Pastor Meister concluded his service in 1964 to start a mission congregation in south Fairborn; the Rev. Donald Brown became St. Mark’s new pastor.  Early in 1964 the mortgage for the parish education building was burned, and the congregation busied itself to refurbish the church and parsonage for the new pastor and his family.  Twenty-two volunteers painted the interior of both the church and the parsonage.

The director of music, Mrs. Roger (Linda Shoaff) Boyd, felt strongly that it would be best to move the choir from the left side of the chancel to the balcony.  To do that required that the organ be moved and, if possible, be replaced with an electronic instrument that did not require the fatigue of pumping.  The congregation rallied and an Allen electronic organ was purchased and placed in the balcony.  One family contributed a gift to install air conditioning for the sanctuary.  In addition, risers were placed in the balcony for the choirs.  A wall-to-wall communion rail with a kneeler was made feasible after the choir moved from the chancel.  The right side of the chancel was opened by removing the partitions which formed a chancel storage area.  Pew kneelers and cushion seats were added to all the pews.  A new pulpit, lectern, baptismal font, and a free standing altar were purchased.  New lighting was installed and green carpeting was added throughout the chancel, on the aisles in the nave, and in the narthex.  Baseboard hot water heating was installed throughout the nave.

Two structural changes were also made.  First, a new main entrance at ground level with inside stairs leading to the narthex was constructed.  That change also required that the steps from near the kitchen on the ground floor to the west narthex be reworked.  Second, a glass wall with glass doors was installed at the rear of the nave to provide for overflow seating in the south narthex.  It was also suggested that new mothers could use the south narthex a  “cry room.”

Dedication of the new furniture was held on Jan. 26, 1969.  Also during 1969, after the departure of Pastor Don Brown, council sold the parsonage at 17 James Drive.  Pastor Gordon Glink and his wife, Dorothy, gave preference to a housing allowance in lieu of a parsonage.

Each of the following three years saw some addition or improvement made to the church.  In 1971, a bequest by Anna Herr permitted a committee of women to purchase new furniture and to redecorate the church lounge.  During that same year pews were purchased and installed in the balcony for the choir.  Chimes were added to the bell tower in 1972. Memorial gifts permitted the addition of a sanctuary lamp and an Advent wreath with a Christ candle to the chancel.  A new piano was gifted to the church that year and window air conditioners were installed in the pastor’s and secretary’s offices.

The Facilities Improvement Project (FIP) was the vision of David Shober and his Property Committee.  In 1994-1995 the congregation approved and provided pledge support for three major projects.  First, an elevator was added to provide access for the disabled.  That was placed in the west narthex and required giving up stair access to one of the exterior doors.  Second, Michael Hammond gave leadership to the installation of new carpeting in the nave and both narthex areas.  The third focus of the FIP was to provide a new sound system for the church which included audio enhanced equipment for the hard of hearing.  Ron Rohm chaired that portion of the project.

In 1996 bricks in the bell tower were found to be unstable.  An inspection further revealed that there were many other areas of the masonry which required tuck pointing.  The compelling safety issues brought a congregational vote to proceed  with the project.  About $37,000 was expended for cleaning and the necessary tuck pointing of the brick and stone.  Scott Pelfrey, Property committee chairman, gave leadership to that improvement.

After the installation of pastor Robert Forsberg in 1997, an allocation from the memorial fund was used to repaint, re-carpet, re-drape and purchase some new furniture for the pastor’s office.  The secretary’s office also had new window treatment at the same time.  Clermont Brown helped to expedite those activities.
