What People Say About Us

I’m pleased with the services provided but most importantly, the concern and attention given to a challenging situation we encountered. Thanks, Coop and Valerie!!

This is the 2nd straight year that my wife and I have done our taxes with this very fine company in Long Beach. We both had some anxiety about taxes as we had recently purchased a house. Steven Cooper and his very helpful and knowledgeable staff really took us under their wing, made us feel at home and were professional in every way – explaining complex tax laws in a way we could understand. Mr. Cooper also guided me personally through the nuances of what it takes to have a business on the side. We could not be happy enough with the exquisite attention to tax detail, all the time displaying a real down to earth touch simultaneously. Take your tax business here right now, you will not be disappointed! Highly recommended, and did I mention they were really good people too?

I found Cooper through yelp and he is as great as they say. Very helpful, lots of useful information. He was able to help me and my husband work out our situation with our taxes and even helped me get back money from the previous year that my old tax lady said i didnt qualify for. Hes very personable and friendly – a jokster and makes you feel very comfortable. Easy to reach and talk to with any questions or concerns. Highly recommend!
