what we do


We have overseen the acquisition and management of several million square feet of real estate investments in the office, industrial, multi-family, and residential land development sectors.

  • We target assets that we consider exceptional opportunities because they are in irreplaceable locations, have historic significance, involve strategic relationships, or have some other compelling characteristic.
  • We create value by improving on existing cash flow and finding ways to create new streams of cash flow.
  • We focus intensely on proactive property and asset management to create value. Our investment successes have been realized largely through disciplined operational management in conjunction with sophisticated financial transactions.
  • Our investment underwriting always includes a downside scenario that enables us to thoroughly assess risk.
  • We self-manage all our investment properties.


We provide strategic advice and representation to a range of clients, including property owners, corporate tenants, and investors.  Services include tenant representation, asset management, project management and portfolio management.

  • Our principals have been actively engaged advising clients in the Philadelphia and surrounding markets for over twenty-five years.
  • We have significant experience in executing sophisticated and complex real estate financings, restructurings, and lease transactions; providing the ability to identify and pursue strategies that less sophisticated brokers/advisors cannot.
  • Through our years of experience, we have developed partnering relationships with other real estate brokers, lenders, appraisers and contractors which enable us to always access the skills and insights needed by our clients.
  • We have extensive experience representing clients in headquarters office lease transactions and providing strategic advice to businesses with multiple locations.
