Expert Guidance Through a Complex Workers’ Comp Case

Cynthia Hennessey provided exceptional representation during one of the most difficult periods of my life. Her knowledge and experience in workers’ compensation law were evident from our first conversation. My case was medically and legally complex, yet she navigated every detail with confidence, pre...cision, and strategic insight. Throughout the process, Cynthia ensured I understood what to expect and consistently advocated for my best interests. She anticipated challenges, addressed obstacles proactively, and handled negotiations with strength and professionalism. Her depth of experience in workers’ compensation made an overwhelming system feel manageable and allowed me to focus on healing. She was particularly effective in addressing delays, denials, and administrative barriers that often arise in complex claims. Her persistence and ability to keep the process moving forward made a tremendous difference in both my care and my peace of mind. What truly sets Cynthia apart is her compassion. She recognized the emotional and physical toll this journey took and treated me with dignity, patience, and genuine care. I never felt like just another case — I felt heard, respected, and protected. Because of Cynthia’s dedication, perseverance, and expertise, I am able to move forward with peace of mind and security for the future. I am deeply grateful for her guidance and would recommend her without hesitation to anyone seeking a workers’ compensation attorney who combines exceptional legal skill with true compassion for her clients.

Accomplished and Caring Attorney

Cynthia Hennessey successfully represented me “long distance” with a workmen’s compensation claim several years ago after I suffered a traumatic brain injury from a fall while at work. I give her my highest recommendation. She is a caring, knowledgeable, accomplished and very successful attorney. ...Although we never met in person, she always made time for calls when needed despite her very busy schedule.

Very Good Experience-Highly Recommend

I hired Cynthia Hennessey after firing my previous lawyer. after dealing with one of the "TV law firms" for a year who never returned my calls, I was so happy to find a lawyer who is so kind and compassionate. The girls who work for her are personal and nice too. They always talked to me and explaine...d the process. Cynthia went to court twice to get them to pay my weekly workman comp checks. At the end she fought to get me a very nice settlement. I highly recommend Cynthia Hennessey law firm.

Totally Recommend

I hurt my back at work. Workmens Comp sent me to a hired gun doctor who didn’t spend 5 minutes with me, and said that my back wasn’t hurt and I didn’t need any treatment. I was referred to Cynthia Hennessey by 2 guys at my work who she represented. They spoke very highly of her. (Honestly, I called ...another lawyer first-and he wouldn’t give me the time of day). I called Cynthia’s office, and I knew right away that I made the right choice. Not only is she a lawyer but she is also a registered nurse. She knows more about medicine than the idiot doctors that workmens comp sent me to. She personally took my case, and fought very hard to get me into a better doctor, and it turned out I had 3 herniated discs in my back and had to have surgery. I was off work for 7 months. Cynthia got me all of my benefits, and a very good settlement at the end. I am so happy I did not try to do this on my own or go to the first bozo lawyer I called. I highly recommend Cynthia Hennessey.
