“I have been going here for two years now and I am very pleased with not only the efficiency of getting my taxes back but the above and beyond customer service Josephine does for her customers. This is a family owned business and I support it 100 percent. Her genuine care and compassion shines through her and her business. They are very helpful and if you need assistance in Spanish please call them! I know it is very difficult to deal with paperwork and to trust. With Stanza you will definitely be reassured you will be in good hands. Thank you!”

“Excellent tax preparation service. Ms. Josephine took wonderful care of me; she is extremely kind and professional. What I appreciate most is that she was always willing to patiently address all my questions. Plus, she speaks both Spanish and English fluently, which makes the whole process so much easier. Highly recommended! I will definitely be back next year!”
