Under Dr. Lea’s leadership the church experienced such exponential growth that we outgrew the Suisun Campus as our sole location. Consequently, Dr. Lea led us to a 48,000 sq. ft. building which would become our new campus. The Fairfield Campus, located at 1735 Enterprise Drive, Building 3, in Fairfield, California, was a $4.5 million purchase in addition to a $1.5 million renovation project, which includes a 900+ seat sanctuary, a 200+ seat fellowship hall, a state-of-the-art nursery, a conference room, a high-tech audio/visual room, numerous multi-purpose rooms, administrative offices and a 300+ spaced parking lot. On Mother’s Day Sunday, May 9, 2004, the church moved from 601 Whispering Bay Lane to its new Fairfield Campus site. Dr. Lea proclaimed:  We are the church of the “Joshua Generation.”

In December, Mount Calvary re-opened the Suisun Campus with a noon Bible study, and on Sunday, January 1, 2005, worship services resumed.  We are now one church in two locations and a multi-ethnic ministry that includes a Spanish ministry and sign language.

Along with our new sanctuary, an additional administrative wing was completed providing more office space, a larger library and classrooms for Christian Education materialized in 2006. This new wing is equipped with a state-of-the-art computer lab.  On Saturday, June 24, Mount Calvary opened the Didasko Christian Bookstore.  In Greek, Didasko means “to teach, to educate, to train and to learn.”  Our bookstore is a licensed retail business stocked with various Christian-related materials and setup to place special orders for merchandise not available in the store.

• Didasko Bookstore embodies our mission statement: “To lead individuals into a dynamic relationship with Jesus Christ and equip them for service to God and humanity.” Our store manager is Sis. Adrienne Edington.
• In June, 2007, Dr. Jerome King, a son of Mount Calvary became our Executive Pastor.  As Executive Pastor, his role was to focus on the staff and work with the administration in the day-to-day affairs of the church. His expertise as a theological educator, administrative practitioner, consultant and speaker greatly enhanced the church body.  His extensive studies in leadership coupled with his vast experience, aided in mobilizing volunteers to engage in service. Dr. King helped Dr. Lea to lead Mount Calvary in establishing its current mission statement, core values, visions and goals.
• In April, 2009, the Mount Calvary “Twelve Tribes Family Ministry Care Plan” was developed to accomplish the goal of “core ministry teams.” Partnering with the Pastor, the ministry teams’ responsibilities are to minister to the physical, spiritual and emotional needs of each member. To accomplish this endeavor, teams were selected to become “tribe leaders” of members who are divided alphabetically by their last names.
• Rev. David L. Reaves became the first full-time Youth & Colligate Pastor at Mount Calvary on July 4, 2010. Worship for this age group is held in The Zoe Center, Youth Sanctuary. Our vision for this facility included a deli and coffee shop, Christian school, gymnasium, larger bookstore and much more. 
• On October 22, 2011, our Wi-Fi deli and coffee shop, He Brews It! Cafe, held its grand opening. It is open to the public six days a week. It is a top-notched, full-fledged café with delectable delicacies and an available room that can be reserved for meetings.
• We see a day when we will purchase the 94,000 square feet facility just across the parking lot from the Fairfield Campus location. Meanwhile, the church membership continues to grow spiritually and numerically. More than 4,500 people have been added to the membership.  In 2005, “Outreach Magazine” listed Mount Calvary as one of the 100 fastest-growing U.S. churches after completing a church growth study.
