Rich came to St. Andrew in January, 1982. Back then, St. Andrew was a small country church, meeting in the converted carriage house on what was the Spreckels Sugar Family Estate. In 1989, things changed when the old building burned to the ground.

From the ashes, God raised up a new church building with a congregation that has been “on fire” and growing ever since. The one thing that has been constant for the past twenty-four years is change — change in Rich’s life and change in the life of the congregation. The verse that gives Rich hope and purpose is from Paul’s prayer for the Philippians: “…being confident of this, that He who began a good work in you, will carry it on to completion until the day of Christ Jesus.” (Philippians 1:6)

Rich graduated from Fuller Theological Seminary with a Master of Divinity degree in 1976, then went on to earn a Doctor of Ministry degree from San Francisco Theological Seminary in 1985. He grew up in Portland, Oregon, and met his wife Lorna at Portland Adventist Hospital, where she worked as a nurse and he worked as an orderly. They were married in 1972. Their daughter Julie and her husband Russ Findley have two children, Oliver and Cecily.  Since they live in Kensington, CA, Rich and Lorna get to see their precious grandchildren often.  Julie is an attorney with the Water & Power Law Group PC.  Russell is the Director of IT for Bebe, a women’s clothing company popular with the younger set.

Rich is passionate about bicycling (passionate is an understatement), builds custom furniture in his “Geppetto’s” woodshop, and is a neophyte fly fisherman.

brian_mayoMeet Brian Mayo

Brian is going through a 9-month internship at St. Andrew
as part of his journey through seminary school.

I grew up in Santa Rosa, and I went to the First Presbyterian Church there. I enjoyed very much going to that church–I attended Sunday School and Youth Group there.
I graduated from college in 1986, and in 1987-88 I lived and worked in south-west China. I taught English to college students there. I met my future wife there, and we got married in 1988.

We now live in San Rafael, and we have two children. We all attended St. Luke’s Presbyterian Church in San Rafael for 9 years. I taught Sunday School there, was an elder and I helped out with a variety of youth activities.

I am currently attending Fuller Theological Seminary in Menlo Park, studying to become a minister. I hope to graduate in 2 years. In addition, I have worked in Sonoma since 1995, since 1996 as a property manager.

I am looking forward to meeting and getting to know all of you.

dawne_carverDirector of Youth (6th – 12th Grade) and Adult Ministries  Dawne Carver
email: [email protected]

Dawne Carver became a member of St Andrew when she became baptized in 1995. She has been a part of choir and is very passionate about the drama ministry. She served in Children’s Ministry in the late 90’s.

Dawne became Director of Youth Ministry in 2006. After chaperoning on Caravan, a youth mission trip to Calais, Maine, she realized her calling to work with and live life with young adults. She feels that God had been preparing her for this role for a long time. There is a saying on a shirt that goes like this- “Chaos amuses me- I’m a youth leader!” Helping the youth embrace who they are in Christ can be messy and chaotic.

Dawne has worked in the restaurant world for over 20 years. She loves her job as a server. She gets to meet people from all over and enjoys learning and sharing stories. She loves food and wine, and enjoys guiding people in their dining experience.

Dawne is married to Paul Carver. They have 2 children, Rachael and James. In her downtime, she can be found dining out, wine tasting, reading, gardening, at a race track with her husband or walking, her first choice- on a beach.
