About Us

The people and the philosophy behind the firm


As Planners, we can quickly evaluate a Client’s present facilities or home, and their overall long-term goals. We can then assist in a preliminary or long term Master Plan or Feasibility Study. We can also advise on modernizations to existing facilities, land purchase, fund raising, and budget-driven phasing for new projects.


As Architects, whether you are looking for a new home or building, or alterations to your existing facilities; we can lead you from concept design, all the way through the construction process…and beyond.
