"And so when we have the power of community it enables us to heal. When we have the power of the 361 community, you're able to bring incredible people together, right? And amazing things happen. And that's something that is within the DNA of the 361 firm that I have not seen anywhere else."

"We have the opportunity to discern between what's real out there and really cut through a lot of the dirt to see what's going to have the good, what's going to have ROI and what's really going to move the needle. I think that real relationships are being created. A lot of laughs between last night and today, friends that I think will last forever. And I'm really enjoying the opportunity just to get to know all these people both on a business level and a personal."
