Ms. Baumgartel is an active bow maker, constructing fine bows for professional musicians, conservatory students, collectors, avid adult players, select dealers and major violin shops in the United States, Canada, Europe and Asia.

Peg Joanne Baumgartel received her initial training in the Los Angeles workshop of Paul Siefried, with whom she worked from November 1986 through June 1993. The emphasis of her work there was on bow repair and restoration. After leaving the employ of Mr. Siefried, she established her own bow workshop in L.A. Remaining active as a bow maker and restorer, Ms. Baumgartel relocated her workshop to Washington state in 2000 to be with her husband, Morgan Andersen, an internationally renowned bow maker. Because the demand for her bows has continulally increased, requiring her full attention and commitment, as of 2013 Ms. Baumgartel is now concentrating exclusively on bow making.
