About Us
Who We Are
The wealth gap in America has reached a point we can no longer ignore. While traditional financial models often prioritize short-term gains at the expense of community health, Shared Prosperity Group (SPG) was founded on the conviction that capitalism requires generosity to endure. We believe that when giving is absent, trust erodes and the entire economic system becomes fragile. That’s why we pioneered a model where wealth creation and positive impact can finally move forward together.
Our commitment to structural generosity is written directly into our governing documents. Every month, we contribute 10% of our firm’s gross revenue to vetted causes that achieve measurable change. Because we give from our own top-line revenue rather than your personal accounts, this mission never increases your fees or reduces your returns.

Mitzi’s key achievements include:
- Stress Surveillance & Response: Monitoring employee stress levels and intervening with snuggles, tail wags, or strategic deployment of head tilts.
- Security Briefings: Barking at absolutely nothing with unwavering conviction… just in case.
- Conflict Resolution: Specializing in diffusing tension through prolonged eye contact and belly rub treaties.

Thank you, Mitzi! Who’s a good girl? You are!!
