I'm a CPA with two offices: Illinois and Hawaii. I travel to meet clients at both offices. I'm also a member of Rotary International, or Rotary as it is often referred to. We operate our business following the 4 way test of Rotary and expect our clients to do likewise: 1. Is it the truth? 2. Is it fair to all concerned? 3. Will it build goodwill and better friendships? 4. Will it be beneficial to all concerned? I've been a CPA since 1980 and have prepared tax returns and represented clients since 1975 while still in college. I've found over the years that following the Rotary 4 way test to be helpful when assessing which is the best option for my client and myself. If you, potential client, see yourself understanding and accepting the 4 way test for conducting your business, then please give me a call or send me an email. If on the other hand the 4 way test doesn't work for you then please move on to the next preparer listing because most likely we won't be a good fit for each other.

q & a

What characteristics do your favorite clients share?

Honesty, willingness to provide timely answers to our questions and public volunteerism. Paying it forward as a way of life.

Why should a client hire you?

Because I am excellent at ensuring the best tax return preparation with minimal client angst about the process.

What single project or task would you consider your most significant accomplishment in your career to date?

My family and their adult successes. Without my family's support I doubt I would be as successful or content as I am today.
