    Last Friday, 30 Updreamers had the opportunity to volunteer at 𝗙𝗿𝗶𝗲𝗻𝗱𝘀 𝗼𝗳 𝗔𝗻𝗶𝗺𝗮𝗹𝘀 𝗦𝗵𝗲𝗹𝘁𝗲𝗿, a local dog shelter in Athens, that’s making a big difference in the lives of abandoned and rescued dogs. We spent the day learning about their mission, walking the dogs, and of course, giving them all the love and attention they deserve. It was an incredibly rewarding experience, seeing firsthand how small acts of kindness can have a lasting impact on both the dogs and our team. Looking forward to more opportunities to give back and make a positive difference together. Follow the link to learn more https://lnkd.in/dCzawWjA #weareupstream #updreamers
