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.

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.

Very Nice Law Firm

I hired Cynthia to represent me in 2010. I fell on ice at work and tore my rotator cuff all the way through. I was tired of dealing with the insurance company claims adjuster. She just wasn’t that nice, she never returned my calls, kept delaying things. It was so nice to just hand the whole mess t...o Cynthia. She met with me personally, spent a long time getting to know me, and worked my case quickly and professionally. She and her staff are just plain nice to work with, always friendly, easy to talk to, and I always felt comfortable asking questions, and talking to them. We just settled this week, and I am very happy with the settlement. In fact, it is quite a bit more than I ever expected. I would hire Cynthia again.

Highly recommend for brain injury

My husband worked for a very large company, (I can’t say who) that delivers packages worldwide. He fell off a loading dock 2 years ago, onto his back and head. He suffered an injury to his head and brain and has never returned to work and will never return to work. He has never been the same since.... He is depressed, has terrible memory problems, can’t concentrate, his mood has changed terribly. He is nothing like the man I married. Anyway, Cynthia Hennessey was our lawyer for the workmens comp case. Thank goodness we found her. As a nurse, she knew everything there was to know about head injuries. The workmens comp doctors all said there was nothing wrong with him, that he was faking. Cynthia believed him, and knew exactly what we were going through. She sent us to experts who finally did the correct testing, and took our case to trial. The judge was visibly upset with workmens Comp. He gave us everything we asked for, lifetime benefits, medical treatment and attendant care and all of our bills paid for. Again, thank goodness for Cynthia. I strongly recommend her for any type of brain injury or head injury.

Very Good experience

My husband had a fall at work injuring his neck and back. We knew it was a serious injury, and that we better get a lawyer to represent us. We had no idea where to turn. I opened up the paper and saw an advertisement for Cynthia Hennessey’s Workers Comp 101 the workshop. We cleared our calendar and... went. I can only say we left absolutely amazed and sure that Cynthia Hennessey was going to be our lawyer. She is a nurse and a workers comp specialist. In 2 hours she taught us more than I ever believed I could learn about Work Comp insurance companies, the Second Injury Fund, Social Security, future medical treatment etc. She was funny, smart and informative. Our case is still pending as my husband has just had his 3rd surgery. But I couldn’t be happier with our choice of lawyer. I highly recommend her.
