Prior to entering private practice, she gained experience representing plaintiffs in personal injury matters, served as a Legal Intern with Widener University’s Veterans Law Clinic assisting disabled veterans with benefits claims, and completed a legal externship with the legal department of a large Philadelphia-area hospital and healthcare system. This diverse background provides Nikki with a well-rounded perspective that enhances her ability to evaluate claims, anticipate opposing strategies, and effectively advocate for her clients.
