Su-San Yio started piano lessons at the age of four in Singapore where she grew up, and promptly fell out of love with it because she preferred to climb trees and ride her bike. However, her mother wisely understood that a four-year-old would not be capable of taking the long view and thus did not cave in to tantrums about quitting. Several years, lots of tears and various teachers later, Su-San began to enjoy music under the firm but loving guidance of Anne E. O’Hara. At the same time, Su-San’s love for ballet led her to form a deeper connection to music through dance and ballet music. Through her involvement in student theatre, she also observed how music enhanced dramatic performances. Su-San is now deeply grateful to her mother’s vision and steely resolve that her daughter would have a music education. 

Su-San was awarded a Government of Singapore scholarship for undergraduate and postgraduate study in the United Kingdom, where she was awarded a BA in Philosophy, Politics and Economics from the University of Oxford, and a MSc in Development Studies from the London School of Economics. In college, Su-San was a founding member of the Oxford PPE Society, joined her college boating team, and dabbled in dance and theatre. Upon graduation, Su-San worked in the Singapore Government for several years where her portfolios included bilateral and multilateral trade relations and negotiations, competition and consumer affairs, labor policy and tourism initiatives.

In 2012, Su-San moved to the US with her husband and three sons, where, instead of spending her days negotiating with trading partners, business, consumer or labor groups, she now negotiates with the boys about how much snacking is appropriate between meals, or whether shorts are appropriate dress for 50 degree weather. Her sons take piano and violin lessons at CCSM and she appreciates that they are enjoying their musical pursuits tremendously. She has resumed piano lessons so that she can adequately accompany her boys in performances, and wishes she had practiced more as a child. 

Because she forgets a day only has 24 hours, Su-San has volunteered at school and at church, and at AYSO as an assistant soccer coach despite not knowing how to pass a ball. She is also a member of the organizing committee of the John Child Walker Music Competition. Her husband, Cheng Hang Teo, is always available to make sure the kids are delivered to performances and soccer games on time, and is an ever-ready, never-ending source of encouragement and support.

Danielle was exposed to music at a young age through CCSM.  She started in the Music for Young Children class at age 2, moved on to recorder, and finally private flute lessons through age 20.  While she did not make a career out of music she attributes many of her life successes to her musical background, as that is the forum that gave her much confidence and where she developed many leadership skills.  Danielle earned a bachelor's degree in accounting from Cal Poly Pomona, earned her CPA license, and spent the first fourteen years of her career at a local public accounting firm in Glendora.  She is now the CFO at Foothill Country Day School in Claremont and plays with the school’s orchestra whenever she has a chance.  She is very passionate about CCSM and bringing music into the lives of young children.  Danielle and her husband live in Upland with their two children, Devon and Ashlyn.
