Growing up as an identical twin afforded Brenda a unique opportunity to appreciate the importance of "Teamwork" early in life. She furthered these skills in high school and college as she held various leadership positions (Honor Society President, etc.). A graduate school program at Tufts University in Nutrition Education and Counselling gave Brenda yet another invaluable perspective which culminated in Brenda's philosophy of working WITH clients so as to best accomplish their mutual goals. Brenda has literally moved across the country from Massachusetts to Indiana, Illinois, Michigan, and ultimately to Danville, California in 1985.

She has maintained an active involvement in her community, including church, schools, athletic offerings, arts, etc. She loves the many facets of living in the Bay area, and delights in sharing the opportunities this area offers.  

Professionally, Brenda is one of the founders of The Blackhawk Real Estate Company, which was acquired in 2009 by J. Rockcliff Realtors. Brenda was awarded the prestigious Five Star Professional Award in 2013. She is an active member of Marketing Masters, a select networking group of twenty real estate professionals representing the area's major real estate offices, and of the Top Agent Network (TAN).

Barry knew he was "home" in 1985 when he discovered San Francisco and the communities of the San Ramon Valley. He loves its beauty, its architecture, its weather, its activities, and its ambience. Mostly, he loves its people, and he feels blessed by God to be able to live here. As a bonus, he is able to work closely with the best real estate agent in the East Bay. That would be Brenda Zwahlen, a broker with J. Rockclif Realtors (also his wife). Perhaps he is a bit biased.
