With the arrival of the post war years and the rapid economic changes that accompanied them, St. Philip’s once again experienced explosive growth. Church membership grew by over fifty percent between 1945 and 1955. Several improvements were implemented to better serve the expanding parish. Money from the Toucey Fund was used to install a new organ in 1957. Communications were improved through the introduction of a weekly bulletin and in 1958, the 150 year old practice of pew rentals was abolished. (Funds for church programs during its early years were raised through annual rentals of pews to families for their exclusive use.). In 1959 vestry elections were first opened to women.

Some important milestones reached during the time of growth for women in the U.S. included the first woman minister to serve St. Philip’s when Ann Wevling , the sister of Ruth W. Anderson, served the church from 1991-1992. The Vestry, with a tradition of over 200 years, installed Jan Spaulding, who was elected as the first woman to serve as Senior Warden of St. Philip’s. In 1996, the Right Reverend Catherine Roskam became the first woman Bishop to visit St. Philip’s.

In 1960, the Reverend William Reisman became rector of St. Philip’s Church. Mr. Reisman served the congregation with distinction for twenty-seven years and was beloved both in the congregation and by the community. During his leadership the Parish House was modernized, the rectory and sexton’s homes were redecorated, flood-lights were installed, and the stained glass windows in the church were restored and fitted with protective covers. Adult education classes were initiated and the Parish House became a focus for community activities. Drawing upon Dr. Chorley’s historical texts, Mr. Reisman updated the history of St. Philip’s Church to the 1970’s.

With the arrival in August, 1987 of the 217 year history and traditions of St. Philip’s were commended to a strong stewardship. During this era of the closing years of the 20th century, Francis H. Geer has St. Philip’s has guided the spiritual lives of the parish through years of rapidly changing times within the immediate area and throughout the greater U.S. He has expanded church activities, widened the community outreach services of St. Philip’s and pursued a gradual and steady course of improvement of the church land that is respectful of St. Philip’s magnificent history and development.

Under Frank Geer’s guidance, the Parish House roof and interior floor have been replaced, the Ruth W. Anderson memorial garden was constructed at the north end of the Parish House and serves as a greeting center after the Sunday 11:00am service, the organ was restored and additional antiphonal organ pipes were installed and a beautiful grand piano was donated to the church. During these years, Rev. Geer has always made the Parish House available to Garrison community groups. A few of the organizations that have used the facilities for temporary quarters include: the Ambulance and Fire Corps., the Audobon Society, the Boy Scouts and Girl Scouts, the Philipstown Youth Theater which is now at the Depot Theater and the Garrison Youth Center which is now located across the street at the Garrison Elementary School. The Nursery school of St. Philip’s, now in its fifth decade, continues as a vibrant center for the youngest parishioners.
