Ryan Joseph Sullivan

Ryan Joseph Sullivan, 51, passed away unexpectedly on April 15, 2026, near Ruidoso, New Mexico. A resident of both Ruidoso, NM, and Gladwin, MI, Ryan was a man of extraordinary light and an adventurous spirit who found beauty in every corner of the world he explored.

Ryan's thirst for adventure led him to live abroad in Ireland, France, and Mexico-where his true heart resided. He was happiest outdoors, and New Mexico offered him the mountains, trails, and quiet he loved alongside his "lady." He also loved spending time on his kayak on the water in Michigan. Ryan was famous for his radiant smile, and his personal mission was to "be the light that lifts others up," a goal he achieved daily through his kindness and infectious humor.

Ryan graduated from Wauwatosa East High School and went on to graduate from the University of Colorado Boulder. He later completed his MBA in Management Consulting at Grenoble Ecole de Management in Grenoble, France. His gregarious personality and professional integrity led him to a career as the Director of International Business Development for MDF Instruments. Prior to MDF, Ryan was employed by Journey Mexico as Director of Sales and a field guide and Partner in Sullivan Global Consulting.

Ryan is survived by his beloved wife, Michelle (née Dombrowski), and their loyal dog, Daisy, who was his constant companion. He is the dear son of Suzanne Sullivan and was preceded in death by his father, Jerry Sullivan. He was the loving brother to Patrick (Aimee), Michael (David McKone), and Mary Sullivan; and a proud uncle to his nephew Gabriel and nieces Lainey, Iona, and Sula. Ryan leaves behind numerous friends-too many to list-all of whom will remember his smile and laugh.

Following Ryan's formal wishes, his remains will be laid to rest at Gibson Township Cemetery in Bentley, MI. A celebration of his life will follow at the residence of John Doan in Highwood, MI, on July 11th, 2026. An additional informal memorial gathering is planned at the home of Eric Kaye in Milwaukee, WI, on July 18th. Details to follow.

In honor of Ryan's spirit, Michelle asks that you share a kind word or a genuine compliment with a stranger or loved one today. Be the light.
