Confidence can be cultivated in many ways—through reflection, conversation, creativity, and practice. In this Confidence Lab session, we’ll explore one powerful pathway: **building confidence from the inside out through physical expression and movement**. This experience is designed to help you reconnect with your body as a source of insight, self-trust, and presence. We’ll begin by grounding into what’s bringing you here, creating space to notice how your body is showing up and what it’s holding. From there, you’ll be guided through accessible movement exercises that invite awareness and choice—isolating different parts of the body, experimenting with movement, and practicing what it feels like to take up space intentionally. Next, you’ll participate in a small-group dance lesson led in a supportive, low-pressure environment. No dance experience is needed. The focus is not on performance or perfection, but on expression, curiosity, and allowing yourself to move with confidence as you are. We’ll close with a reflective group discussion, exploring what emerged during the experience and how these insights can be applied beyond the studio—how you inhabit your body, how you carry yourself, and how you show up in everyday life. **What to know:** * Wear comfortable clothes and shoes that you feel good moving in * No dance experience required * Light snacks and beverages will be provided This session is for anyone interested in deepening their relationship with confidence by listening to their body, expanding their capacity for self-expression, and practicing self-love as an embodied experience. **Featured Speaker: Mary Grace** Mary Grace, the dynamic force behind MG Choreography & Boutique, has been transforming special occasions with her unique blend of artistry and passion for over seven years. As a proud Latina, with Venezuelan and Mexican heritage, Mary brings a rich cultural perspective to every choreography she creates. Her dedication to dance is matched only by her commitment to empowering others through the joy and elegance of movement. Mary’s journey began with a simple passion for dancing, which quickly grew into a thriving business. She specializes in crafting personalized choreography for weddings, quinceañeras, and sweet sixteens, ensuring each event is unforgettable. Determined to make a significant impact in Ohio, Mary established the first-of-its-kind brick-and-mortar location that not only offers a space to practice these beautiful dances but also provides a boutique experience for purchasing or renting exquisite dresses and tuxedos for these special moments. Mary Grace is more than just a business owner; she is a trailblazer for Latina women in the community, dedicated to bringing elegance, joy, and a touch of her vibrant heritage to every event she touches. **What is Confidence Lab?** Confidence Lab is a monthly community experience for bold, thoughtful leaders building confidence from the inside out. Whether you’re launching a business, leading a team, navigating change, or simply striving to show up more fully—you belong here. Our work demands clarity, courage, and conviction—but the pace of daily life can erode our sense of self. Confidence Lab creates space to reflect, reconnect, and grow with others doing purpose-driven work. It’s designed for entrepreneurs, nonprofit leaders, creatives, corporate professionals, activists, and anyone ready to lead with authenticity and impact. ***Please note:*** *All are welcome!

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.

**Comedy Night + Open Mic + Freestyle**: We've hired a professional comedian to warm the group up for our open mic session. Members have been making me laugh for years and we've tossed around the idea of a comedy night / open mic. Well, It's time to step up and crack me up. We'll start with Tristan Shae and a couple of his friends. Tristan is an alternative comic from Columbus, Ohio. A counselor by day, Tristan explores how comedy can improve mental health by telling jokes and stories that muse on how absurd life can be from squeaky clean topics to not so clean ones. Tristan produces the variety show Cheaper Than Therapy, hosts the weekly Problem Child Alt Comedy Open Mic at The Attic, and can be found engaging in all sorts of silliness around the city from stand up shows at The Nest Theater, The Attic, or The Funny Bone, to improv and sketch shows with various groups at various venues such as The Hashtag Comedy Club. **On Freestyle night** \- just bring a bottle to share\. There is NO formal wine tasting like on other weeks\. Door charge is $10 \(cash or Venmo only please\)\. We may have some left over wines to clear out\! Glasses are provided\. Take Care\. See you there\. **Parking**: There are several public parking lots near the Alive614 hall. Please be careful to NOT park in private parking lots. They do tow. Check Google maps to scope out your space. Anyone who is early could easily find a parking space on the street nearby. I am told that the Chase parking lot is safe after hours. **Glasses**: …will be provided. Please note that after the wine tasting, the EMPTY glasses need to be returned to the boxes at the service table. Please do not make me hunt down your empty glass. Please be gentle, our glasses are fragile. Uh, they are made of glass! **Food**: You are welcome to bring a snack to share. It is not required. Most people do though. If no one brings anything, there will be nothing. **Code of Conduct**: Though mostly understood, it’s still worth mentioning. We don’t have rules per se, but we highly discourage the following topics of discussion because they are likely to incite anti-social responses - Sex, Politics, Religion. Please don’t mistake this as an attempt to limit your free speech rights but rather a guide to a place and time for appropriate discussions. **After the lights go out**: After the last sip of wine, when we clean up and turn the lights out, if you still haven’t had enough of us, it is typical for a group to get together and go to a local eatery for food and/or drinks or coffee. Again, We look forward to meeting new members and reuniting with old friends. Sincerely, ***Paul Uttermohlen***, **Red 1 Realty** *Your Hilliard Wine Club Host*

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** TBD **YouTube Link** TBA
