Marian and his team are the consummate hardwood flooring professionals and craftsmen.  The flooring job they did for us is beautiful and expertly done.  Not only that, Marian was able to give us a hardwood floor in one room that is above a concrete slab.  No one else gave us this option and we were led to believe that we were stuck with engineered wood that could be glued on the slab.  Not so…Marian gave us a gorgeous hardwood floor and it looks amazing.  His workers are very professional and work very hard.  Marian is very pleasant, easy-going and easy to deal with.  We will definitely use them again.
We would recommend Marian and his team for hardwood flooring jobs, with one slight caveat: we would encourage Marian to become more of an expert in the best environmentally friendly floor finishing options.  Even the standard (low VOC) stuff may be too much for people with chemical sensitivities.
All in all, they did a great job and we look forward to have them do our kitchen.
