Team OBI
Severin Oliver - Principal
I am a Bay Area native, born and raised in Berkeley. Being outside and working with my hands drew me to building since I was a child. I have always been drawn to the details of building, and I enjoy every aspect of construction. Specializing in stair building and finish carpentry has taught me to look at both the big picture as well as the finer details in the building process. Now, as the principal of Oliver Builders, my goal is to make the whole experience as transparent and collaborative as possible for everyone involved.
I love getting to know our clients and developing a warm and trusting relationship with them. I take great pride in having not only assembled a united team of caring people who understand the importance of the honest and open relationships we build with our clients, architects, and other team members who also embrace the attention to detail that Oliver Builders has become known for.
In my free time, you may find me mountain biking in Marin County, or hiking and spending time with my family. My wife, daughter, and son are my pride and joy!
William Reuvekamp - Production Manager
I grew up in the world of construction. As a third-generation home builder, I started my career with my father building custom homes in the Bay Area. After seven years of working in residential construction as a project engineer, project manager, and estimator, I made the switch over to commercial where I was a full-time estimator working on public works, pharma, and food tech projects. In 2022, I could no longer ignore the fact that I wanted to build beautiful homes again and found the perfect opportunity with Oliver Builders. Throughout my time in construction, I have found a passion for estimating, scheduling, and planning the perfect project. In my free time, I enjoy spending time with my wife, two children, and dogs and passionately cheering on my favorite sports teams: Giants, Steelers, and Arsenal.
Hector Tavera - Project Manager
I was born and raised in Caracas, Venezuela. I moved to the Bay Area in 2015 to pursue graduate studies in Energy Systems Management, which I earned in 2020 from The University of San Francisco. I have continued exploring construction work especially in the electrical realm since my arrival, which led me to obtain an Electrical Contractor License in 2023 before joining Oliver Builders. A conversation with Severin, which I have known for over 20 years he happens to be my brother-in-law, fueled the spark to continue Oliver Builders legacy of professionalism, integrity, and honesty while delivering an incredible final product. Outside oliver Builders my family, nature, and sports round up my interests.
Adina Nystrom - Bookkeeper
Adina is the new bookkeeper for Oliver Builders. Adina brings a level of experience, detail, and commitment that is benefiting Oliver Builders in many ways. Our website is under construction and will be updated shortly with this important information about our team member!
Juan Velasco
I have 20+ years of working in the construction industry as a lead carpenter and project Foreman. I am passionate about building novel projects, creating world-class connections with clients, and ensuring my work is at the highest level. During my tenure, I have endured many challenges, but what motivates me is the smile on the faces of others when their vision becomes tangible. I look forward to continuing to grow my skill set, teach others and build beautiful projects with Oliver Builders!
Jeff Reuvekamp
I was born and raised in Oakland and am a second-generation contractor. Both of my sons have followed me into the construction business. I have always wanted to be involved in construction and nothing makes me happier than being on a job site.
I graduated from Cal and went to work for a commercial contractor. I then opened my own business building custom homes which I operated for 25 years. Since that time I have worked as a Superintendent on high-end luxury residences.
I take great pride in my ability to keep things on schedule, solve problems creatively, and have a great working relationship with everyone on the job – my fellow employees, clients, sub-contractors, and other professionals. I am a perfectionist and make sure that the finished product reflects that trait.
In my free time, you’ll find me barbecuing, spending time in Truckee, or enjoying time with my family – especially my two grandchildren and my black Lab.
Nicholas Pessah
I was born in Burlingame and have stayed in the Bay Area for most of my life. After completing college at Arizona State with a bachelor’s degree in business and minor in communications, I jumped into the world of construction and real estate. After working in the field for several years I went out and got my General Contractors license and started doing luxury home remodels as a superintendent. I have been in the field coming up on 15 years. I take great pride in my craftsmanship, having open communication with our clients, problem solving and coordinating with our subcontractors. After moving to the east bay I joined Oliver Builders because of their honesty with clients, their work ethic, and always choosing to do the right thing. In my free time I like to stay healthy and live an active life style, spending time with family, and traveling. I look forward to working with you and building a house you can call your home.
Joel Chala
I was born and raised in Cuba. After going to college and getting a teaching credential in Havana, I taught technical drawing and wood technology for ten years to deaf middle and elementary school children. Since immigrating to Berkeley in 2001, I have been working in the construction field in different areas: as a builder, estimator and project manager. I got my license as a cabinet maker before joining the OBI family in 2014. I've known Severin for over twenty years, so the OBI team feels like extended family to me. When I'm not at work, you will find me mountain biking, hiking with friends, or traveling to lacrosse games with my wife and daughter.
Haley Reuvekamp
I am a certified Montessori pre-school teacher. Once my first child was born, I decided to become a nanny so I could stay home with him and continue my love of teaching with the other children I cared for. As they became older, I decided to switch gears and work in construction. My father is a carpenter and I grew up around jobsites so the change felt very natural for me. I also have a degree in music and am a classically trained singer. In my free time, you can find me spending time with my husband and children and enjoying baking and crafting.
Tina Meeks
I have a background in Team Management and Event Coordinating, which helps me organize and bring people together. I also have a degree in communications which helps me make effective connections with people. When I’m not in the office, you'll find me hiking, spending quality time with loved ones, and writing poetry. I am stoked to have joined the OBI team!
Daisie Cole
My work background is in the tech industry as an engineering productivity software engineer. I worked on tools and infrastructure that increased speed, ease, and quality for developers, and that skillset is lending itself well to my contributions here at Oliver Builders as Project Finance & Efficiency Lead. We're innovating the age-old processes and conditions of the construction industry, and in doing so creating a more efficient and transparent experience for our clients. I've lived in the Bay Area since 2006; I may not have been born here but I certainly feel like this is my home. My husband, sons, and I enjoy checking out new hiking trails and being foodies at new places. I love dancing and crafting, and you'll definitely find me locating the nearest dog in my vicinity to play with and pet!
Mark Olivier
I have a 30-year work history in construction under my belt, so I know what a disruptive process construction can be to homeowners. As such, I always try to empathize with them and listen to their needs in order to facilitate the project’s success. My ability to get along well with my co-workers, to continually learn new aspects of building, and to understand the architectural plans are some of the aspects I enjoy in my work.
I also have a background in Traditional Chinese Medicine, and enjoy cooking, being with my dogs and bird watching. I’m also an artist, and am mainly in my studio working on projects when I’m not at Oliver Builders. If you’ve ever driven down Colusa Avenue in Berkeley, and wondered about the yard sculpture art, that’s my house!
