Jeff has been designing and building projects for clients for over 30 years, having worked on a range of exciting and beautiful projects. 

The overall design-build process is very rewarding, yet also very complicated, with hundreds of factors involved. 

It is important to select an architect and general contractor who has the experience, vision and talent to manage the project from conception to completion and successfully deliver the project with superior results.
