She studied advanced tax law by taking several courses through Boston University's LLM program. She currently serves as an estate planning consultant for Bessemer Trust Company in addition to running her own law firm.


Rosie spent several years working in Silicon Valley at a prestigious law firm serving ultra high net worth clients, including Founders, Directors, and Officers at companies such as Google, Netflix, Juniper Networks, Tesla, DocuSign, Looker, Nvidia, Xilinx, and Fortinet. Rosie spent time practicing in Honolulu, Hawaii serving ultra high net worth clients, including descendants of Hawaiian royalty. While in Orange County, Rosie assisted many high net worth clients of notable fame in the entertainment industry and the manufacturing industry. Rosie started her own law firm to provide a more customized and personal service to clients than what is offered through larger law firms. Trust is essential to building client relationships, and with her own law firm Rosie is able to provide more attention and care to each client matter.
