Testimonials
Rave reviews from companies like yours.
simply awesome
I was referred to Bay Business Group in 2010 after another CPA made (very costly) mistakes on my 2008 and 2009 Federal and State Returns. Mary Leighty (CPA) has done my taxes since 2010 and I could not be more satisfied. Her work is simply awesome and her communication skills and responsiveness have taken all the stress out of tax preparation season. Thanks Mary!!!
