Moonshot Planning LLC

Hi, I'm Louis Guajardo. I’m the founder of Moonshot Planning, a financial planning firm built specifically for creators, freelancers, and self-employed professionals - the people traditional finance tends to overlook. My journey started when I saw firsthand how the industry dismissed talented creators who didn’t fit the usual model. I watched a young creator making more than many people twice her age, yet she had no retirement plan, no tax strategy, and no financial roadmap. When I asked how we could help her, I was told to just ignore her. That stuck with me. After passing my CFP® exam and launching my own firm, Brighter Days Planning, I realized I’d built something safe and predictable - like everyone else. But when that same creator came back, signed up, and started referring her friends after we built her plan, everything changed. I realized this wasn’t just a niche; this was the entire point. So I burned it down and rebuilt, and that’s how Moonshot Planning was born. Today, I’m committed to serving the creators, freelancers, and self-employed people that the rest of the industry has overlooked, helping them build personalized financial plans that actually fit their lives and careers. Outside of work, I stay active and creative. I train in jiu-jitsu and boxing, skateboard, draw, and listen to music, all of which help me stay balanced, focused, and energized both personally and professionally.

Chatterton & Associates

Before we ever talk about financial planning, my team and I want to genuinely understand and deeply care about your life. Not just your accounts, taxes, or investments, but what those things are meant to protect. Your family.
 Your business.
 Your future.
 Your peace of mind.
 The people who depend on you. Our most important responsibility as a team is to listen, understand what matters most, and deeply care about your situation, because it truly matters. Once we fully understand what you are carrying, what you are trying to protect, and what you want your money to make possible, we then help turn that understanding into a clear plan. As a CERTIFIED FINANCIAL PLANNER® at Chatterton & Associates, my goal is simple, to give business owners and retirees a clear plan that keeps you one step ahead so you pay as little taxes as you legally have to, avoid costly mistakes, and are covered if something unexpected comes up. At our firm, wealth, tax, and estate all work together under one roof. I work directly with our CPAs, EAs, and attorneys to help keep your plan aligned and save you money. Qualified wealth clients also receive tax service credits through our firm, which often cover most or all of their tax services. I focus on making financial planning clear and easy to follow. I help clients understand their investments, reduce taxes owed, improve cash flow, and prepare for major transitions like retirement or selling a business. As a CFP® professional, I put my clients’ interests first. I take time to understand your goals and build tailored plans you can act on. I help my clients stay clear on where they stand, what to do next, and why it matters so they can move forward with confidence.

OSAIC

Prab Marwah spent a decade in startup growth marketing before becoming a financial advisor — which means he has strong opinions about burn and churn rates, a soft spot for founders, and a firsthand understanding of what it's like to be great at your job and still feel completely lost when it comes to your money. He works at RYSE Financial, a firm his mother Opinder founded in Southern California. It's a small, relationship-first practice that works with high earners in tech and healthcare, business owners, and solopreneurs — people with real income, real complexity, and not nearly enough hours in the day to figure out what to actually do with it. He takes the work seriously. Himself, a little less so. Outside the office, you'll find him deep in a golf round he definitely could've played better, rewatching an anime he's already seen twice, or rekindling his love for music and DJing. He's based in Los Angeles and works with clients both virtually and in-person. Securities and investment advisory services offered through Osaic Wealth, Inc., member FINRA/SIPC.
