Alliance is a “boutique” real estate investment and operating company focused on the Eastern United States. We invest in (and sometimes create) properties that create value for our tenants, integrate into the community, and generate superior investment returns for our investors. We operate across a variety of geographic markets and property types, implementing innovative and high-disciplined investment, financing, and operating strategies.  We believe that applying our “hands-on” (and sometimes obsessive) approach leads to our owning properties that offer a combination of price, quality and amenities otherwise unavailable in the marketplace.


Each of the Alliance founders -- Clay Hamlin, III, Jay Shidler, and Richard Previdi -- has over 30 years experience in commercial real estate. They have founded five publicly-traded real estate companies, including Corporate Office Properties Trust (NYSE: OFC) and First Industrial Realty Trust (NYSE: FR). Through their affiliates, collectively they own or have invested in over 2,000 properties comprising over 150 million square feet.

Since its inception in 2008, Alliance HSP has acquired, developed and re-developed over $1 billion of office, industrial, retail, medical office, and residential properties with acquisition prices ranging from $5 million to $125 million.


Our core competencies include repositioning/redevelopment; asset amenitization; bi-furcated financing; and leasing. As regards leasing, we believe leasing often is the most underserved “link” in the asset value creation chain. As such, Alliance has one of the most “hands-on” leasing teams in the country with a multi-decade track record of out-performing local market competition.


Our team of seasoned professionals based in Philadelphia, New York, and South Florida has experience in acquisition, financing, development, leasing, asset management, and reporting.

Alliance is an affiliate of The Shidler Group, one of the nation's leading, privately-held real estate companies (
