Leadership Team

Tim Rayman


Shaping the culture at Greenleaf Hospitality is especially satisfying for Tim because it allows him to improve the quality of life for his 600+ team members.

Tim has been at Greenleaf Hospitality for 18 years. After two years as Corporate Sales Manager, he became Director of Catering & Convention Services, helping to launch our offsite catering business brand. He served as Director of Hotels until 2018, when he was named CEO for Greenleaf Hospitality Group. Since Greenleaf Hospitality Group ownership purchased the Kalamazoo Country Club, Tim’s responsibilities have expanded to encompass that property as well. Tim attended Western Michigan University.

Tim is on the Board of Directors for Discover Kalamazoo and First Day Shoe Fund. He also serves as a mentor for the First 50 program with Southwest Michigan First.

Being with his family is Tim’s first love. He feels fortunate that he spent many years coaching his kids in baseball, softball, and basketball. If Tim isn’t at home, at a soccer field, or in the gym on a day off, check the golf course. You’re sure to find him there.
