Greg Wood


As someone who thrives on interacting with people, Gregory (Greg) P. Wood couldn’t have made a better career choice. Greg, who launched his current practice in 2001, still gets excited when he reflects on the professional path he has taken. “I love my work so much, I chose this career not once, but twice!” he laughs.

After graduating from Oklahoma State with a degree in business, Greg started out as a stockbroker, and then took a detour in medical sales for a few years while he established his family. A chance encounter with a college acquaintance introduced him to the need to plan for his own financial future. Before long, he was being recruited back into the financial services business.


“I re-entered this business at a perfect time,” says Greg. “Many of my peers had developing careers, they were starting businesses, or had growing families. All of these are opportunities for us as financial advisors to provide real value to clients.” More importantly, it gave Greg the chance to do what he enjoys most: to engage with people in a very meaningful and personal way.

Today, Greg’s practice focuses almost exclusively on risk management. He specializes in estate planning, business planning, and executive compensation plans. As a partner of the Catalyst Group, he takes pride in the firm’s capacity to service clients’ end-to-end needs – from investments to protection strategies, including health insurance. “Our team approach serves our clients well, and ensures that we direct the right talent to address specific areas of need,” he says.

Outside of work, Greg is an avid golfer and personal fitness enthusiast. He and his wife, Julie, are parents to three children. They reside in Tulsa, and are active members of Life Church.

Ken Hirshey


Mr. Hirshey is a registered Professional Engineer. He holds a Bachelor of Science in Civil Engineering from the University of Arkansas and a Master of Science in Civil Engineering from the University of Texas at Arlington where he piloted the initial Management of Technology MBA curriculum. Mr. Hirshey currently serves as Chairman of Cyntergy , a full-service architectural/engineering firm. Founded by Mr. Hirshey in 1997, Cyntergy provides all engineering disciplines and architecture in-house with a staff of over 115 professionals, which makes it the largest AEC firm in the state of Oklahoma.

Mr. Hirshey serves on several boards including Christian outreach organizations such as Young Life, Influencers, Operation22MST, and Tulsa Children’s Museum.   The impact that Influencers and the Journey have is beyond words.  This journey to true discipleship and understanding of the character of God reveals His heart and true nature and what He intends for each of us to model and reflect.  We were created in His image and we have the heart of God inside us.  As we abide in Him he transforms our heart to what He intended us to be.  Because of this, we can be influencing others in a genuine and natural way wherever God has placed us in the marketplace. 

Rich Love

Ryan Griesmer


I am originally from Missouri but have called Tulsa home since 1998. Married to Kacy for over 20 years and have 3 children: Madison, Luke, and Roxie. After 20 years of working for an Adhesive and Equipment distributor, I made a career change and now sell Engineered Suspensions for Ridewell Corporation.  God’s timing is always perfect and it led me to go through the Journey in 2009. It was the right time for me to start seeking Him in my daily walk. God continues to surround me with incredible men in my life. Men that I can lean on and lock arms with during the battles that we face daily. I am honored and excited to be a part of the Influencers Tulsa Board. I am constantly amazed at how God is using us to help hungry men seek a personal, abiding relationship with our heavenly Father!
