Brenda S. Kangas

CPA at Business & Tax Accountants, LLC

For me, it's all about working closely with small business owners to help them keep financial control of their company, and more importantly help them grow their business through consulting and tax planning.  Working with individual clients during tax season is gratifying especially when I can help them achieve their short term and long term goals. At BTA we are big enough to have the resources to help our clients achieve success, but a small enough office to care about our clients.
