While seemingly generic, the quote accurately summarizes Dr. Tyler's passion for dentistry. Establishing Hanover Dental just down the road from his childhood home in Greenfield, Dr. Tyler is looking forward to developing relationships and providing his patients the highest level of personalized and comfortable dental care. 

Outside of the office, Dr. Tyler enjoys traveling, snowboarding, eating good food (#traegering), listening to dental podcasts, and spending quality time with his family and friends. He and his wife Marisa have four children: Bennett, Vince, Vera, and Ingrid.


Dr. Tyler is an alumnus of Rockford High School. He attended the University of Minnesota, where he graduated with an undergraduate degree and his Doctor of Dental Surgery degree. After graduation, Dr. Tyler served as a dentist in the U.S. Navy where he practiced at Marine Corps Recruit Depot Parris Island, South Carolina and Marine Corps Air Station New River, North Carolina. Although he looks young, he has had over five years of military and private practice experience.

Dr. Tyler firmly believes once you stop learning, you start dying, and dedicates his spare time to continuing education. Most recently, he became a fellow in the Academy of General Dentistry (AGD). He is also an associate fellow in the American Academy of Implant Dentistry (AAID). His other awards include: Outstanding Achievement Award from the Academy of Operative Dentistry (AOD), and the Clinical Achievement Award in Endodontics from the American Association of Endodontists (AAE). Dr. Tyler is an active member of the AGD, AAID, 21st Century Study Club, and the Maple Grove Spear Study Club.

Dr. Tyler enjoys all aspects of dentistry, but has a special interest in implants, root canals, and cosmetics. He looks forward to meeting you and helping you improve your oral health and quality of life.
