William R Koscinski Jr. CPA

This place is nothing short of phenomenal! Excellent professional services at reasonable prices. That's a great model for unlimited success.

Absolutely a pleasure working with Bill Koscinski. He will help in any situation. Quick return on finishing your taxes. Everything is spelled out in black and white. No hassles, no headaches. Turn in your paperwork to the office and "Voila! ". Your taxes are completed! Reasonably priced also.

It's okay if you want your taxes done etc. I didn't really care for the demeanor of the secretary. My relative has been going here for quite some time. I spend half my time in the US, I only work part time when in the US, and my stuff is easy to do. I just think they're a bit pricey for the simplicity of my taxes.

I guess I am just used to living in Singapore, where people are so much different, less rude.

Amazing place with such a strong work ethic. They get the job done on time and saved us a lot of money!

Professional, accurate and always helpful in answering any questions or concerns on taxes, whether filing personally or for a business.

Bill is great. But Kim is nasty and unprofessional. She is short with you and annoyed if you ask questions. It’s their job and they are providing a service. She is nasty and rude.

I have been taking my taxes to them for over 5 years now and they are always professional, helpful, and work in a timely manner. They also do their best to provide the best tax advice for our family. I will continue to work with them in the future.

They do our taxes every year and are always quick, responsive, and thorough. They send out a handy checklist every year and we keep it in a folder and add documents to it throughout the year so when it's time to file, everything is already together and we don't have to try to figure out what we need.

Best accountants in the valley! Very thorough, easy to work with and answer every question, they make sure you have everything in order, the secretaries are the greatest, very helpful. I recommend this company to everyone I know.

We have been working with Bill for about 2 years now. He does our taxes plus payroll and we highly recommend his services.both he and his staff are friendly and knowledgeable.

I feel that Bill Koscinski and team are experts in helping me to better run my business. I highly recommend them for all accounting needs.
Bill is both friendly and patient and I enjoy working with him.

I cannot recommend this firm enough! As a young person who is relatively new to doing my own taxes, they were incredibly helpful and organized, giving very clear directions on what and how to submit everything to them. I will absolutely be working with William R Koscinski Jr.again and moving forward!

Been using Bill and team as my accountant for about 5 years. He helped me transition to my consulting business. They are helpful, professional, and fair. Would highly recommend using his services.

Had a few questions about forming/ starting my own business. Not only was everyone who I talked to over the phone incredibly nice, but very informative. Highly recommend to anyone seeking accounting advice.
