Please wear appropriate hiking shoes.

**The idea for this group is to build a community where men can gather together and build connections & learn and grow from each other.** How we start each meeting is by each of us checking in with our "roses and thorns" aka what are the good things and the bad things going on in your life recently? Then we will go into a topic discussion. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **COMMUNITY AGREEMENTS** \*\*THERE WILL BE A ZERO TOLERANCE POLICY FOR NO-SHOWS.

Confidentiality - EVERYTHING that is shared NEVER leaves this space so that this space remains safe and sacred. There is a zero tolerance policy for this. If a man is in violation of this, they will be permanently removed from the group. 2. Non-Judgement - we respect and honor every man’s truth so that we may receive the same from others.

Be committed - honor your commitment to this group and to yourself. If you attend a meeting, please commit yourself fully to the meeting. Also be committed to your own journey. When we fail, we own it & clean it up. 4. Speak from the heart - this is NOT a space to “look good”, have the “right” answers, and have it all together. Relax and know you are not alone. Be exactly who you are within the safety of this space. 5. Be supportive - This means always willing to provide encouragement to your fellow men, encourage action and momentum in each other’s lives.. Be willing to challenge each other. Be willing to hold each other accountable. 6. Participation - what you receive from this community will be a reflection of what you put into it. Period. We ask that you share your perspectives, reflect on others, and give/receive support when and where it’s needed.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

**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.
