Peter Pastman, CFP®

Managing Director

Peter founded Keystone Financial Planning in 2023 after spending the previous 15 years affiliated with Raymond James. Peter earned the CERTIFIED FINANCIAL PLANNER ™ certification in 2011, and his passion for financial planning has been invaluable while working with clients through all types of markets during his time in the financial service industry.   

Peter appreciates the opportunity to help his clients establish the foundation for their financial plan. Peter has seen first-hand the benefits of having a solid financial plan in place to help navigate the up and down markets. The most rewarding part of this career is seeing clients achieve the goals they’ve worked towards over the years. Whether it’s providing gifts to their kids, helping pay for a grandchild’s education, or making a major donation to a beloved charity. It’s rewarding to simplify complex financial planning strategies, so our clients can have a level of comfort with their financial plans even during turbulent markets.  

Peter previously served on the Board of Directors for Bon Secours (a senior care facility), Board of Directors for Preserve the 'Burg, and a Committee Member of St. Anthony's Hospital Foundation. Peter is currently involved with 100 Good Guys - St. Pete. Peter enjoys playing tennis at St. Petersburg Country Club and the Racquet Club of St. Petersburg and spending time with his family. Peter's wife, Sara, is a native of Saint Petersburg, and they have two beautiful children, Will (7) and Amelia (5). Peter graduated from the University of Florida with a degree in Economics, and he continues to cheer for his alma mater.
