Garett Essl and Alex Hammerschlag founded Effectus Group with an understanding that the success of a building project relies heavily on the communication and culture between the Owner, the Architect and Builder. Backed by a core group of talented project managers, Alex and Garrett manage and guide teams toward their greatest built projects.
