    High School Diploma from Northridge High School


    I've always had an interest in dental. Every time I went to have my teeth cleaned, it always sparked my interest in what they were using and how the process worked.

    My hobbies are just my kids. I like to spend most of my time with family and close friends. I'm always down to do fun and new things.

    I'm a cool mom and being part of this dental family has been such a great experience. 

  • Tristin Hornvius
    Dental Assistant

    Graduated from Northridge High School and took schooling at Indiana University to become expanded functions.

    I never thought I'd be working in people's mouth as a career. I've always enjoyed going to the dentist and working with the public. I'm working towards becoming an RDA.

    I'm currently engaged and had a son in April of 2018. He is the light of my world and the love of my life.

    I enjoy spending time with my friends and family, shopping, and most of all being a mom.

  • Kelli Besser
    Hygienist

    I have an Associate Degree of Applied Science: Dental Hygiene, and also an Associate Degree of Liberal Arts. I chose to become a RDH because it offers me the ability to help other people. I love the independence it offers and the chance to work one on one with the patients is very rewarding. Also, ever since I was a young girl, I've loved going to the dentist and having a hygiene appointment so it only made sense to pursue a career in dental hygiene.



    My husband, Ryan, and I recently welcomed our first child, a daughter named Hazel. We also have an 11-year-old Yorkie. I am a proud mother, and would love to show you photos when you are the office! I enjoy spending my free time with my family, watching movies, dining out, reading, and being active outdoors.

  • Jamie Ward
    Hygienist

    I graduated from Kalamazoo Valley Community College with an Associate’s Degree in Applied Science. I also am local anesthesia and nitrous oxide certified. I have always been interested in the health field and working with people. I enjoy experiencing the difference one can make on a patient's oral healthcare as well as their overall health, every day.


    My husband Brian and I reside in Sturgis with our children. My son is a freshman and is involved in basketball and baseball. My daughter is in seventh grade and plays tennis. When she is not doing that, she is rocking our house with her guitar. Our new addition to our family is a spaniel/lab dog named Bojangle.


    When we are not at sporting events we enjoy swimming, kayaking, and biking, I am very involved in the community where I am a business partner on the Health Advisory Board for Sturgis Public Schools. I also volunteer for education for Dental Health Mouth and the Annual Juvenile Diabetes Rock Star Party at Headlines.


    As well as a licensed holder in Michigan for Dental Hygiene, I am also licensed in Michigan and Indiana as an Aesthetician.

  • Mary Beth Lancaster
    Registered Dental Hygienist

    I am a graduate of Kalamazoo Valley Community College with an Associate Degree in Dental hygiene and I have worked as a Registered Dental Hygienist for over 31 years. I developed an interest in this field as a high school student, partly because my older brother is a dentist.

    I live in Sturgis with my husband of almost 31 years, Kent. We have two adult children, and an amazing grandson, the joy of our lives.

    As a breast cancer survivor, I have been active in cancer prevention and patient advocacy through the Sturgis Hospital. I started as a Big Pink fundraising group, which provided funds to help with the many costs and challenges of women facing breast cancer here in Sturgis.

    I am an avid crafter and I enjoy working on home improvements, decorating and gardening. I also like to cook and entertain family and friends.

    I've always been interested in keeping my own teeth very clean and having a nice smile.
