I was referred to Michael Sonza to manage a portion of my IRA and initially started with a smaller allocation before transitioning more of my portfolio over time. His approach is thoughtful, disciplined, and transparent. He took the time to understand my risk tolerance and clearly explained his investment philosophy, expectations, and fee structure. Over the past few years, my portfolio has seen meaningful growth, and I’ve come to value his steady, long-term approach and accessibility whenever questions arise. I’ve found him to be a trustworthy steward of my capital and would recommend him to those seeking a more deliberate and relationship-driven investment experience.

Working with Michael has been one of the most positive investment experiences I've had. What sets Michael apart is not only his investment expertise, but the level of personal attention and communication he provides. Unlike many advisors who may only reach out a few times a year, Michael is consistently available and proactively communicates with clients. Whether through regular portfolio reviews, market updates, or one-on-one conversations, he ensures that I always understand what is happening in my portfolio and why. The combination of disciplined investment management, ongoing education, transparency, and exceptional client service has made Michael a trusted advisor to me and my family. I highly recommend him to anyone seeking a knowledgeable, engaged, and client-focused investment advisor.

I’ve been a client of Michael’s since 2018, working with him on both my business and personal accounts. What I appreciate most is how involved he stays. He works through decisions with me, is available when it matters, and brings a steady, practical perspective. Michael takes the time to share his insights on market conditions, economic developments, investment opportunities, and potential risks. His ability to explain complex topics in a clear and understandable manner has given me greater confidence in my long-term financial plan. The results have been strong, but just as important is the level of trust and consistency he’s brought over the years. That’s what’s kept me with him.

★★★★★

I wanted an advisor who understood the market but also understood me. Mike Sonza completely exceeded my expectations. He brings incredible strategy to my portfolio, but he is also incredibly patient—always willing to listen, explain anything I don't understand, and guide me through important choices. Thanks to his guidance, I have both incredible growth and complete peace of mind.

★★★★★

I was introduced to Michael through a friend and engaged him to manage both my portfolio and an account for my child. I particularly appreciate his hands-on approach. He is accessible, responsive, and genuinely invested in helping his clients succeed. I never feel like just another account number. Every conversation is thoughtful, informative, and tailored to my specific goals and circumstances. His approach is measured, transparent, and consistently thoughtful. I’ve been very pleased with the results and appreciate the confidence that comes from having a steady, long-term perspective applied to both.
