The hit sitcom “The Golden Girls” from the 1980s and early 1990s has a surprising resonance for Casselyn Feinstein, ABR, SFR, especially because it debuted when she was just one year old. The hit song that was the show’s theme famously starts with the line, “Thank you for being a friend.” It’s a sentiment that Feinstein has carried from her earliest days into a thriving career. She builds lasting friendships with many clients by being straightforward but also patient, even when the subject veers off of real estate and into personal woes. Sometimes, “they just want someone to listen.” she says. But as friendly as Feinstein is, don’t mess with her: She’s a Brazilian jiujitsu-trained fighter who has trained others in self-defense techniques.
