Communication is everything in life You are only as successful as your ability to communicate. \- What if you could confidently talk to anyone? \- What if you had the ability to calmly control every conversation? \- What if you could close that sale\, ask for that date\, make new friends\, repair problematic relationships\, get that raise\, or effortlessly express any idea with confidence? You can! The secret to success relies on your ability or inability to effectively communicate. Attend a free seminar and gain a better ability to communicate. Hosted by the Church of Scientology of Central Ohio 1266 Dublin Road, Columbus, OH 43215 For more information, contact Rhiannon, the Event Host at 614-221-5024

**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. IF YOU RSVP TO A MEETING AND FAIL TO SHOW UP WITHOUT NOTICE, YOU'LL BE REMOVED FROM THE GROUP. THIS IS TO PRESERVE THE INTEGRITY OF THE GROUP\*\* 1. 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. While we may not agree on everything, we commit to respecting every man’s perspectives and engaging in honorable discussion with one another. 3. 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.

**Complex Trauma Support Group** Our group is intended for survivors of complex trauma. If you are here, it’s likely that so much of who you are and what you have experienced in this life is actually invisible to most people––to family, society, coworkers, and the people who are around you. We are a peer-led group of survivors creating opportunities for ourselves and others to share our experiences, share support, and build relationships in kind community together. Survivor experiences might include: child sexual abuse, incest, child trafficking, and other experiences of people living with traumatic dissociation and complex PTSD. **What to expect at your first meeting:** Currently, we are offering a bi-monthly in person group at 2:00pm on the first and third Sunday of the month. The only criterion for joining the group is that you are a survivor of trauma wishing to have more kindness in your own life and share kindness with others, and that you agree to practice to group’s relational agreements available for view here: https://www.kindgroups.com/agreements. Joining the group is free of charge. We ask that new people connect with us for 30 minutes on the phone or on zoom before coming to their first group, so that we can determine together that we are a good fit. Our meetings last approximately 90 minutes. Participants are never required to share. You’re also welcome to choose a pseudonym and you will never be asked for private information. You are welcome to leave at any time. The kindness that survivors can share when among others who have survived similar childhood experiences is something we rarely get to experience. Time spent with others who understand even a little bit more about us is a relief. Our hope is to help ourselves and others experience that we are not alone. We wish for our efforts to be a cause of kindness in our own lives and the lives of each other. You can read more about the groups at www.kindgroups.com.

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.
