Professional Journey

Allen started out in fundraising at a social services agency in the Boston area. She then moved into healthcare revenue cycle management, the work of getting healthcare services billed, coded, claimed and paid, and has stayed in that field for more than 25 years. Her first revenue cycle job was as an account manager at GE Healthcare. SSI’s materials also list McKesson Corporation and Harvard Medical Faculty Physicians among her earlier employers.

She later held operating roles at provider organisations. She was vice president of revenue cycle at Somnia Anesthesia, Inc., and chief executive of Physicians Professional Services in Medford, Massachusetts. SSI’s appointment announcement credits her with helping that business add more than $3 million per month in revenue during her first year. Alongside that work she taught at Southern New Hampshire University as an adjunct professor of healthcare administration, with courses covering healthcare finance, leadership, ethics and law, project management and Lean Six Sigma process improvement.

The SSI Group named her president and CEO in February 2020. She replaced Jimmy Lyons, who had been with the company for 23 years. At the time SSI had been ranked No. 1 by KLAS for revenue cycle claims management in 2020. In announcing the appointment, Allen singled out SSI’s claims analytics, which uses artificial intelligence to predict when a claim payment will arrive.

That emphasis has carried through her tenure. In June 2026 SSI announced its ARC (Autonomous Revenue Core) product, first deployed at Springhill Medical Center, and Allen presented on autonomous healthcare revenue at the HFMA Annual Conference with Springhill’s executive director of revenue integrity. SSI’s current leadership page lists her as Chief Executive Officer and Jennifer Strahan as President.
