Our “giving back” philosophy is one of our guiding principles.  Both Mike and Lorianna Kastrop serve in volunteer civic positions, not occasionally, but always.  Mike has donated countless hours to the improvement of downtown Redwood City and has been on the Board of the Downtown Business Group for many years, serving multiple terms as President.  In 2016 he was named “Mr. Redwood City” in a scholarship fundraiser by the Miss Redwood City/Miss San Mateo County pageant foundation. 


Lorianna has been in a variety of volunteer public positions, beginning in 1991, including appointments to the Redwood City Housing and Human Concerns Committee and the Redwood City Port Commission.  She also served in elected office on the Redwood City School District Board of Trustees, as well as various non-profit associations, including Peninsula Sunrise Rotary Club, Sequoia YMCA, and Stanford Professional Women.  She was named Businesswoman of the Year in 2001 by the Redwood City/San Mateo County Chamber of Commerce.  She created a foundation for the Sequoia Boosters Club to raise money for high school athletes’ equipment and transportation.  That foundation now raises over $100,000 per year.  She is particularly proud to have been instrumental in organizing a project and raising funds for communication transmission equipment and a medical supply boat for isolated people in the Amazon river region of Ecuador, allowing over 2,000 people to have access to emergency medical care for the first time.  She is also pleased to have been one of the founders of the Redwood City Hometown Holidays Festival, one of the biggest annual festivals on the peninsula.  She is the founder of the Redwood City PortFest, a unique annual opportunity for the public to visit and tour a working industrial port and take boat tours to explore recreational opportunities on the Bay.
