My specialty

With over two decades of public accounting experience, I specialize in corporate and individual income tax planning and consulting. My strong communication skills and ability to listen generously enable me to fully understand clients’ needs and think about what’s next to provide proactive solutions. From selecting the right entity structure for new businesses to leveraging R&D tax credits to enhance profitability and fund innovation, I enjoy educating clients about tax opportunities that can drive growth. When I am not serving clients, I am educating and mentoring staff members or networking with technology professionals, VC firms and Private Equity investors. I am always happy to make introductions.
