  • Lisa Antoinette Hayes

    I have known Duncan Manville for over a decade, and during that time have worked with him as co-counsel, consulted with him, and tried cases and appeals together. He is a phenomenal lawyer, gifted advocate, and tireless champion for his clients. From my somewhat unique vantage point, I have observed his skill, persistence, and expertise used to successfully resolve complex and difficult matters for his clients. Moreover, he is a wonderful person whose contributions go far beyond the law, and the Seattle community is a better place as a result of his time and effort. If I am ever in a position where I need to hire counsel, Duncan will be my first call.
