Greysteel Expands Healthcare Investment Sales Team with Two Advisors in Pennsylvania

Greysteel announced that Bart Tantillo and Christina Trevenen will join the firm’s healthcare investment sales practice as advisors based in Pennsylvania.

Tantillo and Trevenen will support sourcing and executing investment sales and capital markets assignments for medical office properties across Pennsylvania. Their addition expands Greysteel’s capacity to advise private, middle-market, and institutional clients on value-creation strategies in the healthcare real estate sector.
