Cynthia S. Cornell-Trobeck

Cynthia (Cyndi) Sue Cornell-Trobeck passed away at the age of 63 on the morning of Monday, March 14, 2022, after a brief and abrupt battle with Creutzfeldt-Jakob Disease. Cyndi was an incredible wife, mother, grandmother, daughter, sister, aunt, cousin, and friend. She will be greatly missed but her impact on the people who knew her will be felt for years to come.

Cyndi was born in Kalamazoo on October 5, 1958, to James and Sue Cornell. She spent her childhood years in Otsego, Michigan alongside her two younger siblings, Catherine, and Gregory. She graduated from Otsego High School in 1977 and from Western Michigan University in 1982. She went on to get her Master of Business from Davenport University in 2015. She met her husband and “sweet Baboo,” Gary at a singles group through their church in Springfield, Illinois and got married in 1984. Before having children of her own, when she got married, Cyndi became a bonus-mom to Tracie and Eric and enjoyed taking them on vacations and spending time as a family. This was a role that she always enjoyed and took pride in. Eventually, Cyndi and Gary had three sons of their own (Derek, Anthony and Ethan) and raised them in Otsego alongside many of her family and friends.

Cyndi had an incredible impact on her family but also on her community. Cyndi was the first woman mayor of Otsego, Michigan when she was elected in 2016 and remained in office until her death. Cyndi was involved in numerous local institutions. She taught finance classes at Greater-Kalamazoo Real Estate Association, was on the DDA/Main Street Board, taught Sunday School at Otsego United Methodist Church, and served on the Board of the Otsego Rotary Club and Christian Neighbors. Most of her career involved banking and finance as she was employed by 5/3 Bank as a manager for 19 years. Most recently, she was a real-estate agent with Cornell & Associates.

She loved spending time in nature, and frequently explored the beautiful beaches and lakes in Michigan with her husband. She loved reading, crafting, shopping, and going wine tasting with her sister and mother. Of all these accolades and accomplishments, Cyndi most treasured spending time with her family, husband, children, and grand babies. As she would often say, “her grandbabies are the sprinkles on top of life.” Her love of God, her love for her family, and her love and joy for life itself have left behind an incredible legacy.

Cyndi is survived by her husband Gary, sons Derek (Amber) Trobeck of Decatur, Indiana, Anthony (Emma) Trobeck of Kalamazoo, Michigan, and Ethan (Reva) Trobeck of Otsego, Michigan, bonus-kids Tracie Wills of Lithia Springs, Georgia and Eric Trobeck of Litchfield, Illinois, grandchildren Harper, Annie, Rory, Savannah, Brenden, Emery and Dawson, parents Jim and Sue Cornell, brother Greg (Marcia) Cornell, sister Cathy (Gerry) Boik, along with many nieces, nephews and cousins.

Friends may visit with Cyndi’s family from 4-8 PM, Friday, March 18, 2022, at the Winkel Funeral Home, Otsego.

A funeral service will be held at 11:00 A.M., Saturday, March 19, 2022 at the Otsego High School Auditorium with Pastor Joe Shaler officiating.

Cremation will follow.

Burial of ashes will take place at Mountain Home Cemetery at a later time.

In lieu of flowers contributions in memory of Cyndi may be made to

Cyndi’s Family

List any adjective to describe this amazing woman. We’ll never run out and each will be accurate.

Without consciously trying, she said all the right things at the right time with the right physical accompaniment.

She functioned in harmony with the forces surrounding her.

Cyndi had the rare intangible quality the French call “savoir faire” for which there is no true English translation.

I already miss her like “CRAZY”.

I doubt you’d recognize me in person, but my husband & I are members of OUM. We’ve followed your family’s events on FB and your family’s tragic medical journey with beautiful Cindi. We are friends with the Cornells through neighborhood shin-digs & the Blues Association. Obviously, we know you better than you know us.

That said, we offer our prayers and love to your loving family. Cindi deserved the devotion you provided her so beautifully!

Gary, you provided us timely and strong information, and I know I would love to hear a family member singing to me as your son did to Cindi. ❤️So impressive.

Bless Cindi as her soul reaches Heaven. I’ve never witnessed a family handling this heartbreaking situation with such Grace and Dignity.

Much love, The Massingills

It’s just not easy when you lose someone to something so rare, so quickly and way before her time. Cyndi was an inspiration to many, a light in the community, I personally considered her a friend. She touch our entire family and I am so glad that she played a role in our kids life too. To all of you, Gary, Derek, Anthony and Ethan and the Cornell family, hold strong to your memories, listen for her voice, look for the signs that she is watching over you. She is missed, she is safe, she is whole again. The Siegel Family sends you all prayers of strength and acceptance as you go through this difficult time.

Cyndi was more than my realtor, she became my friend. I was so impressed with her knowledge, but more importantly, her heart. It was apparent from our conversations how much she loved her family. I only knew her for a short time, but she made a lasting imprint on my heart and mind. I hear Cyndi telling us to live life to the fullest. May she rest in eternal peace with God and His angels.

Our deepest sympathies to you all. Cyndi was a true joy to know and could light up any room. I always appreciated her sense of humor and ability to connect with and engage others in conversation. Cyndi was a “go to” for me when I may need a sub for my class – and a pleasure to know outside of work. Her legacy lives on in you all – praying for comfort and support to you all. She will be missed dearly.

I’m so sorry for your loss.

I knew Cyndi from our teen years at school, I loved her sense of humor, she was a joy to be around.

May God comfort you during this difficult time.

I was shocked and saddened to hear of Cyndi’s passing. I met her while with Fifth Third. I always enjoyed when she’d visit Saugatuck and our paths would cross. She had my respect and admiration. I was so happy for Otsego when she was elected mayor as I knew her leadership would be great. I will miss her smile, great laugh, and genuine interest in what was happening in my life.

My thoughts and prayers are with Gary and her family . May they experience the peace that Jesus offers as they move forward. I know Cyndi knew and loved Jesus and rejoice that we will meet again.
