Raising A Voice: Attorneys With Experience And A Focus On Results To Help

Even if you are not sure whether you need legal help, we believe it is in your best interests to discuss your case with an experienced workers’ lawyer. The decisions you make in the days and weeks following an injury can affect your life and your health for years to come.

Our personal injury practice is led by firm owner Attorney Christopher Marzzacco, who has been listed in “The Best Lawyers in America” every year since 2017 and named in “Super Lawyers” every years since 2017. In addition to giving lectures and writing books on a variety of topics in personal injury law, Mr. Marzzacco has secured several awards in the millions of dollars on behalf of injured clients.

Historically, our founding attorney, Katherine L. Niven, was a former workers’ compensation law judge who presided over thousands of hearings. As a result, she knew what judges look for when they rule on a case in a hearing or an appeal. When she practiced with the firm, Ms. Niven was a strong advocate for injured workers. Before she became a judge, she served as chief counsel for the Pennsylvania Bureau of Workers’ Compensation. In this position, she enforced workers’ compensation laws and brought criminal actions against companies that failed to carry workers’ compensation insurance.

Our current Worker’s Compensation Division is overseen by Attorneys Adam Crosier and Jesse Rhodeside. Adam Crosier is a Certified Worker’s Compensation Specialist by the Pennsylvania Bar Association Section of Workers’ Compensation Law. Jesse Rhodeside, an accomplished advocate for injured workers, handles complex cases for the firm as well. These two senior litigators supervise a capable group of associate attorneys who litigate on behalf of injured workers every day.

Attorneys Michelle Rhizor and Thomas Meister bring more than 50 years of combined experience to our Social Security Disability practice. Both have focused on Social Security and workers’ compensation for much of their legal careers and bring seasoned insight to each case. Attorney Nicole Ridley came to our firm with unique experience from her pro bono work helping Social Security claimants in the community. We are proud of our firm’s record of success securing adequate compensation for injured and disabled clients.
