A wedding is one of the most special times in a couple’s life.

To celebrate their big day, Gerard and Kathy Diemer exchanged their vows at Harrybrooke Park in New Milford.

This year, to mark the couple’s 30th anniversary, the couple recently renewed their vows — with the same wedding party — at the park.

“I really wanted to celebrate something good,” said Kathy of why she and her husband chose to renew their vows this year.

The celebration is, in many ways, the start of a new chapter for the couple, who lost their Sherman home to a fire in 2015.

Having lost everything — right down to treasured family photos of their daughter — and having spent a great deal of time navigating the stresses and emotions that accompany the loss of a home, the Diemers are forging ahead with optimism.

“We are truly blessed in every way,” Kathy said.

The husband and wife graduated from New Milford schools a year apart, Gerard in 1975 and Kathy in 1976.

Although they went through the school system together, they didn’t meet until 1982 at a party hosted by a mutual friend.

The couple dated for almost five years before marrying at the park on July 11, 1987.

Members of the wedding party returned for this year’s July 8 ceremony, with the exception of the late Clifford Chapin.

Joining the party this year were the Diemer’s two grandchildren, Aubrey, 7, and Emma, 2.

“The park is a symbol and we wanted to go back there,” Kathy said. “We love Harrybrooke Park.”

The Diemers lived in New Milford until 1992, when they purchased a home in Sherman, where they raised their daughter, Elizabeth.

Kathy has had a career in the auto industry, first selling cars at the former Hayes Chevrolet, then working in auto body and as a licensed auto damage appraiser and shop forewoman.

Gerard has worked in construction for many years. He spent many years working for a Long Island, N.Y.-based construction company, where he became fleet manager.

He eventually left there to open his own business, GED Fleet Service LLC, in 2012.

Following the house fire, Kathy left the auto industry to oversee the construction of a new home. Since then, she does bookkeeping for her husband’s business, teaches garden design, speaks publicly on a variety of topics and volunteers in the community.
