Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems.

Libera Animae is an interfaith community focused on inner growth, creativity, and authentic connection. All backgrounds are welcome.

This is a free in-person meeting. Let's talk about relationships in such a way that you can really benefit from the knowledge. We can talk about * Soulmates * How to start a relationship * How to maintain a relationship * How to pick the right partner * How to recognize the red flags * How to improve communication * How to avoid argument and fights * How to increase trust You ask the questions, we'll talk about them.

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

**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.
