History of
W.J. Grosvenor

W.J. Grosvenor & Co., Inc. has a long history of service to the construction and finishing trades in New England. Founded in 1910 by Walter J. Grosvenor as a builder of sidewalks and railroads, Grosvenor has evolved and changed along with the times. Bernard S. McHugh, the father of Chairman Emeritus Joseph R. McHugh and the grandfather of current President and CEO Bernard J. McHugh, began working at W.J. Grosvenor & Co., Inc. in 1912. When Mr. Grosvenor passed away in 1930, Mr. McHugh purchased the company and it has been a family run business ever since.

Sales Staff

Mark Parets
Director of Sales 781-704-5271

Mark Parets, with more than three decades of experience in the floor covering installation industry, began his career at his family’s sales agency, Raznick-Faulkner, Inc. (RF).

While at RF, Mark focused on growing the sales agency’s residential and commercial flooring installation business by servicing floor covering supply distributors across the USA and Canada. In 1998, Mark took the helm at RF and relocated from California to Massachusetts, where he raised two accomplished sons.

In addition to his work with RF (now dissolved), Mark has spent the past decade expanding the market footprint for a local Boston-based surface preparation manufacturer. He did this by increasing both sales and market share exponentially. A fixture in the floor covering installation industry, Mark has also worked as a sales executive and manager for three different manufacturers of adhesives, powders, tile products, tools, and sundry installation products.

Mark’s vast career has provided him with a deep understanding of all facets of residential and commercial installation products and applications. He is proud to bring his vast knowledge of the entire sales and distribution process to WJ Grosvenor, where he will continue to build relationships in an industry he loves.

Scott Esmay
Technical Support Manager

Scott was born and raised in the San Francisco Bay area and has worked in the flooring business for over 30 years. He is second generation in the industry as his dad was also a flooring contractor who opened that door for him! Over the years Scott has installed many types of flooring. He is a certified Forbo Master Installer as well as an Advanced Armstrong, Toli, Mannington, Loseal, and Altro Installer.

After many years on his knees, he was ready for a change. In 2012 Uzin approached Scott with an opportunity to work as their Senior Technical and Training Manager for North America to include Wolff tools. His responsibilities included training customers and employee’s on Uzin and Wolff products. He has traveled all over the world with Uzin until Schönox offered a similar position with less air travel and more time to spend with family and friends. He was hired by Schönox as the Technical Support Manager covering the Mid-Atlantic and the New England Markets.

He is very excited to join the W.J. Grosvenor’s team and look forward to working with all of you! Scott can be reached at 978-735-3365 or at:
