  • Testimonials

“I have been a client of Brendan Hennessy for over 4 years. I was fortunate to meet him while he was working with another law firm. I followed him to the start of his private practice because he was compassionate, responsive, and sincere. I was extremely stressed due to the years of unlawful treatment by my employer. Brendan consistently responded quickly to my concerns with great advice that reassured and calmed me. He is a diligent, intelligent, and tenacious attorney. As promised, he remained on top of the case from beginning to end. When the time came for a settlement conference, he demonstrated that he is a fierce advocate for his client. Brendan was very effective when interacting with the judge and my employer’s attorney as evidenced by the outstanding results he secured for me. Brendan Hennessy is trustworthy, knowledgeable and, in my opinion, the “Go-To” attorney for employment law cases.” -Rosemary.

“… Brendan listened to what I wanted and followed through.  He resolved my problem.  I would highly recommend him.”  -R.N.E.
