James L. “Jim” Siebenmark, 81, of St. Joseph, passed away on Saturday, November 14, 2020, at Spectrum Health Lakeland. Due to the current COVID-19 pandemic, the Celebration of Life Service will be held at a later date.

Jim was born on January 22, 1939 in New Buffalo to Fred W. & Della (Hamann) Siebenmark. He graduated from New Buffalo High School in 1957. After graduating, Jim proudly served our country by enlisting in the United States Marine Corp. On May 26, 1961, Jim married the love of his life, Betty Beck, in New Buffalo. They were happily married for nearly 59 years before she passed away earlier this year. Once his military duty was completed, Jim began his career as a police officer. He worked for the Berrien County Sherriff’s Dept. for two years, followed by 25 years for the City of St. Joseph Public Safety Dept., and another ten years as a Berrien County Court Officer before retiring. He was a member of The F.O.P. #96 and Three Oaks Masonic Lodge #239. Jim enjoyed hunting, fishing, riding his bike, and taking walks around town. He also liked watching Western movies and reading, especially about military history. What Jim loved the most, however, was spending time with his grandchildren.

Jim is survived by his children, Susan (Ed) Johnson of Cincinnati, OH, and Michael (Kevin West) Siebenmark of Kalamazoo; grandchildren, Nicholas (Sarah), Alexander, Jack and Ellie Johnson; and many nieces and nephews.

Jim was preceded in death by his parents, Fred & Della; loving wife, Betty; and siblings, Ray, Dale, and Gene Siebenmark, and Carol Fellows.

Susie & Mike, my condolences in the loss of your dad. I had a lengthy phone conversation with him a few months ago. Jim and I were school chums - played in the band together, hung out and I corresponded with him when he was in the Marines. You always knew where you stood with him as he was upfront, honest and just a good guy. Sure glad I connected with him with what turned out to be the last time I would talk with him. May the dear Lord be with you as you go through the loss of both your parents in such a short time. Sharon Sandera, Westminster, CO

Knowing and working with Jim during our law enforcement careers was truly an honor.
Jim always set the bar of honesty and integrity high for law enforcement.
I will truly miss you my friend.

While serving as a judge with the Berrien County Trial Court, I had the privilege of serving with Jim. He was very knowledgeable, able to work with people from all backgrounds, and most of all, a gentleman. He demonstrated these qualities throughout his entire career. Berrien County is a better place because of the talents of Jim Siebenmark. My thoughts and condolences are with his entire family.

I’m really going to miss Papa. He’s been around me my entire life, and I couldn’t ask for a better grandfather. Him and Grammy would come down to visit a few times a year and almost every time they did Papa and I would make a time to go to breakfast, it was our thing. We’d have a great time eating good food and having good conversations. He always joked that we would be doing it even if
I had to push him around in a wheelchair. This year has been a struggle so we never got to go. I loved listening to his stories, talking to him and just being around him. I am truly going to miss him, life won’t be the same without him.

I knew Jim in high school , We reconnected about ten years ago and kept quite a correspondence going while the old NBHS forum was still in existence. RIP old friend Pat Tyron

What a terrible loss to all of us with the passing of Betty and now Jim. Two wonderful, honest, loving, hardworking and genuine people. Such great role models for people growing up around them. Jim was wonderful to work with. He was even tempered, efficient, organized and knowledgeable. He was also a bit of a stinker with that smile and wicked quick humor. He kept you on your toes, kept you thinking and challenged with excellent conversation, and he looked out for all of us with kindness. Life was never dull with Jim around. Now he and Betty are back together. Thanks for everything Jim. Peg Penninger, Prosecutor's Office and criminal defense, retired.
