In California, Administrator Guzman oversaw a network of small business centers focused on expanding assistance to underserved business groups. She launched new public private partnerships and collaborated to deliver cutting edge resources to small businesses, including through initiatives like Get Digital CA to increase technology and e-commerce adoption and Source Diverse Source Local to strengthen supply chain readiness.  She advocated fiercely for financial relief for small businesses, leading to the expansion of state supported lending and the largest COVID-19 grant relief program in the nation at over $2.5 billion. Guzman's office launched the Entrepreneurship Task Force to serve as a bridge to small businesses and create content and programs to help strengthen the competitiveness of startup and small firms.

Administrator Guzman has previously served in leadership at the SBA as the agency’s Deputy Chief of Staff and Senior Advisor during the Obama-Biden Administration, where she oversaw policy and new program implementation. She was a small business entrepreneur herself, and an advisor to fellow founders including in accelerating technology commercialization and in helping small business contractors leverage the federal marketplace.  Administrator Guzman earned a Bachelor of Science from the University of Pennsylvania Wharton School of Business.
