Leslie Ehm and Joan McArthur

27 Marbles Training is partners Joan McArthur and Leslie Ehm.


"As advertising industry professionals, we had personally experienced training sessions that had no relevance or insight into the very real challenges we and our teams and our clients were facing day-to-day. With our shared expertise, love for communicating ideas and passion for coaching, we joined forces to develop workshops that focused solely on the high stakes issues we knew first hand could ultimately lead to the success or failure of agencies, client-side marketing teams, and creative work in general."
