Bookkeeping & Tax for Small Businesses
Steven Rutherford CPA

After interviewing several firms and practitioners, I decided to affiliate with CPA Tax Accountants SDO CPA. Their team grew their tax & accounting knowledge at KPMG, multiple family offices, and Tax Management experience with EY LLP in Dallas, Texas. They bring a wealth of tax and accounting knowledge.
