visionary and Founder, NPOC
Marleen created Nurse Practitioner OnCall in 1998, when she recognized the value of providing physicians with a much needed source of relief from the burden of having to take after hours call. While she worked as a Medical Practice Manager in Primary Care and Geriatrics, she collaborated with a Physician and a business executive to create Nurse Practitioner OnCall, the first local call service of its kind. Her attention to detail and high expectation of her expert recruitments have led the telephone triage business to a new level. Her 30-plus years of clinical and healthcare expertise has implemented such programs as the Healthy at Home Program, which offers Primary Care at the home of the elderly and mobility-challenged populations in Eastern Massachusetts. As a practice manager, she took a solo practitioners office with three employees and turned it into a multi-specialty practice with over 20 practitioners and support staff with revenue enhancement exceeding 130% compounded growth annually. She is a graduate of Mount Ida College.
SR. Managing Director
In 2010, Marleen had the continued vision to build her team. Bob, a seasoned CEO, CFO and Global Treasurer, an entrepreneurial “hands on” executive who has demonstrated successful leadership in these roles, was the perfect addition to bring his business acumen and assist in her growth plans. Initially as a consultant, now a integral member/equity player in NPOC, brings a proven track record of accomplishment in start-ups, spin-offs, turnarounds, early to mature stage growth oriented manufacturing and distribution companies, private ($10m-2b) and micro-cap ($100m-3b) public bio-science, educational resources and high tech companies, and healthcare entities. Background includes having constructed new foundations, re-engineering for profitability enhancement and infrastructure development as leading the team by “setting the bar”. Bob is a graduate of Northeastern University and the Harvard Graduate School of Business.
