Griffin D Nienberg

I founded Innermost™ Wealth Management to create a more personal, thoughtful approach to financial planning and wealth management. My background in both finance and psychology shaped my belief that money is not just about numbers. It is deeply personal and connected to your values, goals, and life experiences. I work with professionals who want to grow and simplify their wealth, with a special focus on women navigating career growth, equity compensation, and major life transitions such as divorce. Many of my clients are balancing busy lives and complex financial decisions, and they value having a long-term financial partner who truly understands their needs. My firm is centered on ongoing wealth management through investment advisory relationships. Clients work with me for comprehensive financial planning and investment management that evolves with them over time. As a CERTIFIED FINANCIAL PLANNER® Professional, Chartered Retirement Planning Counselor℠, and Certified Divorce Financial Analyst® Candidate, I provide technical expertise and strategic guidance, while also recognizing the emotional side of financial decisions. My approach is compassionate, judgment-free, and designed to reduce stress while helping you feel more confident in your choices. I operate a fully virtual firm, working with clients across the country who appreciate flexibility and convenience. My goal is to simplify your financial life, provide clear advice, and help you align your wealth with what matters most to you. Outside of work, I enjoy traveling, photography, cooking, and spending quality time with my Beagle, Gracie.

You make good money. You have a plan somewhere. What you are not sure about is whether anyone is actually watching the whole thing. Right now, you probably have an advisor for investments, a CPA for taxes, and maybe an attorney for estate documents. None of them talk to each other. You are the one in the middle, repeating your situation to three people who each see one slice of it. I build the financial plan, and I prepare and file your tax return myself. Same person, same conversation. The tax decision and the planning decision get made together, by someone who can see how one moves the other. Most advisors hand you off to a CPA who has never seen your plan. I do not hand you off. I work with dual-income parents, director level and up, two demanding careers, kids at home, and a financial life that has gotten more complicated than you have time for. Equity comp you have not fully sorted out. College creeping up. Estate documents written before your last job change. All of it in motion at once, and no one holding it together. What I give you back is time. One relationship instead of many. One person who knows the whole story, so you stop being the project manager of your own financial life. None of these pieces is that hard on its own. The coordination is what you do not have the hours for. That is the part I take off your plate. I am raising four kids of my own, including a set of triplets, so I plan from inside this life stage, not from a brochure. I know what it costs, in money and in attention, to do this well. If you are tired of being the one who holds it all together, reach out. I will tell you honestly whether I am the right fit.
