The first church edifice was a small-frame building located on what is now known as Chancellor’s Run Place in Nanjemoy, Maryland.  As souls were saved and added to the church, the need for more space became eminent.  In 1901, the church was rebuilt in its present location on Holly Springs Road in Nanjemoy, MD.  Rev. Gaynor served as Pastor for approximately 18 years and upon his death was succeeded by Rev. R.B. Ward.  Rev. Ward served as Pastor for approximately 20 years and was succeeded by Rev. Garfield Hunter who was installed on June 19, 1921.   

During the pastorate of Rev. Hunter, the church vestibule was repaired and the outside of the church was whitewashed.  Rev. Hunter served as pastor for approximately two years, after which Rev. George Carter was called to assume the pastorate.  During his pastorate, several deacons were ordained and the annex (hall) and choir stand were added to the church edifice.  Oak Grove became known as the “Holy Ghost Headquarters.”  After Rev. Carter’s faithful 29 years of service, God called him from labor to reward. 

On May 17, 1953, Rev. Herbert Holmes was installed as the pastor and under his leadership a basement was added, a furnace installed, and new flooring was put down.  Rev. Holmes served for eight years and returned home to Chicago for personal reasons.  Rev. Joseph Washington served as the acting pastor during this transition.  In search of a new pastor, Sister Naomi Johnson invited Rev. William Leach to preach and Oak Grove realized that their faithful prayers had been answered.  Rev. Leach was installed as pastor in June 1960.  Under the leadership of Rev. Leach, indoor plumbing was installed in the church, and the pastor’s study and finance room were added.  A choir room and kitchen were also installed. Rev. Washington continued to serve as the Assistant Pastor until his health began to fail. From 1973 to 1976, Rev. William Thorpe then served as the Assistant Pastor.   

On May 1977 complete renovations of the church began.  Services were held in the hall adjacent to the church and occasionally at our neighboring churches.  The church continued to grow in membership.  During this time, Trustee Sedrick Cobey designed the church and led in the construction of a new church edifice in which Oak Grove currently worships. The construction of the church was completed in 1981.  The dedication service was held on April 26, 1981. Since that time, through the help of God much progress was made.  Various individuals and groups contributed to the necessities of the church providing trays, kitchen appliances, dining room chairs and tables, etc. The baptismal pool was completed August 25, 1984, and the mortgage burning was celebrated on April 24, 1988.

Rev. Leach’s health began to fail him and from time-to-time he made every effort to come and be on his job for the Lord.  God knew that Rev. Leach needed an assistant, so the Lord sent Rev. Lowell H. Hancock who joined the church in September 1988 and became the Assistant to the Pastor.  On November 25, 1989, the Lord called Rev. Leach from labor to reward.  He served faithfully for 29 years as Pastor of Oak Grove.  Rev. Leach will be remembered as a loving, devoted, and faithful Pastor.

For approximately one year and eight months, Oak Grove was without a Pastor.  During this time, Rev. Hancock assisted in performing the required pastoral duties.  Recognizing his service, Rev. Lowell H. Hancock was elected as pastor on June 2, 1991.  Rev. Hancock was installed on July 28, 1991. During his pastorate three deacons were ordained, seven trustees added, and the By-laws and Constitution were revised and the church incorporated.  In addition, improvements were made to the church cemetery, church property was cleared for recreation, an organ was purchased and a handicap ramp was installed.  Rev. Hancock served for 18 years.

On April 9, 2011, Rev. Alvin W. Dockett was elected as the eighth Pastor of Oak Grove.  Within the first month of assuming the pastorate, 30 souls were baptized into the Kingdom and over 50 new members were added to the church.  Since being elected pastor, two deacons have been ordained, two trustees have been appointed and the By-laws and Constitution revised. Rev. Dockett has also lead the church in capital improvements including renovations to the bathrooms and vestibule, renovations to the pastor’s study, the construction of a new audio/visual sound room, and a bathroom and office space was added in the lower auditorium.  In addition, under Rev. Dockett’s leadership, a handicap-accessible ramp was added, and renovations were done to the sanctuary including the construction of a new pulpit, new carpet, and new windows.  In January 2013, Rev. Melvin Latimer was appointed as the Assistant Pastor of Oak Grove. He faithfully served assisting Rev. Dockett and leading the Men’s ministry. 

In July 2014, Rev. Alvin Dockett was called to another church. During this transition, the Deacons and Ministerial Staff proudly and faithfully served the congregation until October 2014.  At which time, Rev. Joseph C.T. Flippin was elected and served as the Interim Pastor.

On August 2, 2015, Rev. Flippin was installed and served as the Pastor of the Oak Grove Missionary Baptist Church until his resignation on December 30, 2018. Under his pastorate, many souls were saved and added to this Body of Christ.  During his tenure, he ordained two Ministers, Rev. Roland Butler and Rev. Gwendolyn Warren-Washington and one Deacon. Rev. Flippin later appointed Rev. Gwen Warren-Washington as the Assistant Pastor. He also developed a Young Adult Ministry. Under his leadership, 3 large projector screens were installed in the sanctuary and early morning corporate prayer was established by way of conference-call.

Oak Grove stands in great expectation as we turn yet another chapter in the life of this branch of Zion. To God Be All The Glory!!
