Don was a remarkable man whose faith, devotion, and steadfast presence shaped generations. A loving husband, devoted father, and cherished grandfather, he lived each day with purpose, humility, and a heart anchored in service.

As a proud United States Army Veteran, Don carried the values of honor, discipline, and integrity throughout his life. He built a successful and respected career with Shorewest Realtors, guiding countless families through some of their most meaningful milestones.

At the center of his life was unwavering faith, which guided his decisions, strengthened his spirit, and inspired those around him. Don poured love into his family, leading with quiet strength, gentle wisdom, and a deep sense of responsibility. His grandchildren were blessed by his guidance, laughter, and unconditional support. He was loyal, steadfast, and held lifelong friendships, marked by the same sincerity and generosity he brought to every part of his life.

Don leaves behind a strong legacy rooted in love, devotion, and strong family ties. These values will continue to echo through the lives of all who were blessed to know him. His family takes comfort in knowing he is now at peace, welcomed into eternal rest, and reunited with those who went before him. His life was a gift, and his memory will remain a guiding light for all who loved him.

His master replied, 'Well done, good and faithful servant! You have been faithful with a few things; I will put you in charge of many things. Come and share your master's happiness!' -- Matthew 25:21
