Modern Wealth Management Boise

(formerly Petso Financial and Gem State Investment Advisors)  

Your financial life is about more than your portfolio. It’s about the retirement you’ve worked toward, the legacy you want to build, and the confidence to enjoy today while preparing for tomorrow. Modern Wealth Management’s Boise office brings the full Modern Wealth Advantage to the Treasure Valley. We believe in a fiduciary approach to wealth management. Our advisor teams include specialists in financial planning, investments, taxes, estate planning, and insurance that work together for you. 

Enjoy. Prepare. Connect. 

At Modern Wealth Management Boise, our goal is the same as it is across every office in our network: to help you enjoy today with confidence for tomorrow and connect you to the people and causes that you care about most. That’s the Modern Wealth Advantage, and it starts with a conversation. 

A Team Working for You 

One advisor can’t be an expert in every part of your financial life. That’s why the Modern Wealth Advantage is built around a team. Your Boise advisor works alongside specialists in taxes, estate planning, insurance, and investments, who all collaborate on a plan that covers every part of your financial picture. It’s the kind of coordinated, comprehensive advice typically reserved for the ultra-wealthy, now available right here in the Treasure Valley. 

Advantage Offerings: Boise  

Keep more of what you’ve earned. 

Tax planning isn't a once-a-year event; it's a year-round strategy. Our Boise advisor team works alongside Modern Wealth's tax professionals to align your investment decisions with your tax situation, optimize the timing of income and distributions, and help ensure you're not paying more than necessary. Tax preparation services are also available. 

Investments that support your goals. Nothing more, nothing less.  

We believe investments are the fuel that powers your financial plan, not the other way around. Our Boise team builds risk-managed, tax-efficient portfolios aligned with your specific goals and timeline, using a disciplined approach built on low-cost index funds and ETFs. We take only the risk required to help you get where you want to go, and we stay connected to your plan as markets and life change. 

Setting you up today for your legacy tomorrow. 

Estate planning is key to enjoying life today while building confidence for tomorrow. Our Boise estate specialists work with you to confirm your wishes, clearly document them, and ensure they're aligned with every part of your financial plan. From wills and trusts to beneficiary reviews and succession planning, we help you protect the people you care about most. 

Planning for the unexpected. 

A strong financial plan includes protecting against what you can't predict. Our Boise team evaluates your existing coverage, identifies gaps, and recommends solutions that integrate with your broader financial plan, preserving your lifestyle and your savings so that life's unexpected moments don't derail your progress. 

 

Measure Your Confidence

The Modern Confidence Score is a tool to help you understand how confident you are in your financial plan. We’ll work together to increase your score as we connect you to our Advantage Offerings.

FAQ's

What is a Registered Investment Advisor (RIA)?

A Registered Investment Advisor (RIA) is a person or firm that provides investment advice and manages portfolios on behalf of clients. RIAs are registered with the SEC or state securities regulators and are held to the fiduciary standard, which requires them to act in the client’s best interest and disclose material conflicts of interest. When you work with a Modern Wealth advisor in Boise, you're working with an RIA focused on aligning recommendations with your financial goals and best interests.

What does it mean that your advisors are fiduciaries?

Fiduciary is more than a word we use in our marketing; it's a legal standard established under the U.S. Investment Advisers Act of 1940. It requires our advisors to act in your best interest at all times, to eliminate or fully disclose any conflicts of interest, and to place your goals above everything else. That commitment is foundational to how the Modern Wealth Boise team works.

What is your investing philosophy?

We believe your investments should support your goals, not the other way around. Our Boise advisor team builds portfolios around low-cost index funds and ETFs, complemented by individual stocks and fixed income where they add real value. Certain academic and industry research has shown that diversified, lower-cost portfolios have historically compared favorably to many actively managed funds over longer time periods. As a result, we generally favor cost-conscious portfolio construction when appropriate for a client’s objectives. We take only the risk required to help you reach your specific goals.

What makes Modern Wealth different from large national financial firms?

At large firms, advisors often carry hundreds of clients and operate under sales quotas, product mandates, and profit targets set by corporate management. Our Boise advisor team works differently. Because we're part of a collaborative, independent firm, our advisors can dedicate genuine attention to each client relationship, working alongside specialists in taxes, estate planning, and insurance to deliver a coordinated plan, not just investment management. Our clients get the experience typically reserved for the ultra-wealthy, right here in the Treasure Valley.

How is Modern Wealth Boise compensated?

Our compensation comes directly from you, our client. It never comes from commissions, referral fees, or third-party payments of any kind. That structure ensures our advisor team has one priority: helping you make progress toward your goals. There are no competing incentives, and no products we're paid to promote.

How do I know if Modern Wealth Boise is the right fit for me?

The best way to find out is by establishing your initial Modern Confidence Score during a conversation with our Concierge team to assess your confidence across all areas of your financial life, including taxes, estate, insurance, and investments. They'll learn about your financial situation and life goals, answer your questions about our services, and connect you with the right advisor team for your needs. Our Boise advisors will then develop an actionable financial roadmap based on your cashflow, savings, and goals and build projections for your financial priorities. And at each review meeting, we’ll continue to address gaps identified by your Modern Confidence Score with the goal of helping you enjoy today with confidence for tomorrow. We work primarily with individuals and families who have $500,000 or more in investable assets, though we evaluate each situation individually. At minimum, you'll come away with useful perspective, and we think you'll get a clear sense of whether this is the right partnership.

Does Modern Wealth serve clients in Boise, Idaho and the Treasure Valley?

Yes. The Treasure Valley is home for our Boise advisor team. We serve individuals, families, and business owners throughout Boise, Meridian, Nampa, Caldwell, Eagle, Star, and the surrounding Treasure Valley region. We also work with clients across Idaho and nationally on a remote basis. Get your Modern Confidence Score today to start a conversation with our Concierge team, and we'll connect you with the right advisor for your situation.

What is a fiduciary financial advisor, and why does it matter?

A fiduciary financial advisor is subject to a legal duty to act in the client’s best interest and disclose material conflicts of interest. RIAs operate under a fiduciary framework that differs from the regulatory standards applicable to many broker-dealers. All Modern Wealth advisors, including our Boise team, operate as fiduciaries. When you work with us, our recommendations are designed to align with your financial goals and circumstances.

Do you offer retirement planning services in Boise, Idaho?

Retirement planning is one of the core reasons Boise and Treasure Valley families come to Modern Wealth. Our advisor team helps you model Social Security timing, healthcare costs, tax obligations, and income projections to build a retirement plan designed to give you confidence in every scenario. We want you to enjoy today knowing tomorrow is covered.

What happened to Petso Financial Consultants and Gem State Investment Advisors (GSIA)?

Modern Wealth Management welcomed registered investment advisory firms Petso Financial Consultants and Gem State Investment Advisors into our family in 2024 and 2026, respectively. Both based in Boise, Idaho, Petso Financial was founded in 2001 by Dave Petso, while GSIA was founded in 2010 by Ron Gambassi. Dave, Ron, and the rest of the Boise team continue to serve their clients here and are backed by the full Modern Wealth Advantage, including specialists in taxes, estate planning, and insurance.

Does Modern Wealth manage 401(k) plans for Boise-area employers?

Yes. We work with Boise and Treasure Valley businesses to design, manage, and provide fiduciary oversight for company retirement plans. Our services include plan design, investment menu selection, compliance support, and employee financial education. We help employers fulfill their fiduciary duty to plan participants while helping employees build the confidence to plan for their own futures.
