Sharon Hansen


Email Sharon

My husband, Jim, and I have been married since 1981. We were self-employed for 29 years and owned a home-building business, gutter business and vacation home. We have three daughters, three amazing sons-in-law and currently have five grandchildren and one on the way! Because of God’s grace, all of our daughters were home-schooled or attended Christian school. 

Currently, Jim and I both work full time – Jim is a superintendent with Scull Construction and I am an Administrative Assistant at OBC. We both volunteer in various roles at OBC. Our church family is of vital importance to us and we believe, as Disciples of Christ, that we are called to fulfill our role in His church and to be loyal, serve and forgive. I’ve loved my role in the OBC office for the last six years and see every opportunity as a chance to serve Jesus!
