Diana Stadelnikas

Title: Trial Attorney
Office: Sarasota, FL

Diana L. Stadelnikas, Esq. represents clients and families across the nation who have been injured by adverse vaccine reactions. She is admitted to the practice of law in Florida and is a member of the United States Court of Federal Claims bar in Washington, DC. Ms. Stadelnikas became a partner at mctlaw in 2009.

Ms. Stadelnikas is a graduate of West Virginia University, first earning a Bachelor of Science in Nursing in 1984. She was selected to be a Sigma Theta Tau Honor Society of Nursing member. Diana went on to work at the WVU Medical Center as part of the pioneer team of nurses to help open the first pediatric critical care unit. 

Although she enjoyed nursing, loved individual patient care, and helped families, law school was always a personal goal for her. “I don’t feel like I can change the world, but for each client, I like to use the law to change it for that one person. What I find most gratifying is what is it about the law and what I know, and what I can do to make it better for this family or client to make a difference in their life.”

My experience with mctlaw for my hip claim was remarkable, I found the communication to be outstanding. I also felt they did an excellent job setting expectations and then delivering on those stated expectations. From net amount, timing of the settlement, how much each related party would receive etc. they were outstanding. I would highly recommend them. They are very professional and set the bar in vaccine injury practice.


Five stars for mctlaw! Paralegal Leslie Williams did an outstanding job communicating with us and keeping us informed. Thanks for all the help.


I am excited to be receiving my final payment so I can put all this behind me. I am really grateful to everyone who played a part in getting me this well deserved settlement as my life has been negatively impacted over the years.


We cannot thank you enough for the services your firm has provided for Marie and I in our time of need. I could not have chosen a finer firm near or far to represent us.

My first response is “Wow!” It has only been 11 months since I first heard of “SIRVA” and an HHS program that awarded compensation to its victims and only 7 months since MC&T accepted my case. I feel that your efforts on my part made all the difference.
