Michael "Mikie", "Pops" Hagan, passed away on October 19, 2022 after a short battle with lung cancer.  Mike was born on August 19, 1947 and was adopted by Ray and Patricia Hagan.  Mike is survived by his two sons, Patrick (Samantha) and Christopher (Allison),  former wife Robin, grandchildren Kaylee, Nathan, Clayton and Hattie, sister Tammy Davidson, nephews Shon and Brian Delia, along with close friends Jan Schwartz and Linda and Byron Atwater,  just to name a few, and his beloved dog Zoey.

Mike served in the Air Force during the Vietnam War refueling aircraft in flight.  After his tour of duty ended, he attended UC Berkeley where he received a Bachelor's Degree in mathematics.  He became a software engineer and retired on 12/31/2019.

Mike's pastime was staying fit and being healthy.  Through the course of his life, he ran many marathons, triathlons , and rode countless miles on his mountain and road bikes with family and friends.

Mike volunteered for East Bay Regional Parks Search & Rescue, and taught First Aid and CPR.  He took joy in passing along his knowledge to others and helping people when he could, and was a devoted father, grandfather, brother, uncle, friend, co-worker and teacher.  He had a great big smile, a wonderful laugh, and a quick sense of humor. He will be greatly missed.

The family requests that donations be made in honor of Mike to the Valley Humane Society, 3670 Nevada St., Pleasanton, CA 94566 in Mike's name.

A Celebration of Life will be held for family and friends.
