Meet the RCPNA Board


Tamara DeRidder (Chair)

I am second generation immigrant from Belgium on my Dad's side and my Mom has Scottish heritage. Both parents are educators from Michigan that raised a large family south of Knoxville, Tennessee. I moved out to Portland in 1985 with my partner and soon began my graduate program in Urban Planning. We moved to Rose City Park in 1986. I have served as a land use planner in the Portland-Metro area since 1990: Planning Director/Manager in Cities of Sandy, Oregon City, and Fairview, Oregon; Long Range Manager of Vancouver, Wa; and my own practice as TDR & Associates since 2007. I have been a member of the RCPNA Board twice. Once for a brief period while working at the City of Sandy and then again starting in 2008. I have served on the Land Use and Transportation Committee this whole time and am currently the Chair of that Committee. I was elected as the Chairwoman of RCPNA in 2014.

Since I began on the RCPNA Board in 2008 I have seen it as my role to empower members of our community by teaching them the tools they need to respond to local issues - primarily having to do with land use activity. I led the 3+-year planning and implementation of our Community Garden at Frazer Park that opened in 2012 with my goal in 2008 to provide those without land a place to raise food during the depression that began that year. Since I began on the Board the number of participants on the Board has grown from 9 to 15 members. I supplied the first 350 email addresses gathered from land use meeting participants over the years as the basis for our MailChimp e-Updates. I am very excited about the work of our committees and continually impressed by improvements made by our Communication's team to the website, newsletters, and signage. It is my hope that through our expanded use of the NextDoor blog site, invitation postcards, and event signage we will be able to expand our communications platform to become more inclusive of both businesses and residents of our wonderful community.

Stephanie Singer (Vice Chair)

Stephanie Singer, Data Scientist, has assembled, analyzed and explained data for private business, public agencies, campaigns and election oversight. Her public service projects -- such as the VoteVisualizer -- have been funded by the National Science Foundation and the Knight Foundation. Her client list includes the Orange County Registrar of Voters and the nonpartisan nonprofit Verified Voting. In 2019 she joined the faculty of the Hatfield School of Government at Portland State University, where she finds new ways to apply data science to election cybersecurity. From 2012-2016 she served on the Philadelphia County Board of Elections -- including one year as chair -- where she made data freely available, used data analysis to fight unconstitutional burdens on the voting process, and introduced "I Voted Today" stickers to all Philadelphia polling places. She won the post by defeating a 36-year incumbent in a citywide election. Singer co-chaired the statewide Election Reform Committee of the County Commissioners Association of Pennsylvania and is an active member of the national Election Verification Network. Singer studied math and computer science at Yale and Stanford, completed a Ph.D. at New York University and earned tenure from Haverford College. She has written two books on mathematical physics.

Jennifer Santhouse (Secretary)


Jennifer grew up on the East Coast and moved to Portland with her husband Bob Graham in 2008. While walking through the neighborhood, Bob and their chocolate lab, Bernie found their dream house and moved to Rose City Park in 2012 just in time to welcome their son.  Two years later, their home was filled with more joy with the arrival of their daughter.  Now Jennifer spends her free time gardening, running and attending sports events for their two young children.

In addition to her new role on the RCPNA Board, Jennifer volunteers as a member of the Communications Committee which publishes the Rose City Park Review and is working toward her Neighborhood Emergency Team certification.  Her other philanthropic endeavors include the YMCA of Columbia-Willamette Association, Hollywood Rose City Little League, Immigrant and Refugee Community Organization and various animal welfare organizations.

Richard Crockett (Treasurer)

Richard and wife Jeanette have lived in Rose City Park for over 30 years. A retired middle school math teacher, Richard serves as the treasurer of RCPNA and also does the same for The Rose City Timberliners, a local male barbershop singing chorus and for the Genealogical Forum of Oregon. He is a long- time volunteer and supporter of All Classical radio (89.9). He currently works as the Program Operations Director for Chess for Success, a leading non-profit provider of after school programming in Oregon and southwest Washington.


Kelly Davis

Kelly moved into Rose City Park in 1981 and got involved in the neighborhood shortly thereafter under the urging of a co-worker who was actively involved in the Comprehensive Plan updates for RCP and other issues. As an Architect, Kelly naturally gravitated to Land Use and Transportation (LU&T) issues. He soon became close with the then Chairman of the RCPNA, George Walker. George and Kelly were co-chairs of the neighborhood for a couple of years before Kelly became Chair – the beginning of a 17-year run. In 2010, Kelly was transferred to his company’s Washington, DC office and ran that office until his return to Portland in 2017. He rejoined the Neighborhood Association and is currently Co-Chair of the LU&T Committee. Kelly lives in a 1907 Victorian (one of the first houses built in RCP) with his wife Jackie. He has two daughters – Kelsie who is the DA for Union County Oregon and Courtney who is a Structural Engineer in Portland. Kelsie and husband Kyle had his first granddaughter (Addie) in 2017, which pretty much accelerated his move back to PDX. Kelly retired in 2017 from ZGF Architects and is happy to be back in the Rose City.

Terry Parker

Born in Portland and starting at the age of four, Terry grew up in the Rose City Park Neighborhood attending Charles Rice, Rose City Park and Madison High schools. Continuously living in the neighborhood, now retired and serving as Rose City Park Neighborhood Association Board member and on the Land Use and Transportation Committee; most of Terry's career was in the yellow page industry as a National Account Representative working with Customer Marketing Representatives hired by national corporations to place advertising in up to 300 yellow page directories within a 14 state region. Terry also has held positions in automotive related fields and as a Supply Center Manager for a three state savings and loan.

In the 1970's, Terry served on the four year Oregon Department of Transportation Banfield Transitway Citizens Advisory Committee. He chaired the committee in the last two years as the only elected chair. The committee recommended the region's first modern light rail system from Portland to Gresham coupled with widening the Banfield Freeway (now I-84) between I-5 and Gateway.

In the 1980's, Terry served as the Vice President followed by three years on the Board of Directors of the Pacific Northwest Chapter, National Railway Historical Society. Terry was involved with the Excursion Committee preparing budgets, trip guide booklets and hosting on charter Amtrak excursions; and on the Rolling Stock Committee helping with the restoration of various pieces of rail equipment including the Southern Pacific 4449 and the Spokane Portland and Seattle 700 - two of the steam locomotives now housed at the Oregon Rail Heritage Center near OMSI. One of Terry's fondest memories was flying to New Orleans in 1984, visiting the Worlds Fair and then staffing the return to Portland of the Louisiana World's Fair Daylight excursion train which included the special privilege of riding in the cab of the 4449 from El Paso, Texas to Deming, New Mexico.
