  • Silverpelican
    Andrew and Mike were amazing. Very professional. I can not say enough to convey how knowledgeable and thorough Andrew is. Almost line by line, he explained my return. I was worried I was going to owe the IRS but ended up getting a refund. Andrew listened to my situation and asked questions to get me every credit possible. He gave me great tax advice for the upcoming tax year as well. Truly a great experience and, without hesitation, I recommend Paramount and Andrew for all your tax and accounting needs. Thanks
