About Diana

Diana famously got her start in real estate in the 80’s managing 27 of her own apartment units while still maintaining the status as the #1 sales agent at her brokerage at that time. Experience matters and Diana has earned her stripes with over $100 million in career sales, and decades of practicing real estate. Steady and calm, she is a skilled negotiator with a never-give-up, can-do attitude. Diana also has a high-level sports background, having played collegiate volleyball and former competitor on the women’s racquetball pro-tour. She is too modest to share this, but Diana once won the U.S. Open Racquetball National Championship. Despite her unfailing graciousness, Diana maintains the competitive zeal that made her a champion, contributing to her success as a negotiator. As soon as clients meet her, they can tell that she treats her clients like family. Outside of real estate, Diana can be found on the golf course, playing with her grandchildren, watching The Voice, getting together with friends, and most recently, CrossFit!

Diana is also a certified stager!
