Mark spent the first half of his career working in a wide variety of law enforcement and investigative roles.  Starting in federal law enforcement in San Diego, Mark then took a transfer to Portland where he met his now wife of 16 years the first day he arrived- a good move for sure.  He transitioned to municipal police work for the City of Sherwood and later ran the Oregon Humane Agent program, a small law enforcement unit enforcing animal cruelty laws based on the Oregon Humane Society.  These positions and the great variety of experiences came into play well when he became a Crime Prevention Program Coordinator for the City of Portland and worked on diverse and challenging chronic crime and public safety issues and locations.  Mark worked for a little over a decade in almost every neighborhood and business district in the City.  He partnered with many city, county, and non-profit organizations to facilitate community programs such as livability teams, neighborhood, and business crime prevention programs, and provided a host of public safety resource trainings to diverse community groups.  Mark believes passionately in the power of building community and long-lasting and genuine relationships and partnerships.
