Heidi is currently a freelance violinist serving the musical needs of San Diego county. She has been playing for decades, starting with the Suzuki method under Shirley Stafford and learning to play by ear before learning musical notation. Many years later (she started violin when she was 5!) she enrolled at the Biola Conservatory of Music where she studied under Dr. Kangwon Kim and had the opportunity to study abroad under the tutelage of Heidelberg Symphony concertmaster Thiery Stoeckel.

Robert Rotzler has been playing, recording, and teaching the violin, viola and mandolin in the Southern Californa area for 40 years. His many credits include the San Diego Youth Symphony (Associate Concertmaster), Chapman College Chamber and Symphony Orchestras (Concertmaster), Orange County Community Orchestra (Co-Concertmaster) and San Diego State Symphony. He is currently the violinist and mandolinist of the nationally award-winning world beat group, the Middle Earth Ensemble.

Adriana has played in many orchestras/ensables over the past two decades of her cello playing tenure. She does not make the cello her profession, but does play in many groups at an elite level. She has taught numerous students contrary to not making it her primary source of income. When not playing her cello she is teaching the youth of tomorrow at a local elementary school where she is a devoted grade school teacher. She is currently involved with the Grossmont Symphony and satellite groups outside of the University Avenue String Quartet.

Josh plays the viola and updates this site. Like Adriana his early musical influence stemmed from the school system in El Centro; after which he took his experience from the Valley to San Diego where he enjoyed playing in many groups at UCSD and the area. He has played in many orchestras including the IVSO, PCSO, and many ensamble groups. Currenly he is playing in a string quartet with his siblings outside of the University Avenue String Quartet.

Aside from playing the viola, Josh makes his career supporting continued education at UCSD Extended Services and Public Programming where he fulfills computer and networking support needs. He also is the main contact point for this site and related media operations.
