Our personal Realtor and #1 Referral

Karen is not only our personal realtor who was such a gift as we navigated our first California home purchase after relocating, she's also the first person we reach out to when friends or a relocating staff member asks about a realtor. She's a tireless advocate, a candid advisor, and an all around joy to work with!

Easiest Sale We Have Experienced!

I’m Charlie Blek and I’m a retired attorney. While practicing I was involved in a substantial number of escrows here in Orange County. Karen Quinn was our realtor who handled the sale of our home and the transition into Reata Glen. I appreciated her professionalism as the sale and move was the easiest we had ever experienced.

She Helped me Sell AND Purchase!

I recently used Karen Quinn and her crew to sell my condo AND purchase a new condo. Karen did a fabulous job! She sold my condo for well over my purchase price which helped me with funds to purchase my new condo. Karen was always available or made sure one of her qualified staff was available to answer any questions I had. I would highly recommend Karen Quinn and Regency Real Estate Brokers.
