Meet Your Team

Jeff Jeannette

Principal, Lead Architect

Jeff realized his interest in architecture around age 8. At 11, he helped build his family cabin and in high school framed homes, gaining a balanced understanding of connections, details, and how homes are built. He and his wife built their own home in Long Beach, playing role of the homeowner, just like you. These experiences make him a creative and well-rounded architect in design and construction detailing as well as providing knowledge in preparing our clients for what’s to come. In 2000 he started his architectural firm with a passion to design beautiful homes that function and flow perfectly, reducing the stress of the entire experience.

Why am I an architect?
I enjoy listening to a family’s needs and designing homes that fit their lifestyle now, and for years to come. Transforming houses into homes, puts smiles on our clients faces, and mine.

Guess what?
When I’m not designing, I enjoy flying remote control airplanes (yeah, I’m a bit geeky that way) and playing ping pong with my two boys, visiting museums, home tours and date nights with my wife.

Jeff’s is a graduate of the University of Arizona, 1994 and an alumnus of the Goldman Sachs 10,000 Small Business Program. He’s designed over 700 homes and holds memberships with the AIA, USGBC, NCARB, and has been involved with the Long Beach Heritage Historic Home Awards for multiple years. He’s licensed in California, Nevada and Texas, a Certified Green Building Professional with Build it Green, and has sat on the board / advisory panel for The Reuse People of America since 2007.

Roberta Jeannette

Architect / Advisor

Though Roberta has been involved since Jeannette Architects inception, her active role in the office started in January 2014. She offers guidance in staff management, hiring, accounting, and community outreach. Her previous experience in residential architecture lends itself to understanding the process and needs of the staff, as well as the clients.

Why am I an architect?

My background in visual art as well as my ability to analyze information led me to pursue an architecture career. I believe designing a successful, beautiful home requires a blend of technical skills with creative, artistic expression.

Guess what?

Jeff and our two teenage boys keep me on my toes, but when I’m not coordinating their lives I’m a news junkie and I like to read (with a book-a-week-challenge), do Pilates (I swear there’s abs in there somewhere) and would love to find a job that pays me to watch television and eat popcorn.

Roberta received her BArch from the University of Arizona in 1993 and became a California licensed architect in 2006. She serves on several local organization’s boards, including the Navy Memorial Heritage Association and is the treasurer on the Beach Cities Youth Lacrosse Board.

Stefanie Häring

Architect, Project Manager, LEED Green Associate

Stefanie brings 20 years of architectural experience, and creative problem-solving skills. She has a solid base of knowledge encompassing all phases of building design. Her career has exposed her to a wide range of building and construction types, residential to laboratory buildings, theatres, hotels and high rises. She has led seasoned teams, as well as young architects, and enjoys the challenge of integrating different disciplines into a building while preserving the original design intent.

Why are you in the architectural profession?

Stefanie couldn’t decide whether to study sports, psychology, mathematics, any kind of engineering or simply deliver mail! She eventually figured architecture was the prefect profession to encompass her many talents and interests.

Guess what?

Since architecture does fall short of physical exercise you might find Stefanie in her free time in the pool, playing beach volleyball, hiking or on the dance floor. Since she believes the greatest challenge of our times is our transitioning into a new climate era, she is also member of Citizen’s Climate Lobby lobbying congress to put a price on carbon.

Stefanie is a graduate of Universität Stuttgart, Germany, but also spent one year of her graduate studies at Arizona State University. There she fell in love with this country, it’s natural beauty and the everlasting sunshine. She is a licensed architect in California, as well as a LEED Green Associate.

Why am I an architect?

From what I can remember as a child, art was something I enjoyed. In my middle school metal shop class, I was introduced to architecture. One of my shop projects was to build a wood frame model of his house. That experience led me into the path of pursuing a career in architecture.
I see Architecture as the building and everything around it. I’ve had the opportunity to design furniture, lighting, temporary sculpture, and landscape plans.

Guess What?

I have a passion for travel, classic cars and scooters. I got the traveling bug in college when my summer art class went to Paris. When traveling to the different countries, I’d bring back something artistic to remind me of my visit there. My family tries to travel abroad at least once a year.
On my off time, I like to work on his classic cars and Italian scooters. I like working with my hands and try to understand how things function.

Mark Kamish

Job Captain

Mark is either more or less serious than he looks, we can’t decide. As an LA native, it was only natural that he got his Master of Architecture degree from University of California, Los Angeles.

Javier Sevenello

Architectural Designer

Growing up in a City like Los Angeles, Javier had the opportunity to look at buildings in a different way. One of the fondest memories include driving past Downtown with his parents and being starstruck by the enamored view of skyscrapers in the heart of his City. How can something so tall stand so perfectly still? Javier’s curiosity grew from interest to passion for the arts of building and form. He pursued his schooling and career in the field of architecture.

Knowing one can make a difference is anyone’s daily life is what truly makes this profession rewardable. Traveling to Italy twice has proven architecture will live on for a long time. Watching the emotions from the tourists as they walked through places that have been there for such a long time is remarkable because those buildings are still making an impact on today’s architecture. It’s about thinking for the future and leaving a stamp for his family and for the world, letting them know that he has made a difference.

Guess what?

Although I’m inspired by the architecture that surrounds us, I love the great outdoors. Anywhere there’s wind, landscape, and a view sounds like a new adventure waiting to happen. These types of places relax me and helps get through the daily thing we call life; It’s therapeutic.

Javier attended NewSchool of Architecture and Design in San Diego and graduated with a bachelor’s degree in 2020. He is currently pursuing for his LEED certification and progressively working towards licensure.
