Sean Jacobs
Confirmation Coordinator and High School Youth Minister
Sean grew up in Foxboro MA. Here, he spent his time between his faith formation at St. Mary’s Foxboro and earning his Eagle Scout down the street. Now, he lives with his wife Daniela in Mansfield MA, where they enjoy exploring local hiking trails and cooking together. Professionally, Sean has spent the last several years working in Catholic education as a volunteer, paraprofessional, and High School theology teacher. Sean first studied philosophy and religious studies at Emmanuel College, then earned graduate degrees in both theological studies and education at Boston University. Now, he is excited to take on new roles and responsibilities here at Saint Mary’s Parish Holliston. Combining his love for theology and education, Sean hopes to help students grow both intellectual and spiritually, teaching to the whole person. Taking to heart the message of Saint Anselm, Sean’s teaching seeks to embody the spirit of “faith seeking understanding.”

Abigail Kelley – Lanser
Director of Music
Abbey grew up in the next-door town of Hopkinton, MA. She traveled halfway across the country to Northfield MN to earn a Bachelor of Music in Organ Performance with an Emphasis in Church Music from St. Olaf College. There she gained leadership experience both in the choral setting and at the organ bench. Now back home in Hopkinton as a St. Olaf “Ole” alum, Abbey is excited to share her love of musical worship with St. Mary’s. Outside of music and composition, her passions include poetry writing, language learning, and philosophical-theological discourse. Most of all, Abbey hopes to give joy and bold encouragement through her musical ministry.

Mary Beth Harris
Parish Secretary
A native of Holliston, Mary Beth had her first job as a teenager right downtown at Fiske’s. She has been St. Mary’s Parish Secretary for over twenty-five years. Her oldest son Christopher, and two lovely daughters, Hannah and Mary Kate received all their sacraments at St.Mary’s and visit the parish regularly. Mary Beth enjoys welcoming new families to St. Mary’s, and values the many friendships she has made over her years at the parish. While she has seen many changes during that time, the spirit of St. Mary’s has remained constant – a spirit of faith, friendship, family, generosity and love. Her favorite quote comes from St. Mary’s very own Sr. Ricci: “Jesus, I love you and I trust you!”

Jennifer Burgett

Jennifer spent her early years in Northeast Ohio, moving to Massachusetts during high school. She attended Framingham State University, graduating with a Bachelor’s degree in Economics and Business. She continued on to earn her Master’s degree in Business Administration from Bentley University. Jennifer worked for a number of years for Standard & Pools DRI, then Global Insight in Sales Operations. Over the past several years, she has been involved in volunteer work for various organizations, including the Holliston Schools, Girl Scouts, Boy Scouts, and St. Mary’s. She is looking forward to combining her business knowledge with her love of service, to support the parishioners of St. Mary’s. Jennifer resides in Holliston with her husband Rodman, their three teenage children, and one Cavapoo. “For I know the plans I have for you; to give you a future and a hope.” Jeremiah 29:11

Mary Sanning
Business Manager
Mary is a resident of Westborough, MA, where she lives with her husband, Bob Thompson. She has worked in corporate finance for 25+ years, and in 2016 felt the call to bring her finance skills to a Church environment. With an undergraduate degree from SUNY Cortland, and an MBA from Babson College, Mary has worked for Data General, PeopleCube and most recently Asure Software. Several years ago, Mary had the opportunity to pursue a Masters in Pastoral Ministry at Boston College which she completed in 2005 and led her to work for 3 years in Religious Education and RCIA at St. Luke’s Parish in Westborough. Missing the finance element in her job, and with an invitation from former colleagues to join PeopleCube, Mary returned to the corporate finance field for 11 years. Mary grew up in Shrewsbury, currently resides in Westborough and is active in church ministry at Holy Family Parish in Worcester. For Mary, there was always a pull to find a way to combine her talents in finance with her love of the Church, and she is pleased to have found the right combination at St. Mary’s.
