Dave and Debbie helped me when I started my first construction company. They have always kept us on the up and up with our financials, and I don’t know what I would have done without them. My business partner has worked with them for over 10 years and I’m happy to recommend them as a current employee. Thank you, OSA.

Dave has helped us tremendously with both of our businesses. He keeps us organized and provides accurate and current information regarding tax laws. We sleep well knowing we are filing and paying our various taxes properly. David has been flexible and has accommodated us when we have had staffing and bookkeeping hiccups. He's an absolute joy to work with and we don't know what we would do without him.

I have used Dave's accounting services for 15 years. He is knowledgeable, professional, and a pleasure to work with. He handles all aspects of my payroll, my tax payments, and P&L's for my restaurant. I don't know what I would do without him. He is always available for my questions. I would highly recommend him.

It is a pleasure working with Dave. He did a thorough review of my taxes and got it done on time. I highly recommend his services.

Karen, Thank you for your review of my services! We have developed an organized process over the years to gather and organize your deductible business expenses for your self-employment and other individual items, which has made the tax preparation and filing as "painless" as possible. Thank you for your attention to the process, I look forward to working with you again next year. Dave
