  • "Anthony is very professional and very knowledgeable regarding my business tax matters.
    I don't see Anthony as my accountant but as a friend; he give me advise regarding my tax
    concerns like you talk to your friend and seeking solutions. I'm very happy with his service
    and I recommend him to everyone"

    - Sean H.
  • "Anthony Ontko has been my CPA/Accountant for several years now and I couldn't be happier.
    He makes sure all my forms are filed on time and looks for all possible ways for me to lessen my
    tax liability. He is always willing to take the time to explain things to me and answer my questions.
    On those rare occasions when i ask him a question he doesn't know the answer to immediately,
    he takes the time to research the subject and gets back to me in a timely fashion.

    Taxes are never fun but since Anthony has been my CPA, the process is more than bearable!
    I would highly recommend you consider Anthony Ontko for all of your accounting and tax needs."

    - Allan P.
  • "I can tell you I've been with many CPA's throughout my career as a realtor and I've been
    the most satisfied with how Anthony has handled my taxes. He understands the real estate
    side of things very clearly when it comes to taxes"

    - Nancy H.
  • "Anthony, I wanted to take a minute to personally thank you. Your expertise in
    helping guide and influence major decisions we made in fiscal 2015 not only set
    us apart from our competition it enabled us to increase revenue by 19%. I look
    forward to a long and prosperous relationship with Ontko, LLC"

    - Ken T.
  • "Anthony has been not only a diligent CPA, what is fully expected, but also very
    thoughtful advisor and partner. It is particularly important because frequently
    business undertakings and solutions have indirect repercussions which are
    quickly visible to a skilled CPA, and Anthony always volunteers a wise advise.
    That makes him a treasured colleague, not just an accountant"

    - Yakov S
