I've worked with Denis on numerous occasions. He's honest, trustworthy, knowledgeable, and FAST! So far, I haven't come across a problem Denis has not been able to solve. Owning a business is not easy, and I've had many sub-contractors come and go over the years. Denis, I'll be keeping around! It's hard to find talent that is trustworthy and values your time enough to get things done, when expected.
