Amir N

CFP®, EA

Huntington, NY

N Financial Plans

Hi, I’m Amir Noor—a fee-only financial advisor who specializes in helping high-net-worth clients navigate complex financial and tax planning. As a Certified Financial Planner™ (CFP®), an Enrolled Agent (EA), and Chartered Retirement Plan Specialist™ (CRPS™), I bring a varied lens to your finances: strategic, goal-oriented planning and expert-level tax guidance. I don’t accept commissions, product sales kickbacks, or referral fees—just clear, objective advice that puts your best interests first. My origin story begins on Long Island, where I was raised in an immigrant household defined by entrepreneurial highs and devastating lows. My father, a risk-taking entrepreneur, passed away while I was still in high school. Overnight, I found myself managing our family’s finances and hustling to support us—building websites and offering tech support to local businesses before I was old enough to vote. At 19, I got licensed as an insurance agent and began my journey in financial services. (No, I no longer sell products.) I started college as a computer science major but graduated from SUNY Stony Brook with a finance degree after realizing where I could have the greatest impact. My early entry into the field means I’ve now worked in financial services for nearly two decades—while still in my thirties. That experience spans a broad range of clients, from 22 to 70+, across professions like law, medicine, finance, and entrepreneurship. I’m fluent in their language and the challenges they face, from correcting mismanaged 401(k)s to addressing underinsured households to navigating unexpected windfalls and offshore asset transfers. Clients often tell me I “get it”—because I’ve lived it. I know what it’s like to be the first line of financial defense for your family or your business. And I know how overwhelming it can feel when you're not sure who to trust. That’s why I built my practice around transparency, technical expertise, and deep empathy. Today, I live in Huntington, Long Island, with my growing family. I continue to work closely with attorneys, medical professionals, and small business owners—helping them gain clarity, reduce risk, and build lasting wealth. Let’s talk. And if you have a great restaurant recommendation, we’ll get along just fine.
