“ As a lawyer specializing in sexual assault and abuse cases, I work very hard to earn my client’s trust. Legal proceedings are often difficulty to navigate, and pursuing justice can be an extremely emotional process for a survivor. I’m passionate about fighting for my clients, and helping them understand and pursue all of their legal options. ”
