Kate’s areas of expertise includes providing exceptional client service to both individuals and entities in a variety of industries including real estate, retail and consumer products, healthcare, and professional services. In addition to serving clients, Kate also sits on multiple committees within the Firm working to evolve and assist the firm in a variety of ways including improving client service and staff retention.

Kate was born and raised in Kansas, and relocated to Orange County during high school. She met her husband, who is also a CPA, during a Scuba diving class.
