Our Team

Rev. Dr. Tony Osimo, Pastor, Head of Staff

Pastor Tony grew up on the coast of southern California, and the beach is still his happy place. Tony received his M.Div. from Union Theological Seminary in Richmond, Virginia (now Union Presbyterian Seminary), and earned his Doctor of Ministry degree from Fuller Theological Seminary. He and his wife, Anne, have two grown children; their son, Carey, and their daughter, Grace.

In his spare time, Tony loves skiing, traveling, scuba diving, reading, and especially cooking. His latest challenge is trying to master sourdough bread. Most of his free time is spent hanging out with his wife Anne, doing fun things like walking the ranch or along Moonstone Beach.

Tony served as the chair of the Pastoral Ministry Nominating Committee (PMOT) for the Southern California Presbytery and was part of the organizing team of that Presbytery. Before coming to Cambria, Pastor Tony served churches in Boca Raton, Florida; San Clemente, California; and Monrovia, California.

Interesting fact: Tony can no longer eat or drink anything with caffeine. Carey and Grace trust him with their chocolate, which is never safe with their mother.

Small Wonders Preschool Leadership Team

Director: Shirlin Ellis

Shirl became the preschool director at Small Wonders after having been a teacher at the school for over 11-years. She has a strong passion for nurturing child development.

Shirl is originally from the Caribbean islands of Trinidad & Tobago. She moved to Cambria in 2001 after meeting her husband, Robb. Together they have two beautiful daughters Brooke, & Brianna. They also have three Hungarian Vizslas that are also the equivalent to their children. All three dogs share a J name, a tradition that was started by her husband.

In her free time, Shirl loves to hang out with her family, whether it is taking the dogs to the beach, fishing, cooking; which she’s really good at, or just hanging out around the house!

Dianne Greenstein, Director of Finance & Communications

Dianne is originally from New York, and spent her formative years in Los Angeles. She is a graduate of UCLA, and has an extensive background in finance. Among Dianne’s previous positions, she has worked for Michael Jackson’s Neverland estate, as well as the Sabon Entertainment Group. Most recently she was in property management in Palm Desert.

Dianne loves most any pastry with blueberries in it.

Assistant Director: Erika Treller

Erika has been a preschool teacher for over sixteen years, and also has her director licensing qualifications. Before teaching at Small Wonders, Erika taught at an outdoor nature preschool, a college child development center, and trained puppies as a professional dog training instructor.

When she's not working with little ones, you can often find her watching old movies with her husband and cat, gobbling dark chocolate, or making sun tea in the garden with her crew of angel statuary.

Her grandparents were CPCC church members for many years, so Small Wonders holds an extra-special place in her heart. She feels blessed to help Cambria's littlest learners embark on their educational adventures in discovery, creativity, and faith.
