Holy Trinity Episcopal Church began in the fall of 1899 when a small group of Episcopalians living in Dickinson appealed to The Right Rev. George Kinsolving, Bishop of the Dioceses of Texas, to send a clergyman to minister to them.  The Rev. A. J. Burnett, who was then in charge of a Mission in Alvin, found twenty-five people who helped to form Holy Trinity Mission and its first congregation.
 
The first three services were held in a private residence. Then a room at the Dickinson Fair Grounds building was temporarily used as the "church".  The Vestry of of Trinity Church Galveston supplied an organ and the first Sunday School was started.  In May of 1900 Bishop Kinsolving confirmed thirteen persons previously prepared by The Rev. Burnett.  In June of 1900 Mr. Joseph Lobit of Galveston donated a half block of land to build a church at its present location.  Another half block was purchased from Mr. Lobit for $250. In September 1900 the hurricane that devastated Galveston Island also destroyed the room where the Mission services were held, along with the organ, hymnals, prayer books, and altar hangings. In 1901 the Bishop gave funds to build the first church building and under the direction of The Rev. C, P. Dorset, director of a boy's school in LaPorte, the church was built. The congregation and the Dickinson community raised funds to partially furnish the church and the first service was held on Sunday, November 10, 1901.
 
Ministers from Trinity Church Galveston, Grace Church Alvin, Grace Church Galveston, St. Mary's Church Houston, and Holy Cross Church Harrisburg along with laymen served the Mission until July 1928 when the The Rt. Rev. Clinton S. Quin sent The Rev. Thomas S. Sumners to be the priest-in-charge.  During his leadership growth and interest were high, with a special interest on young people.  In November 1930, Rev. Sumners left to become the rector of St. John the Divine in Houston.  In the Spring of 1930 the first Strawberry Festival was held on the lawn of Mr. and Mrs. C. M. Wolston, Sr., primarily to entertain the young people of Trinity Church Galveston and the families of Holy Trinity.  The festival later became a community event and is held on the church grounds in May. In 1936 the Isabel Barnes Chapter of the Daughters of the King was formed.
 
During the Depression years and the early years of the Second World War the church suffered a decline, but still managed to construct the first parish hall for $450.  Army Chaplains from Fort Wallace and Fort Crockett helped the Mission to survive and thirteen people were presented to Bishop Quin for confirmation. In 1947 and 1948 a rectory was built and the second half of the parish hall was moved onto the property. Also in 1948 a small but active group of the Mission's members left to form a new mission, St. Michael's in LaMarque.
 
In the first fifty years of Holy Trinity the Mission recorded 123 baptisms, 126 confirmations, 25 weddings and 27 burials. In 1950 the Rev. David P. McBride came to Holy Trinity and under his leadership, growth was substantial.  In January of 1954 the 105th Diocesan Council granted parish status and the Rev. McBride was installed as its first Rector.  During his tenure, 96 candidates were presented to the Bishop for confirmation.  In 1955, another small group of parishioners left to form St. Christopher's Mission in League City.  During 1956 the Holy Trinity Church Building Fund was started. It had become necessary to make plans for a larger building since the facilities of the little original church were being used to capacity and extensive repairs were needed.  The Rev. Malcolm P. Riker of St. Michael's LaMarque was placed in charge of Holy Trinity.  He split his time between the two churches handling both business and parish visitations. He presented fifty candidates for confirmation to the Rt. Rev. Percy Goddard during his six months at Holy Trinity.
 
The Rev. George Welsch came to Holy Trinity in July of 1958.  Accomplishments were many during his nearly 14 years of service as Rector. In 1961 a six room Sunday school wing and a Youth room were completed.  The Weed "N" Wish Garden Club of Dickinson was begun at the church in 1961 with a nucleus of women from Holy Trinity. Dedication of a new church building was held in April, 1964.  When completed it had a seating capacity of 250, with room for expansion, and cost $65,000.  Dickinson's Ministerial Alliance and the Empty Stocking Fund were led for many years by the Rev. Welsch.  He was called to Christ Church Eagle Lake and conducted his last service during the week of Christmas, 1971.
 
The Rev. Paul Taft was rector for seven years beginning in April of 1972.  Under his leadership the congregation grew rapidly, especially young families with small children.  He helped supervise one of the most outstanding Sunday school programs in the community if not the whole Diocese.  The groundbreaking for a new 3000 sq. ft. parish hall was held in October of 1973 and dedicated as Wolston Hall in March of 1974.
 
The Rev. Tracy Wilder, III was rector for five and a half years beginning in l979.  He organized the Bethel Bible Series, witnessed the growth of the Church School and Youth Groups and initiated plans for a free-standing altar.
 
The Reverend James Hamilton became rector in 1985 and after 18 years of service left the parish on January 1, 2004. During his tenure the Sunday School wing was renovated and improved in 1987, a pavillion addition to Wolston Hall was completed in 1988, additions to Wolston Hall were made in 1989 and the parking lot was repaved, the Church Altar and Chancil were renovated and a new free standing altar was installed in 1990, and in 1991 drainage and cemetery improvements were made.  All windows in the sanctuary were replaced with stained glass and dedicated Sept. 1, 1991.  In the mid 1990's the roofs of the Sanctuary and adjacent buildings were replaced.  In 2002 the Church was recarpeted and painted and new pew cushions and recovered kneelers were installed, and the Memorial Garden, fountain and sidewalks were completed.  Rev. Hamilton was involved in ecumenism, CROP, and the ministerial alliance.  During his tenure he performed 167 Baptisms, 90 marriages, 155 burials and presented 167 members for Confirmation.
