About the coaches

Sabina Strings and Navarro River String Camp

A lifelong passion for playing chamber music led to the formation in 2002 of the Redwood Youth String Camp, as a way of introducing young players to the joys of chamber music. At the request of their adult students wanting a string camp as well, Marion Crombie and Marcia Sloane started Navarro River String Camp in 2004 in the Mendocino area. Initially a small and local annual event, it very soon outgrew it’s locations and moved gradually southwards. The camp was very happily housed at the Angela Center in Santa Rosa until the tragic fires in 2017 destroyed those buildings, and it looked as if that might be the end of Navarro River String Camp. However, Marion Crombie and Cathy Allen were extremely fortunate to find an opening for summer 2018 at Santa Sabina Center in San Rafael, and now the spirit of Navarro River String Camp lives on as Sabina Strings.

Abigail Summers

Abigail grew up in the English countryside, playing piano and cello from an early age. She studied performance at the Royal College of Music in London and while there took an interest in Baroque cello and viola da gamba. Since moving to California in 1988 she has performed with various chamber and orchestral ensembles in Mendocino, Lake and Sonoma counties. A private cello and piano teacher for over 30 years, Abigail’s studio is now in Sebastopol, Sonoma County. She is currently principal cello in the Vintners Chamber Orchestra and cello coach for Santa Rosa Junior College and Sonoma State symphony orchestras.

Interest in Yoga began over 30 years ago due to a ‘nagging backache’. Abigail initially studied Iyengar style Yoga and completed a Teacher Training at Yoga Mendocino in 2005; since then she has taught Yoga classes in England and California and has helped many Navarro River string campers to ‘Stretch & Relax’.

The coaches playing together was really fabulous. Burke playing the cello suites was also a big plus. It just filled my soul and the piano trio at night was another soul-filling time. The entire five days was joyful and a great experience.
