Mary joined Pinnacle in 2014 as the Office Manager, and is currently the Director of Operations, where she oversees Pinnacle’s learning and development programs: supporting and implementing the firm’s policies and procedures. Mary is a pivotal point in the chain of communication and works with clients and candidates to ensure they have a successful experience from beginning to end.
