### **What is an Outdoor Empowerment Group?**
Our Outdoor Movement & Community Empowerment Groups are simple, guided experiences designed to help people reconnect with nature, themselves, and others. We combine some form of movement (hike, walk, run, bike, yoga, workout) and meaningful conversation within a simple community circle to create a space where individuals can support each other while prioritizing mental and physical well-being.
Whether you’re seeking stress relief, personal growth, or community, our groups offer everyone a unique and welcoming environment.
## **Why Join?**
* **Improve Mental & Physical Well-Being** – Movement, nature, and supportive conversations reduce stress and promote balance.
* **Feel Less Alone** – Build genuine connections with like-minded people in a safe, welcoming space.
* **Gain Clarity & Perspective** – Step outside daily routines and into a space designed for personal growth and reflection.
## **The Ideal Group Leader**
The ideal group leader
* Has a born-in passion for mental health, movement, connecting with nature and building community.
* Has 5 extra hours per week to dedicate to a meaningful cause for at least one year. Yes, you can leave any organization at any time and we can also ask you to leave, but we are building with legacy in mind and we need people who can commit and be ALL IN on this mission to build with us.
* Is independently financially stable with the ability to volunteer with no expectation of pay. This is a deeply beautiful journey of service that all participants commit to at Speak Your Mind.
* An ability to manage groups with high emotional intelligence and desire for human connection.
* An ability to self-motivate and market/promote their group on Facebook and other social platforms.
* Nature informed therapy or clinical therapists/psychologists a plus.
## **Our Impact**

Since launching, we have helped thousands find support, connection, and healing through our Outdoor Movement Groups. 100% of participants surveyed have reported:
* A noticeable improvement in mental clarity and emotional well-being.
* An increase in social connection and a sense of belonging.
* Said they would return again.
We believe mental health should be accessible, community-driven, and rooted in nature. Join us and take the first step toward a more connected, grounded, and supported version of yourself.
### **Why Our Groups are Donation-Based**
Our Outdoor Movement Groups are made possible through a donation-based model. This approach allows us to keep our events accessible to everyone, regardless of financial circumstances, while also ensuring that we can continue expanding our reach. It’s a great way to pay it forward and support the growth of this beautiful mission!
Every contribution helps us:
* **Cover Essential Costs** – Donations allow us to pay essential legal, marketing, insurance, and admin costs as well as nourish the important people who run the organization.
* **Grow Our Mission** – With your support, we can bring these healing experiences to thousands more people in the future and execute our long term plan to expand across the USA, affecting up to 500,000 people per year.
By choosing to contribute, you’re not just leading an event—you’re helping build a mental health movement that supports long-term well-being and connection for all during a severe mental health epidemic.

We’d love to have you be part of this growing community of people prioritizing their mental health, movement, and connection.

These Meetups are co-ed, super laid back, and all skill levels are welcome. Post your skill level and a suggested court in the comments section so we can round up as many players as we can for some tennis fun!
Also, if you’re looking to meet new practice partners or play some matches and you aren’t already in the PlayYourCourt Community, you can go here to see what we’re all about and sign up:
https://www.playyourcourt.com/tennis-community/columbus-oh/meetup/

CMG Gives Back: Serve Brunch at FAITH MISSION GRANT KITCHEN!
Join us as we get together to get together to help those in need at this CMG Gives Back event! We have a great little community of Movie Group friends so rather than see a movie this time, we’ll help “create a better world” by helping serve those in need. Here are complete details and our plan for this event:
FAITH MISSION – GRANT KITCHEN: The Faith Mission kitchen and dining room serves residents 3 meals a day, every day of the year. For this event, our group will help prepare food, serve meals, assist residents in the dining room, wash dishes, and clean surfaces.
PLAN: We will be preparing / serving / cleaning for BRUNCH from 10:30am to 12:30pm and have space for a total of 7 volunteers. Please arrive at 10:20am and wear closed-toe shoes and long pants.
LOCATION: Faith Mission – Grant Kitchen is located at 245 N. Grant Ave. Enter the kitchen at Dock 1 (in the back of the building), indicated in the attached map. On-site parking in the adjacent lot and street parking is available in the surrounding area. Below are some links / attachments with additional info/details:
IMPORTANT REMINDER: Our group will be providing all of the volunteers on this day so a firm RSVP count is essential. Please only sign up if you are certain you’ll be able to attend. If something unavoidable comes up, please try to update your RSVP no later than one week prior to the event. With few exceptions, no shows or cancelations within 1
week of the event will not be eligible for future CMG Gives Back events. I appreciate your understanding as we try to ensure the agencies have the volunteers needed to provide the essential services they provide to the vulnerable population they serve. Our Partner Agency for this event is Lutheran Social Services! A huge THANK YOU to all of YOU for volunteering at this (and any of our previous) CMG Gives Back events!
Should be another good/fun/meaningful time together, Dan
