Mark was born in Kingston Pennsylvania as one of triplets—he had two female womb-mates. His first uniform was Boy Scouts leading to Eagle Scout. At 18, he was accepted to the United State Military Academy where he was an All-American Wrestler and donned another uniform as a cadet.
The day after graduation from West Point, he married his beautiful wife Carole and they have four wonderful daughters. He served in an Infantry Battalion of the 101st Airborne Division in Vietnam. Their family occupied seventeen different abodes in the U.S and abroad as they moved from post to post seeing the world and working with great leaders like Colin Powell. He retired as a Colonel.
Upon retirement, he spent twenty-six years facilitating management/leadership workshops throughout the U.S., Canada, and Europe. His clients include Fortune 500 companies such as Lucent Technologies, United Airlines, Wal-Mart, and AT&T as well as organizations as diverse as Underwriters Laboratories, the Internal Revenue Service, the National Park Service, state and local government and more.
He has spent countless volunteer hours devoted to making the lives of people with disabilities better, and with his outgoing personality and kindness, he has made many friends all over the world. He loves to travel, make new friends, golf and loves the outdoors. In his free time when he's not working on his book, Mark enjoys walking his dogs, volunteering in the community, spending time with his family and fortunately still loves yard work!
