To the Kirby Family,
Thank you for sharing Mark with all of us. It is not often we meet someone in life who has the energy, charisma, kindness, passion and love for life as Mark. I met Mark while employed at Kinney Shoes. Mark, Marty and Brian were quite the presence at Kinney and I loved it. They always treated me like family and when you are living away from your own, it does the heart a world of good. I had forever friends. My memories of Mark include his incredible sense of humor, ability to mentor people, the Wolverine or Red Wing banter with the boys (and the mock hockey fights in the back rooms), and his willingness to listen and offer honest advice when you needed it most. I know his family meant everything to him so to all of you I offer my deepest condolences. I hope the memories we all share with you now help heal your hearts in the days to come.

Dear Betsy and family,
There are no words to express the loss of your Dear Mark! My husband and I did not know him as personally as many had. However, by reading the beautiful memories that have been shared on his page,one has to know that Mark was a great person that had it all!
He shared to the fullest his knowing and wonderful attributes of mentoring, playfulness,kindness and love to those he cared for and more. Mark will leave a void in people's heart but rather will leave his rich memories that he gave to his family and friends alike.
Bless you Betsy,Andrea and Robbie!
We are truly thinking of you with love!
Phyllis and Byron Jacobson. ( from Minnesota)

My first day at GNC was in June 2017 at a franchise event. I was introduced to many people. Most were polite and said hello and chatted for 2-3 minutes. When I met Mark, he walked me around and introduced me to everyone I needed to know. He spent the time to really get to know me. He was always like that. Positive....willing to help.... My last conversation with him was in his office sampling product flavors. We were laughing, just like we did most days. I cannot believe he is gone.
I spent the first 13 years after college at Best Buy. The associate satisfaction surveys there had a question that read "Do you have a best friend at work?" I loved that question. I always answered YES- I had a lot of friends back then. I'm not sure what happens as we get older- maybe it's other priorities, maybe we get jaded and become cautious about who we let in- but the list of friends at work shrinks. Mark Kirby was my friend. He was a lot of GNC employees "best friend at work". I miss him.

The many great memories our family shared with Mark will always be treasured.
The moment they purchased a home in Algonquin, IL began our longtime friendship. That home was actually our first home, before we moved across the street. We shared a common love of ice hockey, football and family. Work ethics were a natural. Mark was instrumental helping our daughter Ann, to obtain her first job at Foot Locker. Family free skates at the local ice rink were often shared with Mark, Betsy, my late husband Mike, Ann and our son, Gunner. Mike and Gunner also played hockey. Just cannot express in words how sad we are and pray that the special memories and love that Mark showed all of us will always remain in our hearts.

The Halls,
Ann, Gunner and Donna

Thank you for the one year of the Wyandotte Bears hockey team we shared. May you continue to stop the puck from going in the goal.

There are no words to adequately express our deepest condolences on your loss. Kirby as he was affectionately known at GNC HQ; had a profound impact on everyone he interacted with, including myself. It has been a regular occurrence over the last several days to find groups of people huddled together, sharing happy memories of Mark and where there are certainly tears being shed, we remember him fondly. His impact and friendship will not be forgotten. We will keep you in our thoughts and prayers.

Words cannot express what I am feeling right now. I’m so sad knowing I will never get to talk to you again. I will miss so many things about you. Far too many to list. I ask that you, Mom, and Joey keep an eye on Betsy, Andrea, Robbie, and Dad. Ask God to ease our pain. I will miss you and love you forever. Your little brother Marty

Mark was my first boss at Kinney Shoes back in the late 80's. He made me love retail, showed me how to work hard and built a family at our stores. He made such an impact in my life and who I grew up to be. I attribute all of my successes in my jobs to his teachings. His charm, laughter and smile was just a bonus to what a great teacher, leader and great person he was. I truly considered him my friend. I described Mark to someone as the brother I never had, the father I always wanted and the husband I hoped to have one day. He was for sure the total package and will be greatly missed. May his memory be eternal.
