The Paradise Ridge Family

Walter Byck – President / Founder

Pa Head Shot
Walter Byck – Head of the Paradise Ridge Family- was born in Newark, New Jersey. Excelling in all levels of his studies, he graduated from the University of Pennsylvania Medical School top of his class. As radiology resident at Cornell Medical Center in New York City, Walter met his future wife, the beautiful Marijke Hoenselaars. Upon completing his residency, he requested to be stationed in Europe close to the Dutch border and Marijke. Walter proposed after a walk through the sculpture grove at the Kroller-Muller Museum, and Marijke & Walter were wed in Nijmegen, Holland in 1961. Four years later, when Walter joined a small but growing medical group, Redwood Radiology, the young couple moved to Santa Rosa. Walter discovered Paradise in 1977, but it wasn’t until May of 1994 that Marijke & Walter opened Paradise Ridge Winery. The first sculpture exhibit in the new Paradise Woods Sculpture Grove opened within a year, and, upon retiring from medicine in 1997, Walter turned his attention towards building the reputation of his growing sculpture project. In 2004, Walter was recognized for his outstanding efforts in the art community, bringing together numerous art organizations and spearheading a countywide art project known as Sculpture Sonoma. In honor of this major accomplishment, Walter was chosen as ‘Man of the Year’ by the Bohemian.  With a passion for many things, including cosmology, art & wine, Walter is most passionate about his family, especially his 13 grandchildren.

Marijke Byck-Hoenselaars (1933-2006) – Founder

MBH Head shotBorn in Nijmegen Holland in 1933, Marijke Hoenselaars was the second of six children. She grew up during World War II and her earliest memories include her parents opening their home to nine families who had lost their homes to bombing. Always a hard worker and wonderful student, Marijke was chosen to go to America to study nursing in New York City, where she met her future husband Walter Byck. The couple moved to Santa Rosa in 1965 and purchased the Paradise Ranch in 1978. Their five children were raised mostly on the 155-acre property. Taking advantage of the beautiful site in the hills on the edge of Santa Rosa, Marijke, Walter and their family opened Paradise Ridge Winery in 1994. Marijke was a natural leader and for 12 years she was CEO of the winery. Tragically Marijke was killed in a car accident in January 2006. Her legacy is marked by her tireless efforts, frequently performed anonymously, on behalf of the less fortunate in Sonoma County. From delivering food packages and holiday gifts for children of low-income families, to serving as a Board Member, benefactor, and leader with numerous local nonprofit groups, her helping hand and personal involvement were the hallmark of her style. Marijke’s compassion led to her participation in the Sonoma Task Force for the Homeless, the National Women’s History Project, Catholic Charities, The Children’s Village of Sonoma County, UNICEF, as well as many others. She also cared deeply about global peace issues, and her activism reflected these broader concerns as well. Her service to the less fortunate went beyond compassion. Whenever she went out to dinner, she boxed what she had left and did not go home till she found a hungry recipient. The spirit of Paradise Ridge Winery’s founder and leader continues to inspire us everyday.
