Absolutely AMAZING!!! I am in my 20s and a 1st time business owner. Being able to go to William with any questions is the best! He is beyond wise, truly a gem in the industry. Quick and effective. Saving time on fees! I never write google reviews… Paramount Tax PSL deserves so much more recognition than my words or review can help give them!!! THANK YOU FOR MAKING MY 1st YEAR IN BUSINESS A SUCCESS! ⭐️⭐️⭐️⭐️⭐️
I had many questions and the staff (Mathew and Will) were very knowledgeable about the subject and went above and beyond in wandering my questions and concerns. They were very honest and I never felt like I was being steered on the wrong direction. I generally prefer to support local establishments but these guys are the exception. If you’re looking for experts regarding your taxes, business etc then this establishment is where you should go.
My first in person meeting with William was great. He and I had spoken over the phone several times about different things and he is always willing to share information and work with his clients. Great experience and will definitely be sharing his information with anyone who has a need.
We had the pleasure of working with William. He is extremely knowledgeable and educated us on everything we were missing. We have a new baby and we were able to meet with him in the comfort of our own home. All these years wasted going to H&R. William was able to save us a significant amount of money! Happy to have found our new go to tax guy! We will be recommending this company to our family and friends.
