"Dealing with everyone at Oz Contracting has been an absolute pleasure! Our first project was remodeling a bathroom.

Our upcoming fourth project with Oz will be converting a bedroom into a primary bathroom and constructing a walk-in closet. Uzi, the owner, is the numbers man and has been wonderful to work with. He helps with the layout and gives meaningful suggestions to complement our needs. Lori, the designer, is very creative and has been able to make our vision become a reality. We value her opinion, which usually winds up being our choice. Our foreman Mike is fantastic. He's on the jobsite regularly and addresses any concerns immediately to our satisfaction.
