History and Experience

Performance Strategies Group, Inc. (PSG) was born in 1990, when Mari Martin, the founding partner, was introduced to a breakthrough assessment system called the Kolbe A™ Index while reading an article in the Wall Street Journal.  She became one of the first consultants worldwide to be trained and certified to work with clients using the full suite of the Kolbe strengths assessment tools.

For 25 years PSG has worked with industry-leading corporations, family-owned businesses, non-profits, ministries, and churches.  The message is the same for all:  We help you accelerate the communication, collaboration, and team-building process to create a welcoming workplace culture where together you can do great work!

As PSG grew, we began introducing the leadership principles of Kolbe from a Biblical perspective to Christian non-profits, businesses, ministries, and church staff.  As a result of that work, PSG came to stand not only for Performance Strategies Group, but also for People Serving God.

PSG has three Kolbe Certified™ Consultants with a total of 45 years of experience who together have helped over 25,000 employees grow more engaged, connected, and successful in their work.  Our team is headquartered in Holland, MI, USA.
