Dr. Mark Hostetler, a beloved husband, father, grandfather, dentist, and friend, passed away on August 19, 2025, at the age of 65. His life was defined by devotion to his family, commitment to his profession, and a love of the communities that shaped him.
Mark was born on December 29, 1959, in South Bend, Indiana, to Robert J. Hostetler and Agnes Mae (McMahon) Hostetler. He grew up in Ann Arbor, Michigan, where he formed lifelong bonds with the group of neighborhood friends affectionately known as the “Middleton Drive Boys.” Together, they shared countless adventures, laughs, and memories that Mark cherished throughout his life.
A gifted student and athlete, Mark excelled in cross country at Huron High School before continuing his academic and athletic journey at Hope College in 1978 as part of the cross-country team. He later transferred to the University of Michigan, where he earned his undergraduate degree in 1981 and his Doctor of Dental Surgery in 1985. His passion for education and athletics remained with him throughout his life, and he was a proud and loyal Wolverine fan, especially enjoying Michigan football and basketball.
For over 40 years, Mark dedicated himself to the practice of dentistry, where his skill, professionalism, and compassion left a lasting impression on his patients and colleagues. He was an active member of the American Dental Association, the Michigan Dental Association, and the Central District Dental Society. His leadership was widely recognized, as he served more than two decades on the state peer review committee—six of those years as chair—and contributed nine years on the Ethics Committee, where he served as chair for two years. His legacy within the profession is marked by integrity, mentorship, and a commitment to excellence.
Mark’s greatest joy, however, was his family. He shared a beautiful 36-year marriage with his wife, Alicia, building a life rich in love, travel, and shared friendships. Together, they raised four sons—Benjamin, Michael (Allison Maebius), Alexander (Alexandra), and Stephen (Courtney McKown)—each of whom brought him immense pride. Mark was a hands-on father, actively supporting his children’s activities, coaching basketball, baseball, and soccer, and later becoming a tireless volunteer with the DeWitt Band Boosters for more than a decade.
Family gatherings often found Mark at the puzzle table, relaxing with a book, chatting with his “bourbon buddy” Dan, or simply watching the sun set over Lake Michigan. In recent years, his most treasured role was that of grandfather to his grandson, George, whose presence filled him with joy. He never missed an opportunity to share photos and stories about his beloved grandchild.
Mark is survived by his wife, Alicia; his sons and daughters-in-law; his siblings, Lori Hostetler (Michael Petersen) and Dr. Robert Hostetler (Nancy); in-laws Dr. George and Mary Ann Mansour, and brother-in-law Philip Mansour. He also leaves behind his nieces, Sarah, Ellia, and Corinne, who held a special place in his heart, as well as his cherished uncle, Joseph McMahon, and other brothers, Chris, Doug, and Jim.
He was preceded in death by his parents, Robert and Mae Hostetler. Mark was deeply grateful for his longtime friend, mentor, and business partner, Dr. William Schoonover, whose support and camaraderie meant so much to him throughout his career.
Mark’s life was one of service, kindness, and love. His legacy will live on in his family, his profession, and the many lives he touched.
In lieu of flowers, the family requests that memorial contributions be made to Holy Trinity Greek Orthodox Church in care of the Altar Boy Fund, honoring Mark’s faith and devotion to his community.
