He produces exquisite work from a pragmatic approach. He is one of few principal architects with whom I have worked that hand draws at project meetings to problem solve and create designs as a result of Client's wishes. He does this so skillfully and \[it appears\] effortlessly. Additionally, his knowledge of construction means and methods is as impressive as his comprehension of building costs, which is important to bring dreams to fruition while managing the Client's budget expectations. Rob is the "Renaissance Man" of architecture in my experience. > > Steve Ferqueron > Vice President > JD GROUP, INC. **★★★★★ — Matt Dugally, Feb. 2014** > I am a principal of Dugally Oberfeld Inc General Contractors.
