On June 26, 1966, Gary was the Officer in Charge of the USS Stalwart which was stationed in San Juan, Puerto Rico. A fire broke out in her forward engine room.

He also attended Mine Warfare School. In 1987, he went to Oberammergau, Germany to the Supreme Headquarters Allied Powers Europe where he attended The NATO school.

Gary has stated “Being named to command five Naval Reserve units was an ample reward in itself as it was an accomplishment very few Naval Officers have achieved."

In 1987, he took command of his last unit NR Saclant DET 118 in Kansas City, MO. He retired with the rank of Captain from the reserves on December 16, 1990.

Gary was extremely proud of his military career. He met his wife through being stationed in Puerto Rico. He was also able to travel the world and experience things that he wouldn’t have been able to do without his military career.

He had a long and successful career with VF Corporation. At one point in time he was in charge of handling the labor contract negotiations for over 12,500 employees. He was extremely proud that there was never a labor strike since he was able to work with both sides to agree on terms whenever the need arose.

Another love of Gary's was Zion Lutheran Church in Prairie Village, KS. He was a dedicated parishioner and made a multitude of lifelong friends during his years of attending.

Gary had a passion for fishing. He taught his grandchildren and countless other children to fish. He loved to golf and played in numerous golf leagues for years. His love for Missouri Football was near the top of his priorities every fall. He attended as many home games in Columbia as he could, even traveling to watch them play in some bowl games. He loved the heated rivalry of MU v KU. He also enjoyed rooting on his beloved Kansas City Royals. With his wife Maria at his side, he traveled often and was able to experience many parts of the world. 

Gary loved his family very much and spent as much time with them as possible. He especially loved spending time with his four grandchildren. he would take them fishing often, and was a constant presence at school functions or sporting events. They attended many Royals and Mizzou games together, and they were able to travel together around the USA on a few occasions. As they got older, he helped them learn about the stock market and advised them on their college admissions forms. He was always there for them.
