I have been a client of Barbara Barschak at Katz Cassidy since 1992. She is top notch in experience, expertise, and figuring out just how to save you the most money yet conservative enough to keep you from getting audited. She is one of the most conscientious people I know, endeavoring to serve her clients to the utmost of her ability every moment. There is no one I trust more than Barbara. She really cares about her clients, and she's fun and upbeat, too. What a pleasure!

I have been a client of Katz Cassidy for nearly 20 years now. Richard Cassidy is thorough, reliable and immensely helpful. He always quickly and competently responds to my questions. I would recommend this firm to anyone. They're the best!

My sister has used this firm tor her taxes for several years. She works with Barbara Barschak who is quite pleasant. They are very consistent. Every year there are errors. Of course my sister is only aware of the ones that she catches. This last year the IRS found that social security income had been omitted and levied a fine for underpayment of taxes. Unless you enjoy spending hours checking up on your accountant you may wish to select a more reliable firm.
