About

Senior accounting professional leader focused on driving financial function efficiency and impact in dynamic, high-growth environments. Background in full-cycle U.S. GAAP accounting, multi-entity financial reporting, and process infrastructure — with experience across DTC ecommerce, client advisory, and B2B financial services. Track record of stepping into ownership roles, identifying gaps, and building the processes and controls to close them. Most recently served as Senior Accountant at a DTC apparel company, owning the full month-end close cycle, leading an offshore accounting team, and building out the file governance and controls environment. Prior to that, I led a 10-person global team delivering end-to-end accounting and financial reporting services across a 7-entity, $300M+ client portfolio at a CAAS firm. Core competencies include month-end close ownership, account reconciliation, variance analysis, financial reporting, internal controls, and cross-functional team leadership. I hold a Bachelor's degree in Economics from the University of California, San Diego, am fully eligible to sit for CPA exams, and am committed to pursuing licensure in 2027.
