Read what our customers say about us.

Wonderful family owned business - Janet was amazing! So helpful with the overwhelming task of choosing granite countertop material & then finding the exact slabs we loved! Steve so helpful with measurements & directing the prep work for install. Minimized seams & reworked layout to accommodate exact layout we wanted. Fabricators definitely paid attention to details - Quartzite material super hard & they took their time to get it right - even with us waiting impatiently for the install date. Workmanship on finished countertops was impeccable! We could not be happier with our countertops & our experience with the entire team at American Marble.  -Jim W. (Yelp Review)

Over many years our family has bought several finished marble and granite pieces from American Marble and Onyx.   Every piece has been carefully cut and finished.  We have been extremely happy with the results each and every time.  They are a quality company from start to finish.  This is a family business and you can tell by the way they really care about their customers.  The last piece we ordered was a ten foot piece of marble to go on our new bay window.  It turned out spectacular!  When it was installed the attention to detail was amazing!  If I could give this company 10 stars I would!!  I would not hesitate to recommend them. - Linda M.

I just finished a custom bathroom in my house.  The marble counter top was the last item installed.  The finishing work in any project is in the details, and American Marble made sure that the details were perfect.  Janet, and the entire staff, were a pleasure to work with.  They went out of their way to help me pick the perfect stone for this unusual bathroom.  It was cut to perfection to fit a custom cabinet we had made.  Their attention to detail; their advice in picking the stone, and the fact that they came in on time and on budget are some of the reasons they deserve the highest praise.  They have my highest recommendation. -Bob G (Yelp Review)
