  • Owner, GSI Builders, Inc.
Lina Garcia Seabold brings over 30 years' experience in the construction industry in both the public and private sectors. Her experience in the construction industry was acquired through contract management, contract administration, small business advocacy and human relations training, all of which helped her gain real world knowledge and expertise needed to facilitate transformative change in professional lives, businesses, and organizational culture change initiatives. Among her leadership roles, Lina's experience includes work on two design/construction phases of the Tri-Met Light rail Projects (Eastside and Westside) where she administered the Disadvantaged Business Enterprise (DBE) Program. In this capacity, she worked with national construction companies bidding on large and small scale federally funded construction projects working toward meeting specific diversity goals. This effort led to record-breaking heights of participation and support for small businesses especially minority and women-owned businesses who had historically been underserved. She identified and developed contracting, mentorship and workforce development efforts for local construction industry companies in the Pacific NW. Lina went on to work on legislation for the State of Oregon's First Minority Business Advocate in the Governor's Office and served in that initial role. In this position, she oversaw the certification process for Minority, Women and Emerging Small Businesses and advocated for those businesses by bringing them together with key procurement representatives at Federal, State and local levels. Lina has a passion for bringing diverse voices to the table to realize common goals and has dedicated much of her professional career to the goals of Diversity, Inclusion and Equity. In terms of the private sector, Lina is part owner of GarciaSeabold Investments, LLC, which has managed several Senior Housing facilities that provide independent, assisted and memory care services to Seniors in the Western Region: Washington Gardens in Oregon, Canyon Valley Memory care and Hacienda Crossings Assisted Living and Memory Care both in Arizona. In her role at GSI Builders, Lina, who is 100 percent bilingual in Spanish and English, is involved in the executive day to day management of the company overseeing outreach and marketing, human resources, finance, COVID-19 health and safety issues, contract administration, OMWESB minority contracting/workforce plans and general administration. Lina recognizes that GSI Builders has faced many of the same challenges experienced by MWESB contractors and recognizes that collective success to improve the inequities that exist, goes beyond percentages. One of Lina's greatest professional joys has been serving on the Virginia Garcia Memorial Foundation Board where she currently serves as the incoming Board Chair. Lina received her Bachelor of Science degree from the University of Oregon in 1974 and her family was one of the First Founding Families of the Virginia Garcia Memorial Health Center. Much of the groundwork was done in the 1970's and what began as a small clinic serving the local farmworker community all from a 3-car garage in Cornelius, Oregon, Virginia Garcia Health Clinic is now a 17-site Clinic providing culturally specific services to 52,000 low- income individuals in 62 languages. Lina maintains a high profile in the Latino community in Oregon and Arizona and she and Steve continue to actively support several Latino organizations in the local community. Lina has served on the Boards of numerous Latino non-profit organizations and has been recognized as a Leader by many of those organizations. Currently, Lina sits on the LatinoBuilt Board which advocates for Latino Contractors in Oregon and the EngAGE Board which deals with Seniors and building communities for all ages through the creative arts. Lina also sits on the Hispanic Women's Corporation Board (HWC) a national organization that sponsors a one-day conference designed to empower Latinas of all ages and in various professional fields. Lina believes that arts build emotional resilience and coping skills and strengthens our sense of identity and community. Lina is a huge supporter of the Arts and is a practicing plein-aire painter. She Chaired the Regional Arts & Culture Council (RACC) and was responsible for the adoption of the Agency's First Equity Plan. She also spearheaded the art gift exchange of "Hermano Mago," an iron sculpture housed in the lobby of Portland5 Centers for the Arts. This piece of art was donated (and transported) to the City of Portland by its Sister City of Guadalajara, Jalisco, Mexico. She remains committed to staying healthy by practicing Pilates. She loves to travel and explore towns, villages, old colonial haciendas and world heritage sites throughout Mexico and Espana.
