Financial Advisors Who Truly Care Like Family
✅ Wealthtender Certified Advisor Review™
Oct 29, 2025
I couldn’t ask for a better team of financial advisors. From day one, they’ve treated me like family — always taking the time to listen, communicate clearly, and make sure I understand every step of my financial plan. What I appreciate most is how they create a strategy that’s personalized to my goals, not a one-size-fits-all approach. They genuinely care about my success and well-being, not just the numbers. Highly recommend to anyone looking for trustworthy advisors who go above and beyond!

We Want Your Voice to be Heard
Wealthtender exists to help people discover trusted and authentic financial professionals and educators who may be a good fit based on their unique needs and circumstances.
Your honest reviews help people decide which financial professionals and educators may be best suited to their individual needs.
The majority of people trust reviews as much as personal recommendations, so what you write in your review should reflect your own opinion and experience.
Tips for Writing a Helpful Review
Be descriptive. Instead of just saying what you like or dislike, share why. What have you enjoyed most or least about your experience with the provider? Have they helped you overcome a difficult financial challenge or strengthened your knowledge about particular money matters? The more details, the better!
Be honest. Your rating and review should reflect your actual experience.
Stay relevant. Ensure your review is helpful to others by avoiding off-topic discussions or personal opinions not relevant to your direct experience.
Make your review easy to read. Reviews should be readable to others. Use proper grammar, avoid excessive capitalization or punctuation, and be sure to check your spelling.
Be yourself. Don’t post as, or pretend to be, someone else, and do not say you’re associated with a person or organization with which you are not.
Be nice. Don’t write abusive, hateful, threatening, or harassing content. Avoid personal threats, hate speech, obscenities, or inflammatory language.
Respect the privacy of others. Don’t post information that can be used to identify another individual or compromise their privacy.

FAQs
What makes you different?
There are three things that set us apart: We go beyond dollars and cents by aligning your financial plan with your values and the life you want to live. Our team-based approach means you’re supported by the expertise of the whole SYKON team, with integrated financial planning, investments, tax strategy, and estate planning all under one roof. Because we’re independent, fee-only fiduciaries, every decision is made in your best interest.
What if my financial advisor isn’t available?
A core tenet of our team approach is that clients are never left waiting on one person. We work as a team, and each member brings their own area of expertise to the table. That means whether your advisor is tied up or out of office, another member of our team will already know who you are, understand your situation, and be ready to step in seamlessly. In fact, part of the SYKON experience is getting to know multiple team members over time. You’ll have a team of professionals who can anticipate your needs and provide consistent, high-quality guidance so you always feel supported and connected.
How do you charge?
We charge either a percentage of your assets or a flat fee. All fees will be presented to you in a clear and transparency way prior to working together and at all times during the relationship. We are fee-only fiduciaries who are bound to put your interests before our own. We follow the fiduciary standard, the highest standard of care in the industry, in all matters concerning our practice. We do not accept commissions as a compensation method.
Do I have to live in New York or Florida?
We work with clients across the country. We have the capabilities and technology to work virtually as well as in person with clients.
Is there a minimum account size?
We work with clients of all portfolio sizes. There is no minimum. Upon request, we are able to provide planning-only services where we solely provide financial planning without managing your assets.
Where will my money be held? Who will have access to it?
Your assets will be held at the custodians, Charles Schwab and Goldman Sachs.
