About Me
Hi, I’m Brian H McKinstry Jr, founder of McKinstry Bookkeeping, a live-human certified QuickBooks ProAdvisor bookkeeping firm based in Laguna Hills, CA. By harnessing modern cloud technology, I deliver executive-level financial architecture and forward-looking insight to business owners nationwide.
I mastered the transition from manual, disorganized records to the power of the QuickBooks Online ecosystem. By replacing fragmented workflows with sophisticated financial architecture, I specialize in identifying hidden margin leakages and engineering the strategic tax savings that traditional bookkeeping often misses. Today, my focus is on delivering the clarity and foresight my clients need to secure their profit and scale with absolute confidence.
A California native, I spent my younger years surfing and my recent years fishing in San Clemente and Dana Point. Today, I live in Laguna Hills with my two teenage sons.
