ABOUT CORNERSTONE LAW FIRM

Since its inception, Cornerstone Law Firm has established itself as a go-to in the legal community. Through diligence, work ethic and implementation of processes that refine and streamline the client experience, the firm has set the bar high. Primarily focused on litigation, Jason O’Neal has forged relationships with transactional attorneys who practice in similar disciplines.

 Over the years with her prior firm, Sarah Geltz had numerous opportunities to work with Mr. O’Neal as he navigated complex issues for some of her clients and as a result the two saw the opportunity for synergies within their practices.

Both attorneys have ties in their local market and felt that together they could offer a truly client focused experience, whether they were proactively creating structure for individuals and businesses, or when needed, addressing issues that necessitate dispute resolution.

In late 2022, the pair launched their collaboration with the goal of better serving their clients, augmenting their existing practices and developing deep roots within the firm and community. With complimentary styles and dedication to the clients they serve, the pair hope to make a lasting impact in their practice and develop a truly innovative firm with lasting relationships with the clients they serve.
