Common Questions

Frequently Asked Questions

ESG stands for Environmental, Social, and Governance. It's an investment approach that evaluates companies not only on financial performance but also on their impact on people and the planet. At Longwave, we help you build portfolios that reflect your ethical commitments without compromising investment discipline.
As fiduciary advisors, we are legally obligated to act in your best interest at all times — not the interest of a financial institution or product provider. We are fully independent, which means our advice is objective, conflict-free, and always focused entirely on you.
Longwave is built for people who are deliberate about their financial future, interested in values-based or ESG investing, navigating important life transitions, or managing complex workplace benefits. If you have big goals and care deeply about the impact of your financial choices, we'd love to connect.
We offer holistic financial planning, fiduciary asset management, ESG and values-based investing, healthcare financial planning, estate planning support, tax strategy, employee benefits optimization, and charitable giving planning — covering every meaningful dimension of your financial life.
Most advisors optimize for returns. We optimize for alignment — between your money, your goals, and your values. As an independent fiduciary firm with no institutional affiliations or product sales incentives, we bring both rigorous investment management and genuine personal empathy to every client relationship.
Not at all. While ESG and values-based investing is a core strength and passion of ours, our holistic financial planning and fiduciary asset management serve any client who values deep, empathetic, independent financial guidance.
We work with clients experiencing a wide range of meaningful transitions — career changes, inheritance, retirement planning, family growth, and more. Periods of change are exactly when steady, values-grounded financial guidance matters most.
Longwave Financial is based in the Hudson Valley and serves clients across New York. We'd encourage you to reach out directly to discuss how we work with clients in your area.
