An industry leader for over thirty five years, I have played many roles throughout my career from master carpenter to General Contractor and Construction Manager, as well as Design-Builder. I have created many successful projects that were given recognition in the community, and by the Owner's, and have enhanced the built environment throughout the country.

I have also worked in the very large corporate sector as a Director of Preconstruction and Estimating where I was fortunate to have the opportunity to create, in collaboration with the Owner's, Architects and Engineers, and all other project stakeholders, some of the most beautiful and efficient buildings being produced. It was in this environment that I also was able to create LEED Certified buildings, to add more in the market sectors that I was working in. These market sectors included, but were not limited to, hospitality and resorts, judicial, general office, retail, higher education, corporate office, and many other building types.

I obtained my LEED AP credential in an effort to be able to be even more relevant in the design process and create even more efficient buildings and creating a better working and living environment for wherever, and for whomever, I was involved in producing, with all of the team members, these special buildings that are now standing and functioning as positive daily reminders of what can be accomplished in this industry utilizing knowledge and tools available to us.

    I'm impressed, I have to admit. Seldom do I come
    across a blog that's equally educative and entertaining, and without a
    doubt, you've hit the nail on the head. The issue is something not enough folks are
    speaking intelligently about. I am very happy that I stumbled across this in my hunt for something concerning this.
