Mary Ann O'Connor

The most wonderful woman in the world passed away Tuesday, March 27, 2018. Nobody has ever fought the evil cancer battle as hard and as long as "Mairz", but after a 25-year fight, she succumbed in the comfort of her Sunset Cliffs home surrounded by her loving, immediate family of eleven.

Mairz was born April 25, 1947 in Denver, Colorado, to Herb and Agatha Kullman. She was preceded in death by her parents and sister, Debra and is survived by her brother, Fred of Santa Fe, New Mexico. She was born and raised a Rocky Mountain girl - an expert skier, mountain wilderness hiker, and trout fisher lady. After graduating from Saint Mary's Academy in Denver, Mairz entered the University of Colorado, Boulder, and graduated with a B.S. in Psychology. While there, she met and married the love of her life, Bill O'Connor. They spent 48 wonderful, fun years together - along the way raising two amazing children, Kelly Jean and Chad Hogan and five beautiful grandchildren. Tom and Kelly Conway (née O'Connor) live in Carmel Valley with their children Matt & Kate. Chad and Lisa O'Connor live in Point Loma with their children Logan, Landry and Tatum.

Mairz spent most of her adult years in San Diego, moving from Denver in 1975 with Bill to raise their young family. Once settled, there was not a sport or activity she wouldn't try and succeed wonderfully at. She worked up to the Ladies Open Division Soccer competition, became an avid windsurfer, long distance runner and tennis player. Along the way Mairz was passionate about raising her family and actively participating in her children's activities. There was not a child's activity she didn't help at and/or lead including, serving as president of two PTA's and coaching boys youth basketball and girls youth soccer. Mairz final real passion became golf. In spite of a late start in her 50s, she was soon playing regularly in the low 90s and served as president of the Coronado and La Jolla Country Club Woman's Golf Clubs. Her smile, zest for life and engaging personality will be missed by all who knew her.

A celebration of life will be held on April 22, 2018 at La Jolla Country Club. In lieu of flowers, donations may be made in Mary Ann O'Connor's memory to: Saint Mary's Academy 4545 S. University Blvd. Englewood, CO 80113 303-783-6227

Bill, Kelly, and Chad,
I just heard the news today about Mary Ann. I have many memories of her. My heart is heavy... You were my favorite family to babysit for. She was an incredible mother, wife, and friend. She gave me lots of good advice, and a spaghetti recipe that I still use, in her handwriting. She even trusted me to drive her VW squareback...she was the coolest! I will always remember her and your family.
Take good care,
