My mission is to empower individuals and organizations to navigate today’s complex digital world with confidence through innovative training solutions and cybersecurity awareness initiatives. My journey has been shaped by a blend of international relations, business development, and entrepreneurial ventures. My dedication to international cooperation is reflected in my work with Greater Fort Lauderdale Sister Cities International (GFLSCI), where I spearheaded the sister cities partnership between Constanța, Romania, and Fort Lauderdale, FL USA. I managed relationships between the city halls, facilitated communication, and organized inbound delegations from Romania, fostering cultural and economic collaboration. As a community leader, I’ve advanced women in tech through engaging programming, promoted English literacy for at-risk youth through the BorderlessBooks initiative, and created the International Women Authors event to celebrate and inspire women writers globally. Beyond Cyber Qubits, I serve as the Honorary Consul of Romania in Colorado, where I established the first honorary consulate in the state. In this role, I work to strengthen diplomatic, cultural, and economic ties between Romania and the U.S., fostering collaboration and building lasting connections.
