Sarah Yore-Van Oosterhout, Esq.
Founder; Managing Attorney & Advocacy Director
In 2008, Sarah completed her undergraduate studies at Calvin College. During her time there, she studied abroad, volunteered in Grand Rapids schools, tutored adults in GED programs, and worked with immigrant mothers at Cherry Street Medical Clinic, all the time putting to good use her Spanish language fluency and social work training. Sarah attended the Michigan State University College of Law, devoting herself to the study of immigration and public interest law. Following law school, Sarah, her husband, and young daughter moved to Mexico for a year where her husband completed his doctoral research.
In the fall of 2013, Sarah started work at the Diocese of Grand Rapids, Immigration Legal Services, serving as one of two full-time attorneys. She tackled a wide variety of family-based immigration cases and grew accustomed to handling a high volume caseload while still offering high-quality legal services. Sarah left the Diocese of Grand Rapids in December 2014 to work at a private firm, but soon discovered for-profit legal services were not what Holland immigrants needed. And so, she pioneered Lighthouse Immigrant Advocates.
Sarah also serves as the vice chair of the Immigration Law Section of the State Bar of Michigan and sits on the board of Out on the Lakeshore. When she's not working, Sarah gardens inside and outside, reads voraciously, hikes and backpacks, and paints botanical watercolors and acrylics (come see her mural at LIA's Holland office!).

Maggie Haveman-Gould
Program Director
Maggie has always had a passion for diversity, language, and culture, graduating in 2006 from Grand Valley State University with a Bachelor’s Degree in Spanish. She went on to work in the interpretation and translation field, coordinating interpreters to provide linguistic services for a variety of industries. She later moved on to recruiting interpreters in the US, UK, and all across The Americas for both common and rare languages based on the ever-changing needs of government services, immigration systems, school districts, hospitals, utility companies, and emergency services.
After leaving the industry to stay home with her three children, she also took on the challenging and rewarding role of becoming a foster parent for refugee children. In addition to her three biological children, she has ten “bonus lovies” who know her as Mamá Maggie, who have since been reunited with their biological families. LIA was her springboard to jump back into the working world, going from Volunteer, to Executive Assistant, to Human Resources Coordinator, and landing now as the Program Director since spring of 2023. She shares the load of leading LIA as one of three Co-Directors, replacing the traditional Executive Director structure to better allow for collaboration, shared executive duties, and to prevent the ever-prevalence of burnout in the non-profit field.
Known as the office’s “Queen of Organization”, you’ll find her streamlining as much as she can, helping to balance workloads, communication, and expanding on LIA’s welcoming atmosphere. Maggie has a deep love for social justice, and continues to focus on viewing the world through a trauma-informed lens. She is generally a crafty lady, and can create just about anything with yarn and a crochet hook. Her favorite evening plans are curling up on the couch with her husband while crocheting her latest project.husband while crocheting her latest project.

As the proud mother of four sons and wife to her husband John, Betsy joined the LIA in January of 2024. Educated in Holland and former student of Hope College, Betsy has had a wide variety of professional experiences, including bonus time as an expat in Guanajuato, Mexico.
