Treyce Sanderson, DDS

I joined the Waterloo Heights Dental team in June of 2021. I’m originally from Sault Ste. Marie, Michigan. After graduating from Sault Area High School, I earned my Bachelor of Science degree in Kinesiology, Honors College from Michigan State University. I then went on to earn my DDS from the University of Minnesota School of Dentistry.

What first drew me to the dental field was a bicycle accident I experienced at the age of 15: After having two of my teeth avulsed, I had to undergo endodontic treatments, and this was a very impactful for me and wound up being a very cool experience. Some of the things that I enjoy most about dentistry are the ability to work with my hands and the opportunity to help people, which I’m very passionate about.

Since joining our practice, I’ve contributed in a number of meaningful ways. I’ve brought a great deal of knowledge about new technology and techniques in dentistry. Additionally, I’m a team player and a hard worker who always works to ensure that our office is providing top-notch care for our patients. Having grown up in a small rural community, I appreciate the strong sense of community that West Salem has, and I look forward to providing our area with high-quality dental care in an enjoyable and welcoming setting.

Outside of the office, I like to hunt, fish, hike, and enjoy any outdoor activity. I always have my truck loaded down with gear for any opportunity for an adventure. I also enjoy cooking: I recently got a pellet grill and am always looking for new recipes to try. I’m very excited to be here and to be part of the team at Waterloo Heights. I look forward to meeting you in the office soon!

Mary Jo

Registered Dental Hygienist

I have been a dental hygienist for almost 40 years and have been a member of the team at Waterloo Heights Dental for over 30. I was born and raised in La Crosse and graduated from the University of Minnesota in 1976. I’ve received advanced training and certifications in laser dentistry as well as the BaleDoneen Preceptorship.

The best part of this job for me is helping people. I love getting to know my patients of all ages and helping them achieve health and wellness. I have witnessed many changes in the dental industry over the last 30 years and I love to see the advancements in treatments and technologies that allow us to provide even better patient care. I truly love helping people.

My husband, Mike, and I have three grown children – Joan who is also a dental hygienist, Maggie who is a medical transcriptionist, and Dan who is a mountain enthusiast for Yetti, Inc. I have enjoyed watching my children grow and become parents themselves, and I now have five beautiful grandchildren whom I love spending time with.

In my free time, I enjoy reading, gardening, traveling, practicing yoga, and working on my singing career with my band Studebaker 7.  I thoroughly enjoy working for Waterloo Heights and embracing new challenges every day!

Registered Dental Hygienist

I have been a dental hygienist for many years and have been with the team at Waterloo Heights Dental since 2000.  I grew up in Holmen, moved to West Salem in high school, and currently live in Bangor. I received my associate’s degree in dental hygiene from Riverland Technical College in 1995, and my bachelor’s degree in dental hygiene from Minnesota State in 2010. I am certified in local anesthesia, laser dentistry, and have achieved BaleDoneen Preceptorship relating to preventive dentistry and cardiology.

The best part of this job for me is helping people overcome their dental obstacles, fears, and concerns. I love being able to help patients achieve healthy smiles and overall health. I truly value working with such an exceptional team and feel that continuing education and getting to personally know the patients are key to providing the best overall care.

My husband, Kevin, and I have three children – Lindsey, Travis, and Kelsey – and three grandchildren – Declan, Ryleigh, and Norah. When I’m not helping patients in the office, I enjoy spending time with my family and friends, gardening, canning, reading, and traveling.

Registered Dental Hygienist

I have been with Waterloo Heights Dental since the year 2012. I started with the team as a Dental Assistant. After 4 years working as a Dental Assistant, I decided to advance and further my career. In 2018, I graduated from Chippewa Valley Technical College with my Dental Hygiene degree. During my schooling I received valuable education and advanced training in local anesthesia, nitrous oxide, and laser bacterial reduction. My favorite part of this job is providing valuable care and education while establishing trusting relationships with patients.

I am originally from Rockland and now reside in Bangor with my husband, Andrew; my step daughter, Niya; and our dog, Ruger. When not caring for patients, I love to travel, hike, and spend time with family and friends.



Dental Assistant

I have over 20 years of experience in dentistry and have been a dental assistant at Waterloo Heights Dental for over a decade. I am a hometown girl, born and raised right here in West Salem! I received my dental assisting education from Western Technical College (WWTC) in 1990, and have additional training in CPR and basic life support.

For me, the best part of this job is meeting new people and changing lives, whether it’s helping with a simple filling or a whole new smile. When someone smiles for the first time in a long time because of our care, it is truly a priceless feeling that brings tears to my eyes. I strive to make every dental experience a good one. I thoroughly explain what to expect and what your dental needs are, and help you have a relaxed and comfortable experience.

My husband, Paul, and I have been married for over 20 years, and we have three children – Justin, Jayden and Jarron. I have loved watching them in all their activities including baseball, choir, band, and theatre. When I’m not at the office helping patients, I enjoy walking my dog, Harley, reading, and spending time with family and friends.

Dental Assistant

I joined the Waterloo Heights Dental team in the fall of 2021. I graduated from Southwest Technical College in Fennimore for the Dental Assisting program in 2018. I’m CPR certified. I’m also working on becoming a dental hygienist. Something that has made me enjoy working in the dental field is knowing that I help bring back the confidence to smile again in some of the patients I’ve seen, after they haven’t truly smiled in months. Plus, teeth are unique and are the first things I notice in people. One thing I like about Waterloo Heights Dental is the variety of services we offer.

I’m originally from Westby. I grew up on a small hobby farm where we had calves, chickens, turkeys, and pheasants. I am currently still located in the Westby area where I live with my boyfriend, Lukas; my yellow lab, Keno; and my kitten, Asher. When I’m not at work, I love to do various types of hunting with Keno, ski, adventure in the outdoors, and sometimes travel.

Dental Assistant

Having grown up in Onalaska, I have called the La Crosse area home my whole life. After high school, I earned my degree in dental assisting from Western Technical College. The main reasons why I chose to enter the dental field are my love of helping people and my desire to help them have the healthiest smile and the best experience while getting it. I always strive to bring a positive attitude to work, and I truly enjoy making connections with patients. The other thing I love about working at Waterloo Heights is our amazing team, who have fun while providing amazing dental care.

Outside of work, I enjoy spending time with my boyfriend, our dog, and our cat. Some of my favorite activities are traveling, hiking, crafting, and hanging out with friends and family.
