"Peter A.S. Pfeiffer Sr., age 63, passed away on November 25th, 2022 after fighting a long and courageous battle with cancer.

Born on September 17, 1959 in Baltimore, Maryland to the late Alexis and Peggy Pfeiffer.

Peter impacted the lives of so many. His character, integrity and genuine caring was a light to those who knew him. Peter was always a fighter. He served as a Lieutenant in the 82nd airborne division. While he left active duty, he joined an Army Reserve unit and became Special Forces qualified. Peter volunteered many hours promoting Folds of Honor to help children of veterans. Peter was a dedicated coach for his daughter and son's sports teams where the term ""Lean Forward"", one of his favorite phrases, was born.

Peter lived his faith. He demonstrated his faith through the way in which he lived and treated others. He was a rock - a warrior - a man of God. Peter hosted many home groups, served as an elder in his church, and was a missionary who traveled across the world to help those in need and spread the word of God.

Peter enjoyed reading book after book, journaling, spending nights playing games and watching movies and shows with his beloved family, and spending time outdoors. Peter was known to wake up before the crack of dawn. Before everyone else would wake up, he would send daily text messages to his children, work out for hours, and take his beloved Golden Retriever, Mo, on a walk. He'd always make just enough of his daily morning oatmeal so Mo could have his leftovers.

Peter was an incredibly loyal team member for his company that meant so much to him, RSM. He would want everyone at RSM to know that the time served with his company include some of his best memories and fondest relationships.

His love for his family and others who were blessed to be part of his life was steadfast. He is survived by his loving wife, Kristina Pfeiffer; his daughter Tiffany and his son Peter Jr, his Golden Retriever, Mo, two brothers, Walter Pfeiffer and Dale Pfeiffer; and also survived by one nephew, AP Pfeiffer.
