The SM+P offices in Baltimore, Maryland

History of our firm

In 1982, Walter Schamu & Associates moved into Baltimore's Federal Hill neighborhood, and began a legacy of unique, revered architecture, starting out with a focus on residential work.

Through the 1980s, the firm continued to expand and bring in new, exciting work. 1984 saw a new location for the growing business and the firm found work in historic preservation, renovation, rehabilitation and adaptive use. The following year, Anthony Machowski parterned with the firm, bringing with him work from the healthcare, education and research industries.

During the 90’s, the firm expanded even more, with Victor Greco, AIA, opening up a satellite office in Wheeling, West Virginia. The office provided academic, healthcare, institutional, commercial and residential design for clients in West Virginia, western Maryland, and Ohio.

Into the 2000’s, the renamed Schamu Machowski Greco (SMG) Architects picked up some of their most notable work, including renovations to the Hippodrome Theater and the rebuilding of the B&O Railroad Museum, both in 2004. The firm continued to gain success with a myriad of clients and projects garnering multiple recognitions.

On February 26, 2014, exactly 32 years after Walter Schamu & Associates opened their doors, SMG announced their renaming and rebranding of the company, and welcome Charles Patterson on as partner. SM+P continues in the tradition of its former incarnates as a firm of excellence, embracing a future with new, exciting clients and projects.
