City Manager @City of North Miami Beach

North Miami Beach, FL, US

As City Manager of North Miami Beach, I led a full-service municipal organization with over 500 employees and a $212 million budget, driving fiscal discipline, operational modernization, and equitable community development. Under my leadership, the City secured an AA bond rating—enhancing its financial standing—and transitioned to a Priority-Based Budgeting model supported by the launch of Socrata Open Finance, updated the City\'s reserve Fund Balance policy as well and CIP funding policy while greatly improving transparency and accountability.I directed more than $72 million in capital improvement projects, including critical upgrades to water and stormwater infrastructure, facility enhancements, and citywide resiliency initiatives. To accelerate delivery and enhance project management, I established a standalone Capital Improvement Department and realigned internal leadership structures to strengthen performance and accountability across departments.I successfully negotiated collective bargaining agreements with both general employees and the police union, bringing wages and benefits up to industry standards with near-unanimous union approval. I also secured over $9 million in external funding for youth enrichment, mobility innovation, and park redevelopment—including the completion of a community park project that had been promised for decades.Through collaboration with federal, state, and regional partners, I advanced Smart City initiatives, pursued federal clean energy infrastructure funding, and led environmental remediation efforts to prepare key public lands for future redevelopment. Our improvements to the FEMA Community Rating System resulted in a 15% reduction in flood insurance premiums for residents.
