Rosanne Costello

Financial Advisors

Rosanne Costello is a wealth management financial advisor based in San Ramon, CA.

Rosanne became part of CAPTRUST in 2019 when Watermark Asset Management joined CAPTRUST. She serves as a senior vice president and financial advisor responsible for providing investment advisory services and comprehensive wealth management services to high-net-worth individuals and families. Her philosophy includes an investment and wealth planning approach that emphasizes the long-term view. Her most satisfying client interactions are when, after helping improve an individual’s financial outlook, she’s able to help them understand the how and why of it. 

Prior to joining Watermark in 2014, she served at Charles Schwab for 24 years where she consistently ranked among the top five percent in her peer group. When she’s not in the office or with a client, Rosanne loves taking adventures with her family, reading, cooking, hiking, and walking her dogs.
