Hello! I’m Guy-Robert Porter. I started LifeStream Family Offices in order to serve clients at a higher level.

Let's create a team dedicated to protecting what's important to you.

Here are a few things that you should know about the work we do at LifeStream Family Advisory:

  • We appreciate that you are an individual.

    We get to know you personally as well as your business or home environment. We listen to you: what’s important, what your priorities are, what challenges you are facing and how you view your strengths. Our goal is to work with you to implement strategies that would best serve you, our client.

  • Our programs and strategies are flexible.

    Different clients need different things at different times. Our programs and strategies have built-in flexibility to ensure maximum relevance and ‘do- ability’ for our clients. We design action plans that may produce sustainable results with less struggle.

  • We operate with the highest level of integrity.

    We are always open and honest with our clients – we tell it like we see it. If something is not working, we won’t kid ourselves or you that things are okay. We don’t believe in wasting your valuable time – or ours – on strategies that aren’t getting you measurable results.

A website isn’t a sufficient medium for making your decision. Let’s have a strategy session.

  • Virtual Meetings with Zoom

    Share screens, documents and even point at things… the Zoom app allows us to have a great conversation and record it for future use. You can download the Zoom app at www.Zoom.us. The free version works fine. If you don’t want to download the app, there will be a call in number for you to use. I will still be able to share my screen, if I need to, and record the work for further use.

  • Would you like the Gift of Clarity?

    Let’s talk on the phone for a bit. Get to know each other. Then let’s sit down at my office for our unique LifeSource Conversation. If you and your spouse participate fully in this one hour process, I promise that you will leave with a greater sense of purpose and clarity about what you want out of your money and your life. Whether or not you work with LifeStream®, you’ll have a valuable tool to make smarter choices about money.

  • Want to know more about me?

    Connect with me on LinkedIn. I’m a member of several professional groups and I have a few presentations that will be released there soon. Take a look at my background. I have one of the more eclectic resumes in finance.

Phone: 314-565-4910

Best time to call is after 4pm, Monday through Thursday.
