Susan DeGuire
Sr. Vice President
Susan grew up in Nashua, New Hampshire, and received a Bachelor of Science in business administration from Plymouth State College in Plymouth, New Hampshire. After leading the sales division as the VP of Sales and driving business for CornerStone Staffing for 20 years, she was asked to open CornerStone Medical.
This opportunity hit a personal note for Susan because her mother was a recovery room nurse in Nashua. She learned from her mother the demands of being a nurse and the dedication a healthcare professional has to their patients.
That is why Susan and her team of medical staffing professionals are committed to finding the right positions and the best career opportunities to help healthcare professionals prosper and support their families. The Cornerstone Medical team listens to their customers closely and aligns themselves with them to provide the right employee each and every time.
