Koleman Karleski

Principal Owner

Koleman began his 20 years of playing competitive baseball on the tee-ball diamonds of his native Pittsburgh. From those early days swinging for the bleachers, Koleman developed his life-long passion for diamond sports with career highlights including two trips to the U.S. Olympic Festival, Mizuno’s All-American team, and playing collegiate baseball at Princeton University.

Koleman’s fierce competitive spirit and success on the ballfields and in the classroom prepared him for a career as a venture capitalist, working closely with inspiring entrepreneurs to bring new business ideas to life. Koleman has spent the past 25 years working with dozens of entrepreneurs to build enduring, game changing businesses.

These days, Koleman takes great pleasure and pride in supporting his daughter, Cosi, as she competes on and off the field – mastering the slopes, water, hardcourt, and tumbling mats.  Koleman knows first hand how these activities have boosted his daughter’s confidence and self esteem, and is excited to be involved in U.S. Fastpitch Open’s efforts to do they same for many other talented girls and young women.
