Dean Niewolny spent 23 years in executive roles with three of Wall Street’s largest financial firms, finishing his career in the financial sector as market manager for Wells Fargo Advisors in Chicago, where he oversaw a $100mm market. While in Chicago, he and his wife, Lisa, traveled many times to Africa and, seeing the abject needs of widows and orphans, made life changes that enabled them to get involved, such as helping to complete an orphan home and a hospice home in Durbin, South Africa.

In 2010, Dean left his marketplace career to help more people who, like him, wanted to expand their own first half success and skills into passion and purpose for meeting human needs and making a significant difference. Dean joined the Halftime Institute as Managing Director and in 2011 became Chief Executive Officer. He speaks at events around the world, encouraging business leaders to channel first half achievement into a second half defined by joy, impact and balance.

In 2017, Dean authored his first book, Trade Up. In it, Dean shares candidly about his personal transition into a second half of meaning and significance and the learnings of the Halftime Institute over 20 years of helping marketplace leaders do the same. Trade Up is available for pre-order on,, and Barnes&

Having grown up playing sports—eventually in college and semi-professional baseball—Dean still enjoys coaching his son and attending his games. He and Lisa and their two children live in Southlake, Texas.

“The appetite for significance is at an all time high, yet most people have no idea where or how to identify their gifts and talent—and to connect to their passions. And that’s my love for Halftime. Nothing satisfies more than to help a man or woman say, ‘This is what God has for me to do.’”   — Dean Niewolny, Halftime Institute CEO

Chief Operating Officer

Paul’s first half career was filled with a variety of roles in marketing, sales and operations. He worked for a large, non-profit financial institution as well as a Fortune 250 company where he led the marketing efforts in one of their fastest growing divisions.

As he climbed the corporate ladder, God began tugging at his heart saying He had more for him than success, wealth and a corner office. This started an incredible journey for Paul filled with wild leaps of faith, incredible lessons in humility and a life-changing shift in his perspective.

Paul heard about the Halftime Institute through an alumnus and enrolled and began working with his coach. At first this led him to becoming a certified Halftime Coach to help other marketplace leaders discover their next calling, but he knew God had more for him. A few months later, the opportunity came to join the Halftime Institute team and lead their marketing efforts. This role plus his coaching was the final piece of his Halftime puzzle.

Paul and his wife Maryann have been married more than 25 years and have two grown kids, Drew and Jennica.

“It’s been amazing for me to see God use every single aspect of my first half journey to lead me to a second half of joy and impact.  I now see the “why” behind many things that have happened in my life, and I thank God that He loves me enough to give me just a small glimpse into His plan, purpose and process.”

Primary Spokesperson

Lloyd Reeb is a successful real estate developer and owner of retirement housing who made a mid-life transition, looking for greater meaning, joy and impact in his second half. To his surprise he discovered that he was not alone in this journey and that many talented leaders are longing for midlife renewal.

Lloyd has had the privilege of investing 20 years helping leaders plan their second half. He helped launch the Halftime Institute, a global team that teach, coach and connect successful men and women in pursuit of significance.

In Lloyd’s words, “When all you’ve done or own seems to matter less …and your heart craves more meaning, joy and balance…when something triggers in your mind that you’re entering your second half of life and you’re unsure what your calling is for the next season… you’re in Halftime.”

Lloyd has taken the Halftime message around the world: speaking, teaching and coaching individuals through the journey. As a result, he understands the issues that surround your Halftime in a deep and practical way.

He is the author of From Success to Significance: When the Pursuit of Success Isn’t Enough, which is a road map for this mid-life transition. His book The Second Half: Real stories, Real adventures, Real significance provides compelling evidence that your second half could be the most creative and productive season of your life.

Lloyd and his wife, Linda, have written the book Halftime for Couples. They live in Charlotte, North Carolina. They have three adult children.

“Too many people focus the better part of their lives on the wrong things: the company’s agenda, other peoples’ ideas of success . . . money. Over time, this leads to frustration and emptiness. True freedom comes as a people discover their God-given design and pour themselves into service for others.” –Jeff Spadafora

Director of Admissions

Rhonda spent her first half in education; her own (a Bachelors and Masters from Baylor and a PhD from Fordham University) and helping others with theirs as speaker, lecturer, teacher, and Professor at Dallas Baptist University. She is also an author of a book for parents that encourages reading and writing with children.

The Pittsburg, Texas native met her husband at church where he drew her name from a pool of 500 women to become her secret Valentine. More than 2 decades later, she and Keith have two daughters who are currently attending Oklahoma University.

As our Director of Admissions, many find their Halftime journey begins by interacting with Rhonda. Her nurturing and caring spirit helps people get enrolled into the Halftime Institute.

She is a 2013 Halftime Institute alumna and considers Psalm 86:11 her favorite verse: “Lord, tell me where you want me to go and I will go there. With all my heart, I will praise you.”

“I first read Bob Buford’s book several years ago, but my Halftime really began when my youngest left for college. I knew then I didn’t just want another job, but wanted to give back to God by making a significant impact for His kingdom.”

John Sikkema,
Director of Global Partners

“I have watched many people who are running a thriving business, or who are in the middle of a remarkable career, yet have this vague sense that something is missing; life hasn’t turned out as they’d hoped.  Few things make me happier than seeing others ‘get it’ and make the necessary changes and use the unique Halftime process to discover their life purpose and calling.”

As an accomplished business leader, CEO and the largest shareholder of a national financial planning group and Funds Management company, John successfully sold the two businesses to an Australian top ASX 200 company. He had transformed the small company he started in Tasmania into a successful franchise business with 65 offices across Australia.

Yet, it was his personal transformation in moving his focus from success to significance that remains his most satisfying and rewarding achievement.

John was inspired to bring the Halftime Institute coaching programs to Australia after reading the book ‘Halftime’, visiting Dallas, Texas, and meeting Bob Buford in 2008.

Today, as Director of Halftime Institute’s Global Partners, John is passionate about inspiring and empowering motivated leaders in different countries around the world to become part of the growing Halftime movement, by helping other high capacity leaders to become world changers.

After frequently sharing the story of his own powerful halftime journey, he wrote Enriched: Re-defining Wealth, in which he tells of the harsh lessons he learnt in his pursuit of success; contrasting with the life of impact and adventure he has enjoyed since having a life changing spiritual encounter.

John is also actively involved in the church planting movement, Empart. He regularly takes entrepreneurs, business and community leaders on trips to North India, which is truly a life-changing experience.

John and his wife Sue live near the beaches of Bayside, Melbourne, Australia and have four adult children.

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.”
