Sheriff Reggie Marinelli

Thank you for taking the time to learn more about the Jefferson County Sheriff’s Office (JCSO) and our Strategic Plan. It is my privilege to share this 5-year Strategic Plan with you—a plan built through meaningful collaboration with our diverse communities, valued stakeholders, and dedicated staff. Together, we have laid a strong foundation that will guide us in achieving our vision: to make Jefferson County a safe and welcoming place where everyone can live, learn, work, and play.

At the heart of our organization is a deep commitment to community. We believe that by engaging directly with our residents to shape programs, deliver services, and make important decisions, we build stronger relationships and foster a shared sense of purpose.

As we implement these initiatives and meet our objectives, we will celebrate those successes together.

The dedication and professionalism of the men and women of the JCSO continually inspires me. Every day, I see firsthand their unwavering commitment to serving our community with integrity, excellence, and respect. Having served with the JCSO for almost forty years and taking on the role of Sheriff in January 2023, I am deeply honored to lead this exceptional team.

We look forward to working alongside you as we fulfill our mission to protect, serve, and enforce — always in partnership with the community we are proud to call home.

Strategic Plan Development

The JCSO Strategic Plan was developed under the direction of the Research and Planning Commander, with guidance from the Sheriff and Undersheriff.

The process began with establishing a guiding philosophy from agency leadership. Best practices were then reviewed, including strategic plans from other law enforcement agencies of similar size. Unlike previous plans, this version outlines strategies by division to better reflect the wide range of services each provides to the community and to internal partners.

Organizational strategies were set by the Sheriff, Undersheriff, and executive staff through collaboration with stakeholders. Each division — Detentions, Patrol, Investigations, Support Services, and Strategic Services — then created division-specific strategies that align with the agency’s overall goals.

To identify priorities, the Research and Planning Commander led a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis with leaders from every part of the organization. From this, draft goals were developed and refined.

Community input was an important part of the process. The Sheriff’s Office Citizen Advisory Council contributed through a workshop and survey that highlighted expectations, concerns, and community strengths. Additional feedback came through the Office of Public Affairs, which monitors public sentiment on social media, responds to about 1,200 public inquiries annually, and relays concerns to the executive staff. Community surveys from the PowerEngage platform, which gathers feedback after calls for service, also informed the plan.

Finally, the command staff reviewed all input to identify key priorities, evaluate challenges, and develop strategic initiatives. These discussions helped set the direction for JCSO’s work in the years ahead.

Jefferson County is known for being a beautiful place to live, learn, work, and play. The county is home to diverse landscapes to include mountains, plains, and foothills that line the eastern edge of the Rocky Mountains. Just minutes from downtown Denver, Jefferson County enjoys easy access to all major arterial highways and other modes of public transportation.

Our county seat is the City of Golden. This is also the location of the Jefferson County Sheriff’s Office Headquarters (North Precinct), the Detention Facility, and the Jefferson County Courts and Administration. Jefferson County, the “Gateway to the Rocky Mountains,” has an estimated total resident population of 578,533, which is projected to increase by 9.4% by 2050. The Sheriff’s Office provides law enforcement services in the unincorporated areas with a population of 199,548 residents, along with support to the many municipal law enforcement agencies within the county. It is the fourth most populous county in the state. Other population dynamics include an influx of travelers through the county via major thoroughfares, and a substantial tourism population that attends many of our large special events and destinations throughout the year.

Our county has an abundance of national, state, and local parks, forests, and open space areas. The Jefferson County Open Space program has over 50,000 acres of land dedicated to preserving the Rocky Mountain environment for future generations. These Open Space Parks receive about seven million visitors annually.

Prioritize ongoing training programs for law enforcement personnel (sworn and professional) focusing on de-escalation techniques, cultural competency, and the use of new technologies. Promote career opportunities through succession planning for lateral and promotional moves.

Mental Health Support

Implement programs to support the mental health and well-being of employees, including physical fitness, nutrition, spiritual, financial, and counseling services, as well as stress management resources.

Strategic Plan Implementation & Accountability

Strategic goals will be reviewed quarterly, with a comprehensive evaluation conducted annually during the Jefferson County Sheriff’s Office (JCSO) Divisional Leadership Retreat.

As we move forward, the Jefferson County Sheriff’s Office remains firmly committed to continuously improving our operations — both internally and in how we serve and engage with the public. Sheriff Marinelli and the entire JCSO team are dedicated to transforming the priorities outlined in this plan into measurable action, always guided by our Mission, Vision, and Core Values.

This strategic plan is designed to be a dynamic, practical tool — not a static document. It provides a clear framework to guide our daily work while ensuring accountability through centralized tracking and regular progress reviews. Each year, during our dedicated three-day Leadership Retreat, JCSO command staff and supervisors come together to evaluate our progress, share insights, and refine the plan based on evolving community needs and emerging best practices in law enforcement.

It is important to emphasize that this document does not constitute policy or procedure. Rather, it articulates our strategic priorities, defines areas of focus, and supports transparent progress monitoring to ensure we consistently deliver the highest level of service to the residents of Jefferson County.

Workload analysis cycle

Every three years, the Sheriff’s Office conducts a comprehensive workload analysis as part of our ongoing staff inspection process. This structured review evaluates our operational practices and staffing needs. The process emphasizes collaboration and engaging directly with the personnel in the units, sections, or divisions being assessed to ensure a realistic and informed analysis.

Over the past 25 years, our professional staff numbers at JCSO have crept upward only slightly, while our sworn deputies have struggled to keep pace with rising demands. Until recently, funding limits meant we could only add eleven deputies to the Patrol Division — from 175 in 2000 to 186 in 2024 — even as call volumes increased, investigations grew more complex, and technology drastically increased the collection of records and evidence. Today’s calls for service take longer and require more specialized knowledge due to evolving technology, more complex criminal behavior, and expanded state and federal mandates.

Thanks to our voters, the future of the JCSO looks much brighter. In November 2024, Colorado approved a statewide initiative that will funnel new dollars into law enforcement recruitment, training, and retention starting July 2026. And here at home, Jefferson County residents passed Ballot Measure 1A, opting out of strict TABOR revenue limits so the county can retain more of the taxes citizens already pay. We’re deeply grateful for this trust — and for the critical safety infrastructure it brings.

With the passage of 1A, Jefferson County is investing nearly $7 million in wildfire mitigation and response, adding 37 dedicated wildland fire staff. At the same time, the Sheriff’s Office can fill dozens of previously vacant sworn and professional positions. That means more deputies on patrol for faster response times, more behind-the-scenes specialists to handle complex cases, and an overall boost in law enforcement capabilities to protect our neighborhoods, schools, businesses, and people.

These developments arrive just in time for a full agency-wide staffing assessment as part of our staff inspection process. With potential new funding on the horizon, we’ll dive deep into operational practices and personnel needs — talking directly with folks in every unit and section to make sure our recommendations are grounded in reality. Our employees remain as committed as ever, and strong public feedback collected through surveys and community engagement confirms that you stand with us. Together, we’re building a safer Jefferson County for everyone.

Summary

This Strategic Plan defines the Jefferson County Sheriff’s Office’s mission, long-term vision, and strategic direction. It reflects our commitment to public safety, community trust, and continuous improvement in how we serve and protect.

The plan sets out key goals that will guide decision-making across all levels of the agency — from daily operations to long-term initiatives. It is intended to be a resource for current leadership and future generations of JCSO personnel.

Recognizing that public safety is always evolving, this plan is designed to grow and adapt over time. It will be regularly reviewed to ensure it remains aligned with emerging trends, local needs, and our pursuit of excellence. Through this approach, the JCSO will continue to be a responsive, modern, and forward-thinking agency that is relied upon and trusted by the community.

Closing Message

As we conclude this strategic plan, we want to thank you for your continued support, trust, and partnership. Your involvement in public safety — through your engagement, your feedback, and your votes — makes our work possible. The Jefferson County Sheriff’s Office is here to serve you, and we take that responsibility seriously.

This plan reflects our ongoing commitment to transparency, accountability, and continuous improvement. It is built on the belief that when law enforcement and the community work together, we create a safer, stronger, and more resilient county for everyone.

Thank you for standing with us. We look forward to the years ahead — working side by side to protect and serve our community with honesty, accountability, excellence, honor, and respect.
