Personal Note

Mike is a Southern California native and lives in Rancho Cucamonga with his wife and two young daughters. Always up for adventure, Mike has hiked to the top of Mt. Sinai, been inside the Pyramids of Egypt and experienced the top of the Matterhorn. As he “convinces” his young family to join him in his passion for sports, especially the Lakers, and outdoor recreational adventures – like off-roading in Glamis, he is also known as being a pushover for a good bedtime story.
