Pronouns: she/her

Sara loves working as a collaborative team with the outstanding staff at WBUUC! Working here allows her to express her creativity, love of humans, and dedication to spiritual development for people of all ages. Having grown up UU in San Diego with her husband Shawn, Sara finds living in the midwest is a magical and challenging experience of learning to love the seasons, and learning new lingo; for example “Grey Duck” and “Hot Dish”. Now with two midwestern native children, Jamie and Emily, the Goodmans are here to stay.

Sara says,

We are dedicated to living our values, both in our actions as a church, and in our individual lives. It is a pleasure to serve people who are so deeply determined to grow their souls and serve the world in love.”


jack-gaede-bio-photo-150x150Rev. Jack Gaede, Assistant Minister / (651) 204-8204
Pronouns: he/him

In his fourth year with us, Jack feels well-suited to his ministry portfolios: Welcome, Membership, Coming of Age, and Belonging & Community. Born and raised in northern Minnesota, Jack has spent his entire adult life in the Twin Cities. He lives in north Minneapolis and keeps busy with his friends and chosen family. Pastimes include puzzles, pickleball, reading, and seasonal exercise. Don’t get him started about all the winter activities he enjoys!

Jack says,

As I embark on my fourth year at this church, I am excited to help support the church community through the multiple transitions they are in. It’s kind of like a portage between two lakes, and fortunately, I love portaging.”

Pronouns: she/her

Amy Peterson Derrick comes to us from serving as Professional Lifespan Religious Educator for 10 years at the Unitarian Universalist congregation of Flint, Michigan.

Amy says,

I find our UU faith when engaged in advocacy work, walking (or running!) in nature, gardening and in spending time with my husband, Mark, and our two amazing, budding UUs: Alexandra and Lennon. I can’t wait to make new discoveries and to grow and serve alongside all of you at WBUUC.”


nico-van-ostrand-bio-photoNico Van Ostrand, Assistant Director of Religious Education / (651) 204-8307
Pronouns: name only & they/them

Nico’s UUism and approach to Religious Education are deeply rooted in their Social Justice and Women’s Studies background. Nico learned what it means to be UU from this WBUUC community, and is grateful to help guide the next generation now. They are currently finding exciting ways to deepen their UUism as a seminarian at United Theological Seminary. Nico’s favorite spiritual practice is tai chi, particularly the Fan Form. They spend more time than is reasonable encouraging their two cats, Max and Louie, to stay off their computer keyboard.

Nico says,

I value belonging to a community where I can explore and fully live my deeply complex identities, and know that my journey will be supported and celebrated. I strive to do my part in making the Religious Education program a place where UU kids can feel that same sense of love.”

Pronouns: she/her

Olivia grew up in Iowa and began playing the cello at the age of 4. She attended Luther College, where she studied music performance and religion. It was at Luther that Olivia met Karla, and began The OK Factor in 2012.

Olivia currently enjoys several job titles; Cellist and co-founder of The OK Factor, SEO Specialist at ArcStone, Inc., and most recently, co-interim music director at WBUUC. She is thrilled to join the WBUUC community in this way.

Olivia lives in southeast Minneapolis near Lake Nokomis, with her husband, Jonny, and their son, Charlie.

Olivia says,

Within our 10 years of performing and writing together, Karla and I have not only remained best friends, but have learned to divide and conquer; sharing workloads, responsibilities, and learning each others’ strengths. It is this relationship, paired with our musical passion, upbringing in the church/sacred music, and infinite wisdom from Carol, that we hope equips us to learn and grow alongside the WBUUC congregation in this time of transition and change.”

Though born in Wisconsin and raised in Georgia, Karla claims the midwest as her home after attending Luther College (2013) and residing in the Minneapolis area for six years. Her formal training is in violin performance from Luther where she met cellist Olivia Diercks and began their crossover duo The OK Factor in 2012. The two have enjoyed nearly a decade of shared performing and deep friendship, alongside witnessing the growth of each other’s families, careers, and personal lives.

You can find Karla close to her computer designing brands for creative entrepreneurs, working as the Brand Manager for hope*writers, and most recently co-crafting the musical life of WBUUC alongside co-interim music director and duo partner, Olivia.

Karla lives in Hopkins with her husband, Gavin, and their golden retriever, Lucy.

Karla says,

It is a true honor to join the WBUUC team and share in the rich musical tradition that lives in the hearts and spaces of this community. I am so excited to work with my dear friend and partner in musical crime, Olivia, as we do our best to fill the big shoes left by Carol and ride the wave of change alongside this beautiful congregation.”

Pronouns: she/her

Erin found WBUUC via a Google search in 2010 and like many, had a transformative experience sitting in the sanctuary on that first Sunday she attended. Quickly, she became a member and went “all-in”. In addition, Erin contracted with WBUUC for many years to maintain the church’s website and other projects. Bringing a diverse design background in print, web, video and multimedia, she’s pleased to now be part of the staff – and continues to manage the website, assist with church communications and technically support the multi-platform worship services. Erin moves through this world graphically, loves to find the sacred in the simple and feels very much at home.

She says,

I’m continually inspired by this space, the congregation and the collective spirit among us. So grateful to have the opportunity to serve you all in this capacity.”
