I am committed to understanding my clients’ business and their goals, and implementing a strategy to achieve those goals is my focus and core strength as a lawyer. As the former CFO and general counsel of a family-owned business, my mindset is to embrace each client’s business as if it were my own. Whether negotiating before a regulatory agency, obtaining permitting for complex projects or developing alternative energy project solutions, I strive to consistently achieve favorable outcomes that align with my client’s best interests.
