He is a timely, honest, reliable, hardworking, a skilled carpenter, and so reasonably priced . He keeps the workplace clean and neat.



I appreciate the fact that you kept me abreast of progress and got the job done pretty much right on schedule in spite of rain, bats, bees, wasps, rotten wood, and ticks.

Our renovation project was exciting,with many difficulties we had to struggle to overcome. You are given the majority of credit for the projects great success. We love the results. Thank you for all your help in making our project a totally pleasant experience. You made us feel like we had an architect, general contractor and carpenter in our family plus made us feel like part of the team. You were able to combine our ideas with your thoughts, knowledge and skills to come out with a result that was better than anyone could imagine. And we had fun throughout the project on top of everything.

The kitchen design and workmanship is outstanding including the cabinetry, counters, back splash and custom items. The flooring throughout is magnificent including the tile work in the bathroom.
The crown molding throughout and bead board in the bathroom add a touch of elegance. The work in the bed room rearranging duct work and creating a new closet makes the room more open.

Your ability to perform the entire project including the coordination of plumbers and electricians to get the job done ahead of schedule and under budget is amazing. We are very pleased with your skills and the entire experience working with you. I am not sure everyone would want to be as involved as we were, but I am confident that with you the result is always at the highest level of quality for a very reasonable cost.
