CO-EXECUTIVE DIRECTOR
JIM STOLLBERG, Co-Executive Director
Jim spent 30 years in business, holding leadership roles in the supply chain automation and management consulting industries. As EVP Global R&D at Dematic, he led their technology transformation, positioning them as a market leader in automation solutions for the world’s top e-commerce, retail, and manufacturing companies. In 2016, after the successful sale of the company to KION, a German public company, Jim assumed the role of EVP, Global Products and Solutions before stepping down in July of 2018.
He began his career in 1988 at Accenture (previously Andersen Consulting) where he led mission critical engagements for his manufacturing and supply chain clients, including Harley-Davidson, Miller Brewing, Johnson Controls and BF Goodrich. After leaving the firm in 1998, he spent one year as VP, Professional Services at EXE Technologies, a supply chain software company, before joining HK Systems, where he held a variety of leadership roles and assisted in the sale of HK Systems to Dematic in 2000.
In 2018, Jim founded Gemini Global Advisors to assist his clients in achieving similar results to what he has delivered throughout his career. His clients include venture capital, private equity and supply chain technology companies. He has served in several board and advisory roles with privately held market leaders, including Shipmonk, Autostore and Covariant.ai.
Like many, Jim first heard of Halftime through the book. It was given to him by a mentor when he was in his late 20’s. He loved it, but found himself committed to achieving “success” above all else. About 25 years later, that same mentor recommended he participate in the Fellows Program, which he did in 2019. It was nothing less than transformational.
Jim holds a Bachelor of Science in Mechanical Engineering from Marquette University and continued his education at INSEAD, where he completed the Global Executive Program. He serves on Marquette’s Supply Chain Advisory Board and volunteers for their Advanced Global Business Leadership program. He previously served on the Supply Chain Advisory board at Georgia Tech.
Jim has a passion for social enterprise and impact investing. He is an avid supporter of Global Brigades, a non-profit that helps to resolve health and economic disparities through sustainable means. He is also a lead investor in Eskala, a micro-finance/micro-equity fund that forms and invests in community-owned banks in Central America. The Stollberg Foundation supports a partial scholarship to first generation Marquette students interested in supply chain studies. The family also supports Compassion International (Thanawit from Thailand and Katarim from Columbia) The Children’s Outing Association (COA), Wounded Warrior Project, Folds of Honor, and the Wisconsin Humane Society.
Jim’s interests include travel (his career took him to a lot of interesting places) and all Wisconsin-based sports (Packers, Brewers, Bucks, Badgers). He is an avid Marquette Basketball fan. He also loves to read (primarily history, biographies and faith-based books) and enjoys the company of his family and friends.
Jim and his wife, Leslie, have been married since 1991 and reside in Brookfield, Wisconsin. They have a son, Justin, attending the University of Wisconsin – Madison studying Industrial Engineering. Their daughter, Lauren, is attending Marquette University studying Business and is a member of the MU Dance Team.

CO-EXECUTIVE DIRECTOR
TOM MCGEHEE, Co-Executive Director
Tom began his career by serving in the Marines for 12 years before moving to Texas, first to work on large outsourcing deals with EDS, then to become a Partner with Ernst & Young Consulting. As a leader in the area of group facilitation and collaborative work, Tom’s work extends to over 25 countries and has carried him from some of the biggest boardrooms in the US, to some of the world’s most innovative churches.
In 2001, Tom left E&Y to start his own company, WaveChanger, a company focused on not only facilitating collaborative work, but also equipping organizations (businesses, ministries, and churches) to Go Faster Together! It was then that God led Tom to Bob Buford, who was not only a mentor (and in many ways a father figure), but he also opened up to Tom through his Halftime and Leadership Network organizations, a world of Kingdom work even beyond the business network that E&Y had created. His work is his passion and his biggest blessing short of his wife and family.
Tom had the privilege of working with Bob Buford and Lloyd Reeb to help launch the Halftime Institute back in 2003. He designed and facilitated the initial materials and sessions and has enjoyed seeing how much that content has evolved into several program offerings today. Tom participated in the Fellows Program in 2020 and has found it meaningful to be back working shoulder to shoulder with his Halftime Family as Co-Executive Director of the Halftime Institute
Tom grew up the son of an Air Force Officer and was born while his father was stationed in Japan. Tom attended Auburn University and became an Officer in the United States Marine Corps after graduation. During his service, Tom commanded two Special Operations Capable Units and served at the Marine Barracks, Washington DC.
Tom and his wife, Elaine, will celebrate 43 years of marriage in June. Elaine has been a spiritual helpmate and a leader while deployed and home. Their biggest challenge came with their oldest son’s 10-year battle with a drug and alcohol addiction. In 2009, he tragically died in a motorcycle accident, but the family was able to see God in the tragedy. Today, their two daughters and younger son are all married, and they have ten grandchildren and counting.

ALYSSA HEFFLEY
MEMBER ENGAGEMENT MANAGER
ALYSSA HEFFLEY, Member Engagement Manager
As the Member Engagement Manager for the Halftime Institute, Alyssa Heffley combines her creativity, strategic top CliftonStrength, and desire to serve others in her day-to-day life.
A native Texan, Alyssa grew up in the DFW area. She left the Lone Star State to attend The University of Alabama (Roll Tide!), where she graduated Summa Cum Laude and earned the distinction of Outstanding Advertising & Public Relations Graduate.
Prior to joining the Halftime Team in January 2017, Alyssa gained varied experience in promotional, marketing, and communications roles – both in the for-profit and non-profit sectors. From creating corporate promotional campaigns, to strategizing volunteer mobilization at a Food Bank, to developing a child sponsorship program for a school in Uganda, Africa, every step has prepared her for serving Halftimers in her sweet spot.
When Alyssa isn’t dreaming up creative ways to help people with smoldering discontent (a key indicator – you’re in Halftime!) find and fulfill their Ephesians 2:10 Calling through Halftime, she can be found leading Young Adults in the Dallas area through Bible Study Fellowship International or looking for a fun spot to enjoy live music.
One of Alyssa’s many favorite verses is Ephesians 3:20-21, “To Him who is able to do exceedingly, abundantly beyond anything that we could ask, pray, or think, according to the power at work within us, to Him be the glory forever and ever.”

CLIENT EXPERIENCE MANAGER
RENI FILBRUN, Client Experience Manager
Reni Filbrun joined the Halftime team in December of 2015. A Grand Prairie, Texas native, Reni grew up in the DFW Metroplex with her parents, Phil and Tanna, and two sisters, Jara and Kali. She adores being a daughter, sister, aunt, and (sometimes excessively) a granddaughter. She graduated from Abilene Christian University in May 2014 with a Bachelor’s Degree in Youth and Family Ministry.
Reni has a heart for ministry, specifically to teen girls, and spent 3 years prior to joining the Halftime Team in Spring, TX serving as the Youth Ministry Intern at Bammel Church of Christ. There are very few things in life that bring Reni more joy than knowing she has affected a teen’s life in a positive way. She learned a love of sports from her father and runs as her main outlet to relax. “Go Cowboys, Go Buckeyes, Adios.”
Her favorite Bible verse is Romans 8:38-39 (with Psalm 46 a very close second), “For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.”
