Our Team

Tom McNall is an authority on terrazzo, tile and marble, and has a passion for stone and marble equaled only by his wealth of expertise and education in the field. He was taught personally by 3rd and 4th generation "Stone Men" from the "Old Country" in Italy. Tom offers the benefit of years of expertise and experience, directly, and through his team of highly trained employees. His long working relationships with product manufacturers, fabricators, trouble shooters, educators, editors, association directors and sellers of stone worldwide have both fed his passion for stone and marble and made him Canada�s foremost expert in the stone industry and now in all of North America.

For almost 6 years you could've heard Tom on the radio every 4th Saturday on "The Home Show With Mike Stubbs" on News Talk 1290 CJBK out of London ON. Tom currently writes articles for trade magazines such as Stone Business. Recently, he was elected to serve on the MIA Board of Directors. He does not consider what he does work because he enjoys doing it so much.

Greg was a graduate of UWO where he achieved a Bachelors Degree in Economics and went on to a career in banking and purchasing for over 13 years. He entered into the stone business with Tom in 2004 and has helped GNS gain valuable corporate and commercial contacts and contracts. Greg has worked with our crews and knows the amount of work involved in doing the job right the first time. Today he spends his time setting up jobs, training sales staff and keeping Tom out of trouble.

Greg is a well respected family man and a leader in the local business community. GNS couldn't be who we are today without Greg!

Contrary to popular belief, Jane is not Tom's wife. Nor is she the movie star of the same name. But who else could keep him organized and ensure that he keeps his appointments? Jane is the chief bean counter and personal assistant to Tom. She is what keeps the GNS machine well oiled.

Sherry McDonald comes from a long family line of construction and followed in her father's foot steps. Sherry's father owned a construction and manufacturing company for over 40 years. Sherry eventually moved into tile installation and progressed into the stone restoration industry. Sherry always stays up to date on the latest technology in the stone restoration industry. The team in Chicago brings many years of experience and has been working with Tom McNall for over 8 years now.

Sherry's love of the stone restoration business is to make old, poorly installed and chemically abused stone come to life again as the day it was installed. To her, every job is a form of her personal art.

Sherry has lived in the Chicago area her whole life and stays busy raising her three children with her loving husband. Sherry also is an artist in her free time.

Ashley comes from the business management field and over the past 10 years has continually added splashes of color along her way with her background in interior design. After marrying Dimitrios, she got involved into the marble and granite business, diving in to assist with fabrication in the shop or pick out colors with clients in the showroom. Her continual drive towards educating herself (and others) regarding everything there is to know about the facts as well as the fluff.

She looks forward to concentrating on the restoration of landmark properties and historical buildings, giving them a new life.

Aside from being married to her best friend, she is the mother of four beautiful and intelligent children and one loyal and loving dog.

Dimitrios was born in Greece and as long as he remembers has always had a passion for natural stone. His family owned quarries of marble and he is very familiar with the material. Many unique types of marble are from his home town, such as Thassos (Snow White), and he strongly believes that natural stone is a conduit for a balanced lifestyle.

He first graduated from the Greek Merchant Marine Academy as a marine engineer and has traveled throughout many countries. Later he expanded into entrepreneurship thoroughly including a wide variety of industries ranging from Information Technology in Robot Engineering to bar owner of several establishments and later to natural stone fabrication. As a natural salesman, he has an excitement for bringing unique products and services to the table, thus realizing that his passion for natural stone grows everyday more and more and he is committed to educating the public the right way of maintaining the stones to their original shine, organically.
