At CUW, I continued my athletic career as a track and field athlete and competed in pole vault, long jump, triple jump, and javelin. I worked closely with my coaches and athletic trainers throughout my time at CUW, developing a deeper appreciation for athletics. I chose to pursue a career in chiropractic care to help other athletes like myself but also to help people of all backgrounds to live to their full potential.  I graduated with honors from Palmer College of Chiropractic in October 2022 with an award for academic excellence. I look forward to working with the team at Shepherd Chiropractic Clinic.
