Jasmine earned her Bachelor of Architecture from the Ohio State University and her Master of Architecture from Virginia Tech. Originally from the suburbs of Northern Virginia, her love for the built environment and equitable development are shaped by her experiences traveling and observing the wide scope of experiences different people are offered solely based on their economic and geographical status. She hopes to continue providing a wide scope of positive, healthy and sustainable built environments for everyone through thoughtful and collaborative design processes.
Laura Graden-Cotts, AIA, LEED AP BD+C
Laura has a deep love of the endless challenges that come with the real-world implementation of the built environment, and thrives on the practical and technical questions that really make a building work. She has unique experience as an architect, serving her formative years as a full-time owner’s on-site representative for both large and small construction projects, and relishes seeing the design on paper become a reality. As a result, she has a unique talent for communicating with owners, designers and contractors alike, as well as an understanding of complex contractual roles required to bring intricate projects to life.
Laura earned her Bachelor of Science in Architecture and Master of Architecture degrees from University of Idaho. Her previous experience includes healthcare, biotechnology, and research and development facilities for higher education, and retail facilities.
Mary Wyllie, AIA
Mary has over 20 years of diverse experience in architecture which includes transit, hospitality, retail, office, tenant build-out, renovations and mixed use, and in sustainable/energy saving design. In the 10 years she has been with HEWITT, she has worked as the project manager and project architect on Northgate Station, Judkins Park Station and Downtown Redmond Link Extension early work phase. She also represented Sound Transit as a part of the DBPM team for the final design phase of Downtown Redmond Link Extension. Mary brings that extra level of care and attention to detail that translates into a successful project for the entire team and one that responds to the needs of individual communities.
Active in AIA Seattle, Mary served as co-chair for Women in Design and the AIA Transportation Task Force. She served on committees to plan and host the AIA Women’s Leadership Summit in Seattle and plan a Women in Design installment for the Design in Public’s Design Festival. Mary moved to Seattle to experience and enjoy all that the Pacific Northwest has to offer. On any given day, you might find her out on a long run or discovering a new wine.
Morgan Hougland, LEED AP
Morgan has contributed his planning and design skills to several of Sound Transit’s initial future light rail station planning efforts and significantly contributed to several light rail station designs. He is currently providing design services during construction for the Judkins Park Station and the Mercer Island Station on the beginning segment of Sound Transit’s Eastlink expansion. He is also currently providing design guidance on the City of Seattle’s Madison Street Bus Rapid Transit – RapidRide G Line, and the RapidRide J Line through Roosevelt, Eastlake, and Downtown.
Morgan earned his Bachelor of Arts in Architecture and Master of Architecture degrees from Washington University in St. Louis. He spent a summer studying and building at the Yestermorrow Design/Build School in Waitsfield, Vermont. He has previous experience designing fire stations and fire training facilities, cultural museums and environmental learning centers, and worked on the restoration of historical multi-story manufacturing buildings into residential lofts, art galleries, and restaurants. This diverse work experience contributes to his drive to design resilient, sustainable facilities, with a focus on the user’s experience of the spaces, and a deft integration of the project into the urban fabric of the site and its surrounding neighborhoods.
Sean Sullivan, AIA
Sean joined HEWITT fourteen years ago with a background in hospitality and adaptive reuse and the goal to practice urban architecture and placemaking. During his early years at HEWITT, Sean enjoyed collaborations with developers and the contributions that he and the HEWITT team made to the fabric of Seattle’s Belltown neighborhood. The Northgate Station Parking Garage was Sean’s first transportation project, where he was impressed by the client’s focus on the user’s experience and grew a fondness for the inherent public nature of transportation architecture. Sean has since dedicated the last seven years to expanding the region’s transportation projects and is privileged to continue this journey with HEWITT colleagues, project partners and transportation agencies.
Sean earned his Bachelor of Environmental Design from Miami University and after earning his Master of Architecture from Washington University spent a decade working in St. Louis where he developed an appreciation for the sense of place and history embedded in existing buildings. Sean’s appreciation of the existing built environment combined with his private development project experience have fostered sensibilities useful to the planning phases of Sound Transit’s Lynnwood Link, West Seattle and Ballard Link extension projects. Sean’s twenty-five years of experience in the industry allows him to shepherd the design process from concept through construction for the Redmond Transit Center where he and the design build team are working collectively with client and stakeholders to create a unique place that benefits the community while supporting the region’s transportation network.
