ERISA denial lawyer

Michael B. Horrow, Founder

Client with an ERISA or LTD Insurance Denial?


Our Specialty is Your Referral.



    I would definitely recommend people to your firm. Michael is very straightforward and laid out relevant information for me to know and also hypothetical scenarios to keep in consideration. He was also very good at answering my questions about possibly what the other side was thinking and if he didn’t know an answer to my question he would tell me. The honesty was much appreciated. Also, communication was very timely and it was easy to get in touch with him if I needed him as well as with yourself and the office staff. I also liked Michael helping me with use of language when filling out paperwork. I like to understand what it is I’m involving myself with so that I can take an active role in my case and he helped me do that.

    I want to thank you for the excellent job you performed navigating through the gauntlet of insurance company red tape.

    Mr. Horrow has proved to be excellent… He kept us informed throughout the long process and was successful on every issue. I wish every experience I have had with the legal profession was as pleasant and satisfactory as this one.

    Donahue and Horrow, LLP came to me highly recommended, and they did not disappoint. The attorneys of this firm are not just amazing at what they do; they are kind and compassionate people. Through a difficult and delicate situation they always went above and beyond to make sure I felt comfortable and at ease. I always felt that they had my best interest at heart. I cannot thank them enough for all that they have done for me.
