Dr. Mark Johnston


Dr. Johnston grew up in Alma, MI and is one of eight children. He spent his college days in New Hampshire, where he graduated from Dartmouth College and later attended dental school in Ann Arbor at the University of Michigan. After graduating in 1985, he moved to the Lansing area to establish his practice.

He was involved in sports during high school and college and currently loves to play golf and fly fish. He is also very active in local, state, and national dental organizations which occupy many of his volunteer hours outside of the office.

Dr. Johnston and his wife Mary attend St. Mary Cathedral in downtown Lansing.


Susie grew up in northern Michigan around Gaylord. After graduating from the dental hygiene program at Lansing Community College, she started raising her children and farming with her husband on their family farm near St. Johns. Now that her kids are older she is happy to be back in the dental office and enjoys brightening her patients’ smiles, comparing hunting trophy photos, and working out on her lunch hour. Often quoted saying, “I come to work for some peace and quiet" Susie is a mother of 5, a mother of six if you count her husband!  


New to our office but not new to dentistry, Nichole has been in the dental field since 2010. She is a chairside assistant and also works in the business office helping patients sort out their dental benefits. Nichole loves to laugh and states that humor keeps her sanity in check.

She has two children that keep her quite busy. She enjoys camping with her family, boxing for exercise, and photography. You can often find her traveling around the state taking nature pictures. She loves the four seasons of Michigan and tries to capture all of them with her camera.


Mary is the senior member of the team, having graduated in the first graduating class in dental hygiene at Lansing Community College. A lifelong resident of Lansing, she probably knows someone in your family or at least a family friend. A true dedicated professional, she loves her craft and was told that she should have gone on to be a dentist but never had time in between working, teaching, and enjoying her many and varied hobbies. She loves to golf, fly fish, quilting, reading, and she may be found at a slot machine once in a while.

When first starting out in hygiene, Mary had a great friend and mentor that showed her how to be a true professional in her important role as a dental hygienist. Mary loves to share her skills when mentoring new graduates in a “pay it forward” manner. Thankfully her hands, wrists, back, and neck have not given her problems during her many years as a valued professional. She continues to work as she loves her patients and may own one of every Apple product out there!
