Wales F. Grow began his career with a co-operative firm called The New York Pianoforte Manufacturing Company and is listed as a partner in A. H. Gale & Company in 1842.  In 1847, W. F. Grow left the partnership with A. H. Gale to join William Christopher, establishing the firm of “Grow & Christopher”.

Grow & Christopher specialized in square grand pianos and built as many as 150 pianos annually. Instruments by Grow & Christopher were frequently exhibited at fairs and trade shows, and were generally awarded with high honors for design and construction. Grow & Christopher dissolved around 1857 – 1858, and there is no mention of either Wales F. Grow or William Christopher being active in the piano industry after about 1860.
