Casie Schornick

Casie Schornick Vocals

With so much musical talent in her family, Casie was certain to get the music bug! She began singing at a very young age, and really started to develop under Jim Wells and the Jazz@8 high school program. Like many other Chains Required members, she spent time singing with the Columbia College Big band, sharing the stage with many greats like Bobby McFerrin and Cornelius Bumpus. She continued as a Voice and Music Education major at Sacramento State University and later performed at jazz festivals throughout the USA. Before joining Chains Required, Casie was a member of the Lil Diamonds.


Christy Nava Vocals

Christy’s love for singing was cultivated at a wee age, by her Dad, who taught her to sing lead and harmony vocals. Performing in Musical Theatre and A Capella Choir cemented her desire to be on stage. Some of her projects include singing for Christy Hollywood and the Walk of Fames (Rockabilly), The Barn Dogs (Americana) and she’s currently working on writing an album of her own original songs. Christy has a wide range of stylistic and vocal influences. She looks to Billie Holiday, Etta James, Janis Joplin, Alison Krauss and Gwen Stefani for inspiration, just to name a few.

Steve - Guitar

Steve Bernd Guitar

Steve took up guitar during high school, and quickly realized he had a special bond with the instrument. He has played a wide variety of music including pop, rock, blues, jazz, and R&B in bands that opened for such artists as Emmy Lou Harris, Hank Williams Jr., and Diamond Rio. His composition "Steve's Quick Pick" was featured on MTV's "Date My Mom Show" and he appeared as an up-and-coming artist in Guitar Player Magazine's New Talent section. Steve studied under former GIT instructor Rick Severson and loves playing his vintage Fender Stratocaster.


Kevin Kaiser Drums

A native of the Bay Area, Kevin is no stranger to Tuolumne County.  He attended Sonora High School and Columbia College where he played drums with the Columbia College Jazz Band in the mid-1980's.  Before joining Chains Required in late 2015, Kevin played in various country, blues, rock and jazz bands throughout the Sierra foothills and the Bay Area.  Kevin currently works and resides in Alameda County and spends much of his time in the Sonora area playing music and hanging out with family and friends.


Gary Goldsworthy Keyboards and Vocals

Gary considers himself an organ player who happens to also play piano. Both are understatements, as he adds a powerful keyboard foundation to the band. Of course, organ is paramount to Chain Required’s sound and Gary delivers. But his piano and other keyboard contributions are also significant, bolstered by lead and background vocals. Gary has toured extensively, and is currently finishing up his second album. He was previously with Wayne Baker Brooks, James Armstrong, and the Chicago Blues Festival Europe Revue.


Dan Parks Bass

Dan has played bass for nearly forty years, starting in early high school. His first few bands were truly terrible, but as time went on he met better musicians who helped bring up his skills. He played in Bay Area clubs throughout college, and shocked his parents upon graduation by going on the road with a disco band. With that experience out of the way, he decided music would become his hobby rather than vocation. More recently, he has been part of the house band at Sierra Repertory Theatre and a regular member of the Columbia College Big Band.


Ryan Rainville Sound Engineer

A graduate of Audio Technology at Modesto Sound Institute, Ryan has a diverse and eclectic background. He previously toured with metal act Fuggermuddas, and followed up with a stint as sound engineer for neo folk hipsters The Strum Ponies. In his spare time, Ryan writes dyslexic poetry.
