Thanks for making our days smoother and more productive

Great to see your beautiful spread in Builder + Architect. You live it every day more than anyone I know, and you’ve honestly won the lion’s share of our business from the ground up. Our field staff are calling your yard first more and more often because call by call and load by load you are getting us what we need faster, more cheerfully, and at a better price, and often when others can’t get it at all. Thanks for making our days smoother and more productive! Thanks also for being such an extremely loyal partner for the island. We at SMCo and at the MVBA are so grateful.

Narcisa is probably the finest sales rep I have ever had in my 40 years of practice

She is responsive, intelligent, very well informed about the product she represents and humble enough to do additional research if necessary when she is not sure. Her responses are immediate.  She fights for the architectural causes that are important to our design philosophy and we feel she puts us first at all times. There could not be a better relationship. She is an asset to your company and receives the highest praise from this office. We do not hand out these stellar compliments freely. You should feel grateful & privileged to have her as a most significant part of your team. We certainly are!  5 STARS!!!
