Kathy spearheads daily operations throughout the firm, including contracts, invoicing, accounts payable, accounts receivable, financials, payroll, and human resources. She has a compassionate spirit and deep understanding of the complexities of the business, with a keen ability to show our team how everything fits together. Her detail-oriented business approach provides the foundation for O’Brien administration and client relations, and allows the architecture team to focus on more creative aspects of our work.
