Employment Litigation Attorney

VP Emerita UN Women | Attorney Action Figure 🦸🏻‍♀️ | Arresting Author | Chief Negotiation Officer | Plucky Podcast Host | Irreverent Int'l Keynote | "What Box?" Bellwether

📚 World domination through literary seduction. Elegant. Defiant. Irresistibly true. Are you ready for what's next (October 13, 2025)? MY WRITING IS ORGANIC USING REAL INTELLIGENCE (AI wishes it could write like me)

I'm not bossy. I'm BOSS. A UN Women VP, provocatrice, attorney/law professor turned negotiation GOAT . . .

(Buckle up. This is ..."a lot")

🦸🏻‍♀️ I help women harness the power of everyday negotiation—from conning a toddler into eating peas to running the boardroom. I authored the Little Black Dress of negotiation books. Why?

Because negotiation isn’t just for business. It’s everybody’s business 🧐

(But you don’t need me to “empower” you. Nor do I sell a “masterclass” or certification from my own “institute”)

🌍 World Mediation Peace Activist. Benevolent & incurable explorer (dubbed “creative savant”—you know who you are). A bit wild at ❤️‍🔥, I struggle with purpose and disrupt with goodwill—through advocacy, teaching, writing, broadcasting, philanthropy, art & sports.

🗣️ Polyglot. Passionate about people & social progress. JEDI agent (not a Star Wars ref). I’ve practiced law in private, public & non-profit sectors; have taught internationally, including over two decades as faculty at two University of California law schools.

I get that people are messy multitudes—and how they actually behave in conflict & decision-making.
What makes me next-level? Decades of deep experience in negotiation, behavioral economics, game theory, plus dope training in:

✔️ Emotional micro-expressions
✔️ Lie detection
✔️ Neuroscience & decision analysis

Oh, and I know the #1 most stealth negotiation skill. 😎

(Kinda like x-ray vision. Hint: it’s NOT “speaking your truth.”)

WHAT I’M NOT:

❌ A sales/marketing bro who built my expertise off a “masterclass”
❌ A brand
❌ Your income stream
❌ After your 💰 or approval
❌ One to trademark words. Ahem™ 🙄 (you know the type)

Special needs parent & dog whisperer—chaos doesn’t faze me, and persistence is my default setting. CEO of a 501(c)(3) nonprofit providing dogs & sibling support for families with special needs kids.

🫶 Turn-ons: Cake, shoes, pour-over coffee, decent literature
🤢 Turn-offs: NIMBYism, vapid buzzwords, elitism, posers

💡 Meyers-Briggs type? ENFJ-A (same 2% club as Obama & Oprah).

🕸️See more on pactumfactum.com, but TLDR: 
I’m 95% human Labrador (begs the question: what’s the other 5%?). Find it endearing or annoying. That's on you. Either way, I’ll be me because, as Oscar Wilde said, “Everyone else is taken.”

P.S.
❌ I don’t do casual Zoom coffee chats
✅ I’ve already overpaid it forward
