**\* This is an in-person event** Most people only experience finished products. Very few get the opportunity to work on something before it's finished when it can still be shaped. This is one of those opportunities. Karen Hold, Director of DT:DC, is currently developing a new innovation skills workbook with Jeanne Liedtka, based on over a decade of teaching and working with leaders across organizations, universities, and the DT:DC community. Her work focuses on the five statistically validated skills that help people develop as innovation leaders. This workbook builds on her work in design thinking and innovation education, including programs at the University of Virginia Darden School of Business, École des Ponts Business School (Paris and Casablanca), and Boston College. For this session, Karen will share a draft chapter of her new workbook for live testing. This is not a polished workshop. It's a working lab. You won't just participate. You will help shape the material itself. What We’ll Be Testing: * Whether the exercises actually help people think differently * Where the material is clear and where it breaks * What feels useful vs. what needs to be reworked This is the kind of work that typically happens behind closed doors. **What You'll Do** Working in small groups, you will: * Work through exercises from a draft chapter of the workbook * Apply them to real situations and ideas * Share feedback on what is clear, confusing, or missing * Help identify how the material can be improved You’ll get: * Early access to work that is still being developed * A chance to influence how this material evolves * Practical tools you can immediately apply * A behind-the-scenes look at how skill-building experiences are designed This is a rare opportunity to be part of the process, not just the outcome. Join us if you want to be part of something early, unfinished and actively evolving. No prior experience is required. **About Karen Hold** Karen Hold is the founder of Experience Labs and Director of DT:DC, one of the world's largest innovation communities connecting founders, designers, policymakers, and changemakers. Her work sits at the intersection of teaching and real-world application. She works with Fortune 500 corporations, federal government agencies and non-profit organizations, helping teams strengthen how they think, make decisions, and move ideas forward. She teaches in graduate and executive education programs, including at the University of Virginia Darden School of Business, École des Ponts Business School (Paris and Casablanca), and Boston College. Karen is a co-author of *Experiencing Design – The Innovator’s Journey*, and her work focuses on developing the skills that enable individuals and organizations to navigate complexity and create meaningful change.

Easter is more than a moment in history—it’s a living, spiritual experience. In Unity, we understand Easter as a powerful symbol of **renewal, transformation, and the awakening of new life within us**. It’s an invitation to rise beyond limitation and step into a higher expression of who we are. Join us at sunrise for a peaceful and uplifting Easter service as we reflect on the deeper, metaphysical meaning of resurrection—not just as something that happened once, but as something unfolding in us every day. As the sun rises, we’ll center ourselves in hope, possibility, and spiritual awakening. Whether you’re rooted in Unity teachings, exploring new spiritual paths, or simply seeking a meaningful way to begin your Easter morning—you are welcome here.

Title: Beyond Cryptography: Geometric Symmetry & Parity Stability Summary: Decoding Chaos: Using Quantum-Inspired Symmetry Metrics to Detect Stealth Attacks in High-Stakes Infrastructure. Agenda: Why symmetry matters after the proof is done. Symmetry as an Invariant Symmetry as a Security Primitive Trust as a Continuous Function Live Thought Experiment Engineering, Implications & Open Questions Move away from traditional bit-matching and discuss "Symmetry Drift." Explain how system states can be modeled as high-dimensional manifolds where an attack represents a geometric deformation.T(t)=f(symmetry stability,parity consistency,temporal coherence) Speaker: Vijay Krishna Vijay is a security engineer focused on runtime observability and symmetry drift in cryptographic systems. He is the founder of Vyapti Resonance and the creator of the Quantum Security Probe (QSP), a telemetry-driven integrity monitoring framework for post-quantum infrastructures. His work bridges theory, engineering, and long-lived system behavior, emphasizing measurable trust over binary verification. Vijay has 9 accredited licenses in Quantum Computing. Career Snapshot: Microsoft → DuPont → Rockefeller Capital Management → Morgan Stanley → New York Life → Founder, Vyapti Resonance Across this trajectory, Vijay has operated at the core infrastructure layer of organizations—cloud platforms, identity systems, distributed compute, reliability engineering, and governance frameworks. His work has consistently involved systems that cannot fail, particularly in regulated financial and insurance environments. This enterprise grounding strongly informs his academic and research outlook: quantum and AI systems must be operable, governable, auditable, and teachable, not merely theoretically elegant.

We will participate in a healing journey. This is very powerful and quite healing. This month we will do a past life regression. We will be sharing and discussing some thought-provoking questions. I recommend bringing a journal to record your thoughts. We can share some stories around the fire and then I will close the ceremony. Bring appropriate crystals that you would like charged. The best crystals to charge during a full moon are amethyst, smoky quartz, citrine, black selenite, and obsidian. We will be outside so please dress for the weather. This is a laid-back event at our home, I hope that you can join us. Howling at the moon is optional and encouraged. Please enter the gate on the right of the house behind the green bug.

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.

**Connected Westerville Night of Networking** *April Edition: The Introduction Economy* You've been to the networking events. You've done the small talk. Collected the cards. Forgotten the names. And walked out feeling like you just wasted two hours of your life. The problem isn't you. It's the format. Most networking events put you in a room and tell you to figure it out. So everyone defaults to elevator pitches and business talk, and nothing real gets built. Here's the truth about networking that most people miss: Your network isn't just who you know. It's who thinks of you when they're talking to someone else. *That's* The Introduction Economy. And it only works when relationships are real. There's a reason people who come once keep coming back. It starts with seven minutes that feel nothing like networking. Then we open it up. Free networking. More conversations. More momentum. This is a room full of corporate professionals, entrepreneurs, business owners, creatives, and career builders in the Westerville and Columbus area. The mix is the magic. You might never do business with everyone you meet tonight. But someone in this room will think of *you.* **By name**. So, the next time someone needs exactly what you do, you get the recommendation. **April 14th. RSVP now.** **When:** Tuesday\, April 14th \| 6:15 PM \-\- 8:00 PM **Where:** Vineyard Community Center \| 6000 Cooper Rd\, Westerville\, OH 43081
