first husband Roger Stein. During their 17 years of marriage, they had three children, Craig, Mark and Resa. After her divorce, Marlene was working for the Navy as a civilian and received a scholarship from the Navy to go to college where she earned a bachelor’s degree in Communication and Information Sciences from California State University, Chico. She then met her second husband Dan Siegel and moved to the east coast where see went back to school and earned a Masters’ Degree in Applied Psychology and then went on to earn her Doctoral Degree from the University of Phoenix. She divorced her second husband in 1994 and focused on her work as a civilian employee for the Navy. In 2012 she retired from a civil service career with the US Navy that included more than 35 years of general services and contract work, which covered a variety of locations including Washington DC; San Diego, CA; Guam, USA; Monterey, CA; Fallon, NV; and Sicily, Italy. During her many tours of duty, she has held several key positions including video producer, administrative officer, educator, marriage and family therapist, and Fleet and Family Support Center Director. While in Sicily, she collaborated with Chuck Underwood (author of The Generational Imperative), to transform his research into intervention guidelines for mental health care and medical care for service members returning from the war zone. Her presentations were utilized and valued throughout the Navy system. She also
completed research in Italy that paired military attrition with generational core values. This research changed the face of recruitment for the European Theater.

  • Marlene started out as my professor, and later become my therapist. She was such a joy and beautiful inside and out. She helped me through some of my darkest hours and shined light on the good in my life and helped build me back up. I am so greatful to have met her and had her in my life. The sorrow I feel at her loss is intense but in so grateful she’s no longer struggling. She now is shining down on all of us. I’m gunna miss u so much!
