Meetup has been an incredible platform for us to build and connect with our community. We’ll continue sharing upcoming events there so that new people can find us, but Luma will be our primary registration platform moving forward.
**Why we're making the switch**
Meetup’s registration system has some limitations, and we need more flexibility to manage sign-ups and engagement.

Donuts, 1:1 Entrepreneur Chats & Deep Work @ MLK Library
**This is a relaxed but intentional Saturday hangout for young entrepreneurs.**
***Note:*** *Only 10 spots are available to RSVP on Meetup, but the event capacity is **40 people total**. Please join the waitlist and I will approve additional attendees until we reach the 40-person limit.*
We’ll meet at MLK Library for donuts, co-working, and structured 1:1 conversations.
Instead of sharing in front of the whole group, we’ll rotate through casual 1:1 chats where you can:
• Talk through a business blocker or something you want to improve
• Get perspective and ideas from others on how to move forward (whether that’s getting through the blocker or executing the improvement)
After the 1:1 rotations, we won’t just leave with ideas -
we’ll actually start working on the thing you discussed, using the perspective and ideas you received to begin moving through the blocker or executing the improvement.
Whether that’s:
– Fixing your landing page
– Outlining your launch
– Sending the email you’ve been avoiding
– Or clarifying the path forward on something you’ve been stuck on
**You’ll leave having made real progress.**
No pressure. Just entrepreneurs helping each other move forward - and then actually putting in the work.
Bring:
• Your laptop
• One thing you’re ready to improve
• An open mind
I’ll bring the donuts ;)
**If you want to build things with people - not alone - this is for you.**

Spring Weekend Retreat
Ready for an overnight retreat? Our weekend retreats are a great place to start if you’ve established a mindfulness practice or taken a mindfulness class and you’re ready to take it to the “next level.” A weekend retreat is also a wonderful way to renew and refresh a long-standing practice. Our lives as mindfulness practitioners deepen when we’re ready to enter into the sustained practice of retreat.
This residential retreat will be held mostly in silence at the beautiful [Samish Island Campground and Retreat Center](https://www.campsamish.org/) and will include a series of gently guided mindfulness practices including sitting meditation, walking meditation, gentle yoga, and the body scan.
Informative talks on the process of being on retreat, mindfulness, stress reactivity, and other topics will be presented by the instructor. Small and large group discussion at the beginning and end of the weekend will center around our experience together walking, sitting, and breathing in the quiet of the beautiful retreat site.
### SCHEDULE DETAILS
* Starts Friday with 4pm – 5pm check in followed by dinner and an orientation, after which we will begin our silence.
* Saturday is a full day of silent practice (6:30am to 8:30pm with breaks after the meals).
* Sunday is a short morning practice period, followed by breakfast and closing activities.
* The retreat concludes at about noon on Sunday after cabin clean up, with a sack lunch provided for the road.

Omnipresent Atheists Weekly Meetup (1st Tues)
Jimmy V's Grill & Pub in Grandview Heights. You are responsible for your own meal/drinks. We usually don't have any agenda other than eat, drink and talk. :) If the weather is nice we will be on the back patio, otherwise we are in the cigar room.
This group has been meeting every Tuesday evening for over a decade. Many attendees do not RSVP on meetup. Please don't let the small number here discourage you. Anyone/everyone is welcome to come. We'd love to have you join us.
COTA bus #5 comes to W. 5th and Wyandotte Rd. And it's a minute walk to the restaurant.
Did you know that there are atheists everywhere?!?! You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches! So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'!
Vision: a Central Ohio that accepts atheism as a viable alternative in all areas of public and private life.
Mission: grow, support, and provide community for atheists in Central Ohio.
Social meetings held most Tuesdays at a local pub/restaurant at 7:00 PM (and often into the wee hours). Attendees call themselves agnostics, skeptics, humanists, non-theists, deists or even theists. All attendees are welcome but should support our vision.

It was a member of Columbus CoR and held weekly meetings, mostly on Fridays, for several years but then operated as an online only group for some time. In November 2018, Omnipresent Atheists (OA), a group that routinely meets on Tuesdays, invited AoC to merge.

ServiceNow's Got Talent
Builders, creators, architects, admins, consultants - come one, come all. This one's for you.
We're bringing a little friendly competition to the Columbus ServiceNow community while highlighting the cool things people have built on the platform.
Five presenters will take the stage to showcase something they've built, solved, designed, or imagined on the ServiceNow platform - and a panel of judges (plus YOU, our amazing audience) will score them live.
So basically, America's Got Talent but make it ServiceNow's Got Talent.
Bring a notepad if you'd like 'cause you'll definitely be learning something new.
Each presenter gets 10 minutes max to wow the crowd with:
• A demo
• A real-world business solution
• A bold idea
• A UX transformation
• Or a creative use of the platform
Judging Criteria:
🏆 Business Value
🚀 Innovation
✨ User Experience
This event is about celebrating ideas, sharing knowledge, and showing how ServiceNow can drive both business impact and meaningful user value.
Come learn. Come support. Come get inspired.
Refreshments and bites will be provided.
And maybe next time… you’ll be on stage.

DoJo (Informal Python Meeting)
**New Dojo Location!**
**Knotty Pine Brewing**
1765 W 3rd Ave,
Columbus, OH 43212
We're going to try a new dojo location for a few weeks and see how it works
Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead.
We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)
In-Person Event: The Answers to Depression & Anxiety
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.
From Web Forms to Web Components - Burton Smith
**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**
Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively.
This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way.
