"Monumental Mason" is the technical term for an individual who designs/makes monuments (for cemeteries, as well as other public locations). Some people prefer the term "Memorialist", however.
I should point out that the term "Tombstone" is not used in the industry, though. We call them markers, or monuments... occasionally you'll hear "gravestone" or "headstone".... but "tombstone" is not an industry term.
Within any monument company you may find an assortment of different professionals who specialize in various aspects of monumental masonry: letter cutters, stone cutters, stone carvers, etc.... In other words, any marker you see at your local cemetery may or may not have been worked on by more than one person specializing in one or more aspects of the Memorialist's craft.
Hope that helps!
