Andy began square dancing as a member of El Camino Reelers 3rd square dance class in the Fall of 1986, and attended his first IAGSDC convention Explode The Rose in 1987. Shortly thereafter, he was invited to join the Gold Rush performance team based in San Francisco. He danced for many years with El Camino Reelers, Foggy City Dancers, Midnight Squares, Stanford Quads, and Top Cats.
By 1989, Andy had tried calling some singing calls for Gold Rush and at club record nights for El Camino Reelers and Foggy City Dancers. Andy attended the first GCA Caller School in New York in 1989, and called his first convention "tip" at Peel The Apple in New York. Andy was also one of several callers for the Foggy City Performance Team using complex, well-rehearsed choreography by Steve Browning.
In 1991, Andy became club caller for El Camino Reelers in Palo Alto, CA., and taught Basic, Mainstream, and Plus classes for them until he moved away in 2004. In 1992, Andy started teaching Basic and Mainstream for Foggy City Dancers in San Francisco, again serving in that role until 2004. Andy also taught Advanced and C1 classes for El Camino Reelers and Midnight Squares. In 2004, Andy moved to South Florida where he taught beginners classes for the South Florida Mustangs for a couple of years.
In 2005, Andy discovered the joys of contra dancing and attended his first LGBTQ* "gender-role free" contra dancing camp in May. In August 2007 Andy attended a contra callers' school and by Fall 2007, Andy was calling contras too.
Andy has been on the calling staff of six IAGSDC conventions: Diamonds In The Desert Albuquerque 1992, Stars, Thars & Cable Cars SF 1996, Anchors Aweigh With a Half-Sashay San Diego 2003, Remake The Heatwave Phoenix 2004, Star Thru The Silicon Galaxy Santa Clara 2005, and Gone With The Windmill Atlanta 2011. Andy is also a caller coach and has been on the staff of GCA Caller Schools, the Rhythm Records Caller School, the Northeast Caller School, and the Alguire Memorial Callers School.
Andy is a member of CALLERLAB and is a past president of the Gay Callers Association. Andy serves on the board of Lavender Country and Folk Dancers (LCFD), which joined the IAGSDC as an affiliate member in 2010.
Andy volunteered to become the Golden Boot Award "stepmother" when Freeman Stamper gave up that role - which entails providing the badge "dangles" for new award recipients, and maintaining an archive of Golden Boot history and information.
