John Gerard McWilliams, 78, of Denver, Colorado, passed away peacefully on August 29, 2023, after a long battle with Parkinson's disease.

John was a visionary in the real estate market in the Denver Metro area. He founded Western Skies, LLC, bringing to Denver the medical campus model. He was a passionate golfer and runner, and he always found a way to give back to the community through his charitable contributions.

John will be remembered as a loving husband, father, grandfather, and great-grandfather. He will be deeply missed by all who knew him.
