Board of directors

Gary Crane, PCC
Meet Gary Crane

Gary’s initial career was in senior level finance for federal government agencies and private companies, where he had a strong interest in leadership. He credits his work with an executive coach as transforming him into the type of leader he wanted to be. As he studied more and coached his own staff, he grew so interested that he took an early retirement and began coaching full time.

He joined the ICF Metro DC Chapter in 2015 to network within his new métier. As an active member, he soon reached out to the Board and made use of his accounting skills by serving as Treasurer. He now serves as the President, and looks forward to helping lead ICF Metro DC in its quest to help members maximize their effectiveness through accreditation, continuing education, and community. 


Gary earned coaching certification from Georgetown University, and maintains International Coaching Foundation Professional Certified Coach (PCC) certification and Hogan Assessment certification.

Gary specializes in Leadership Coaching as well as strategic planning and management consulting, primarily in the Federal and higher education sectors. He authors a leadership blog, Leading by Example

"To the extent your employees aren’t succeeding, you have to look in the mirror. Coaching helps identify and overcome blind spots and elevate your leadership game."

Marlene Thomas, PCC
President  Elect
Meet Marlene Thomas

When Marlene was still working as a Senior Executive Service (SES) executive, her daughter told her she should be a coach. When she retired from a career as Associate Administrator and CFO, training, and finance, that’s exactly what she did. As President and CEO of Thomas Management Consulting, her first big job was a trial by fire, and she realized she wanted more formal training as a coach. Since then, she has continually sought out additional education and training, and calls herself a lifelong learner. 

Marlene became a member of the Metro DC Chapter in 2016 and soon joined the Board. Knowing that coaching is a somewhat solitary profession, she sought the community provided by working with other coaches. She also wanted to see the Board become more diverse and reflective of its membership.  


Marlene earned a coaching certification from the Coach’s Training Institute (CTI). She is also a Certified Professional Co-Active Coach (CPCC), and is an International Coaching Federation Professional Certified Coach (PCC).  

Coaching Focus

Marlene partners with small-to medium-sized business and non-profit organizations to unlock the potential of individuals and teams. She also works with a lot military persons and executives who are going through career transitions.
