Much like you don't wait to join a gym until you're healthy, you shouldn't wait to work with a financial planner until you're wealthy. Unfortunately, the financial industry historically only wants to work with clients who have <insert any seven-digit-minimum amount of assets>. The good news is there are now plenty of financial planners who will gladly work with clients regardless of how much they have already saved. I am one of those planners. ;) I've been a financial planner for over a decade now, and I've worked lots of different clients from all walks of life. I've come to learn that sticking to the basics and keeping things simple is the best approach when helping clients develop a financial plan. My role is to help guide you on your path to financial freedom. New clients start with a financial plan. This is where we talk about your goals, time horizon, and all the numbers. We’ll review different scenarios so you can see what’s possible. By the end of the initial plan, you should be up and running, moving in the general direction of your goals. In six months (or sooner, if you prefer), we’ll meet to review how things are going and make any needed adjustments. From there on, we’ll talk about any future meetings that may be beneficial.

I specialize in growing families that work in the medical and technology industries. My wife has worked as a physician since 2013, so I'm familiar with the challenges that those in the industry face. Geographically, we are located in the Bay Area, so my practice has naturally become split between medical professionals as well as those working at tech companies, with a significant portion coming from Google.
