About Us ...is really all about you

A Five-Decade Commitment to Learning What’s Important

Perhaps the most important thing to know about us is that we have invested significant time over the past 50 years in learning about you – the growth oriented entrepreneur and small business owner. Here are some of the more important things we’ve learned:

  • You are not really all that interested in certified public accounting …but you do value trusted advisors who help your business operate successfully.
  • You have a keen focus on business growth…and need to “off load” recurring, but important, business tasks in order to address your scarcest resource – your own time.
  • You recognize that you can’t do it all…and appreciate the considerable value that a long-term business relationship with a few trusted advisors can provide for you. 

  • You have a real mastery of your core business…but you need savvy professionals to help with other essential aspects of your operation.
  • You value business insights…especially those that help you capitalize on unforeseen opportunities and efficiencies.

  • You frequently have complex tax challenges…and want to hand those problems to someone who knows your business and who “has your back”.

Our Insight Drives Valuable Results

If you find yourself and your business situation reflected in this profile, we may be the right resource for you. Be prepared for our avid interest in learning about your business – we are noted for our business curiosity and the insight that results from it. Our insight has driven us to achieve the best possible situation: we are enjoying the growth and success of our own business by helping our clients achieve those same goals in theirs.
