Dan P. Weinstein began his career in security when he was only a boy in grade school. He licked stamps and stuffed envelopes for his father's company, Russian River Property Patrol.  Russian River Property Patrol began its operations on the Russian River in Guerneville, CA checking the summer cabins at night during the off season in the late 60's. It quickly grew to be the largest, locally owned and operated security service company in Sonoma County.

Dan's experience in the Security Industry is unmatched in the North Bay counties. He has built relationships with clients and employees alike with his knowledge and integrity in the field. Upon his father's retirement, and after 25 years in the industry, Dan formed Weinstein Security, Inc., with his wife, Maureen. At that time, Maureen had over 10 years experience in the industry, and received BS degree in business administration and accounting. Maureen is also a Certified Public Accountant (CPA), which gives Weinstein Security, Inc. a unique quality.
