Throughout his pre-college training Daniel Altshuler studied drawing, painting and wood carving of lettered signs. He studied with special instructors in painting, still life, and life drawing classes through the Art Institute of Boston and Boston University. When at the Museum School, he developed his skills in life studies and human anatomy. Through the various fine art studies in drawing, designing, clay modeling, stone and wood carving, welding and metal work, casting in plaster and metal, painting, printmaking and photography, the Museum School prepared Altshuler for his future training with Walker Hancock, Sculptor. After meeting Hancock, prolific in monumental figurative sculpture, portraiture, numismatic work, and bas-relief, Altshuler worked as sole assistant to Hancock for the duration of thirteen years. Altshuler‘s sculptural training with Hancock ranged from small works to monumental size works. While developing Hancocks work from statuary to busts in clay, plaster, bronze and marble, Altshuler worked concurrently on his own professional commissions in an adjoining studio. The immediacy of Hancocks‘presence and his emphasis on bas-relief with the figure, portraiture and lettering, in the classical way, developed Altshulers skills and knowledge to become the professional sculptor he is today.

While fulfilling the demands of his private clientele and own independent works, as a curator Altshuler chaired two massive exhibitions on Cape Ann, Massachusetts in 1997 and 1998. The first, "Sculptors of Cape Ann, From Medals to Monuments", an artistically rich community was given the opportunity to discover and honor the sometimes overlooked, yet significant sculptural roots of this seaport town north of Boston. As a member of the Board of Governors of the Rockport Art Association, Altshuler created, curated and chaired this landmark event honoring 19th and 20th century sculptors who worked and lived within the Cape Ann area. Some 300 numismatic, monumental, statuettes, bas-relief and portrait busts were assembled. Following this successful venture came the nationally recognized exhibition entitled, "Americas Sculptural Heritage, Anchored in Gloucester," executed for Mayor Bruce Tobey to commemorate the Citys 375th Anniversary.

Currently, Altshulers numismatic commemorative works include Henry David Thoreau, Paul Revere and Louisa May Alcott. His recently unveiled portrait bust of Louisa May Alcott may be viewed at Orchard House in Concord, Massachusetts.
