We are an experienced father and son team who has been leading the finance, accounting, and admin functions of nearly a dozen Silicon Valley companies for over 40 years combined. Our practice was established to serve small operations and startup ventures with personalized guidance and comprehensive back office support, and without the need, burden and cost of maintaining an in-house executive and admin team.

Today, Thomas works closely with business owners and management teams on financial reporting and analysis, cash flow, budgeting and forecasting, accounting oversight, tax strategy, and broader financial decision-making.
