Meet Your Team – Jeannette Architects

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 & Office Manager

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.

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.

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.

George Jang

Architectural Designer

George has always found joy in immersing himself in cartoons and video games—a pastime his mother might say lasts just a bit too long. Yet, for George, these experiences have become more than just entertainment; they are a gateway to connecting with others and exploring the artistry of the creative world. The digital medium serves as his catalyst for meaningful conversations with friends, both old and new, sparking discussions about the design of buildings, homes, and the imaginative landscapes experienced through fantasy books, anime, cartoons, movies, and video
games.

This passion for digital storytelling and visual artistry is what led George to architecture. He was captivated by the interplay between the tangible world of physical structures and the boundless possibilities of the digital realm. His journey took him to Cal Poly Pomona, where he earned a professional bachelor’s degree in architecture, equipping him to bring his love for design, creativity, and connection to life in both the physical and digital spaces.

Guess what?

When George isn’t busy working or cramming for the Architect Registration Examination, you’ll likely find him pedaling through town or sweating it out with local fitness groups. Whether he’s attempting to keep up at a community run, striking a wobbly tree pose at yoga in the park, or maybe someday braving a marathon, George is all in for the fun (and the struggle). If you see him, don’t be shy—wave, cheer, or come say hi! He might look like he’s questioning his life choices, but trust us, he’s having a blast.

Jill Brubaker

Office Manager

I’ve had the privilege of serving alongside the Jeannettes in various community capacities over the years, so when I found out there was an opportunity to join the team and help support day-to-day operations, I was honored to be brought into the JA family!

Guess what?

My family and I have lived on multiple continents! So, I really enjoy learning about new cultures and traditions. I also love how humor can connect people and discovered far too late in life the value of being able to laugh at myself! I’m also a fan of science fiction, especially in movies; anything that makes you think about time and space in non-linear ways is exciting to me.

Education / Affiliations

It sometimes surprises people to find out that I am much more of an introvert, because I have always pursued studies and experiences that have me interacting with people. My undergrad was in communications and I received my master’s degree in ethics, so working with and for principled people of high integrity is a must for me!
