Eric Stovner | President
First inspired at the age of 3 when his dad walked him by a construction site with jib crane and steel frameworks, Eric played with his Legos and building blocks, and in high school was mentored by Todd Wales with four years of drafting and housing design and William Bell with architecture. Eric was welcomed by George Hasslein into the stellar Architectural Engineering program at Cal Poly San Luis Obispo, learning from many fine professors, including Jake Feldman, Sat Rihal, Clay Pharoah, David Hatcher, Robert Liu, and Celina Penalba. Eric interned in the Riverside, CA office of Johnson & Nielsen, learning from Per Ron, Don Irving, Clarence Behling and Rick Bird. Upon graduating from the program in four years in 1987, Eric worked in New York, NY with great companies Leslie E. Robertson Associates – mentored by William Faschan, Monica Svojsik and Hal Roet, Robert Silman Associates – mentored by Bob Silman, Marie Ennis and Donald Friedman, and Thornton Tomasetti – mentored by Tom Scarangello, Peter Rottas, Charlie Thornton, Dan Cuoco, Manny Velivasakis, Dave Peraza, Aine Brazil, Kirk Mettam and Richard Tomasetti. With Thornton Tomasetti, Eric returned to California, mentored by John Coil, Stephanie Welsh, Ed Kasparek and Jim Ebrahim, and also worked with Miyamoto, mentored by Chris Smith. Eric has had the blessed fortune of always working in a profession that he loves. Eric started his company Critical Structures in the spring of 2009 with supportive prayers, emotional support, generosity and well wishes from so many family, friends, clients and one very special angel — JP — in particular. In the winter of 2009, Eric acquired Breiholz Qazi Engineering, a company established in 1973 by David Breiholz. It has been fantastic to work closely with Dave and to continue to serve his clients. Eric’s current phase is to build on the strong foundation of a great group of people and continue working with great clients and friends in this profession of endless possiblities.
Stephen Fong | Sr. Project Manager
Originally interested in architecture and design at a young age, Stephen changed his focus to the more technical side of buildings after taking AP physics at Berkeley High School with teacher Richard White, who inspired him to always think creatively and introduced him statics and dynamics and the foundation of what would later become Stephen’s career. Following high school, he attended the Henry Samueli School of Engineering at UCLA for 3 ½ years and graduated with a BS in civil engineering with a structural emphasis. Stephen’s first job out of university was with Stuart Engineering, a civil engineering firm located in San Diego. After several months with Stuart Engineering, he was hired as a structural designer at Wynn Engineering, a structural and civil engineering firm. Stephen spent several years working at Wynn Engineering developing his skills in custom home design and various other small scale residential and commercial projects. In addition, whenever the civil engineering department was overloaded, he took the overflow and provided design for many grading plans. After working in San Diego, Stephen moved to New York, NY and took a job with Goldstein Associates Consulting Engineers, where he worked for the following 3 years, starting as a Structural Engineer and becoming Project Engineer shortly thereafter. During his time in New York City, Stephen was the project manager for several high rise residential and commercial buildings, as well as the restoration and rehabilitation of a prominent New York City landmark apartment building. In 2010, Stephen returned to California and began work with Breiholz Qazi Engineering in Lomita, CA, which later became Critical Structures. He has continued his work with Critical Structures, always striving to produce creative designs while keeping in mind efficiency and cost effectiveness. Stephen is now located in Berkeley, CA, his hometown. He is proud to be a part of the Critical Structures team.

Mary Caldera | Senior Drafter
If you are reading this bio, congratulations, you have achieved a Level 5 Security Clearance from CSI. Once upon a time, Mary Caldera took a History of Architecture course for fun. After changing her major to Architecture, she received her Certificate and AA in Architecture from El Camino Community College. Near the end of her first CAD course she saw a flyer for a drafting position in the school lab and started working for Breiholz Qazi Engineering, Inc. in the fall of 2005 and has stayed with the company through its transition to Critical Structures, Inc. Mary enjoys translating architectural info for our structural plans, walking catwalks (the rigging kind), historic building visits, getting plans approved for permit and coffee breaks. Outside of work she can be found gardening, drawing or acting like she’s 12 at Disneyland.
Rosa Ocegueda | Project Engineer
I grew up across the street from the construction site of the Los Angeles County + USC hospital. For 8 years that was the first thing I saw as I stepped foot outside my house and it deeply influenced my interest in buildings. I considered studying architecture until I took physics in high school. From building rockets to calculating exactly where a ball would land, I knew I wanted to continue learning physics. I went to UC San Diego and studied Structural Engineering; a combination of physics, buildings, and a little bit of architecture. My favorite (and most challenging) courses involved design. I loved the fact that we created models of the projects we designed. This brought back my interest in architecture and resulted in a minor in Urban Studies and Planning where I focused on Urban Design / Built Environment. However, I believed this was not enough exposure to architecture and decided to look into architecture for graduate school. I received a Master of Science in Architectural Engineering from Cal Poly San Luis Obispo advancing my studies in both structural engineering and architecture. I look forward to starting my career as a structural designer.
Jaime Grabinski | Structural Designer
As a kid, I used to tell my parents that one day I would design and build them a house to thank them for what they’ve done for me; so naturally I grew up hoping to become an Architect.
While attending the Long Beach Poly High School P.A.C.E. honors program, I took a liking to the math and physics courses and my teachers recommended I go into engineering. After doing some of my own research, I found that I could become a civil engineer and still accomplish my childhood goals.
I began studying at California State University, Long Beach, striving to obtain my B.S.C.E. As an undergraduate, I joined the Earthquake Engineering Research Institute’s “Seismic Competition” team. We had to design and build a high-rise model out of balsawood and test it on a shake table against teams from around the world. Although we didn’t win, we did receive an award for “Best Seismic Performance” due to having almost no damages to our building; which we took as a huge success. Being part of this team solidified my desire to emphasize my focus on Structural Engineering while pursuing my master’s degree.
I continued at CSULB for my M.S.S.E. and during my first semester, I became President of the CSULB chapter of Chi Epsilon and I also began my research on “structural health monitoring” for my thesis. While nearing the end of my graduate career, I joined the Critical Structures team in October 2018. Moving forward I would like to make a larger impact on the city of Long Beach, the surrounding areas, and achieve the childhood promise I made to my parents.
Away from work I enjoy bowling in tournaments and leagues with my parents, playing video games, and going to theme parks with friends.
Dhamar Lopez | Structural Designer
From an early age, I always placed importance in my education and found myself inclined to the areas of STEM. I decided to pursue a career in Structural Engineering when I learned about the field of study and came to the realization that it was a profession that would continuously challenge my problem-solving abilities. It would also allow me to contribute towards the greater efforts of design and making of structural elements.
I obtained my Bachelor of Science at the University of California, San Diego, where I majored in Structural Engineering with an emphasis in Civil Structures. While spending my undergrad years in sunny San Diego, I interned as a design engineer for Sullaway Engineering. There I gained my first experience of the design engineering industry. After graduation, I moved back to my hometown in the Los Angeles area and held a project management role for a residential development company where I became exposed to all processes involved in the construction of luxury homes.
As a young engineer, I thrive on learning and developing my engineering intuition and I look forward to growing as a problem-solving professional at Critical Structures.
Brian Boger | Structural Designer
I am a driven and highly motivated engineer with a passion for problem-solving and structural engineering. I graduated from Iowa State University in 2021 with a Bachelor of Science degree in Civil Engineering. I am currently continuing my education by pursuing a Master of Science in Civil Engineering with an emphasis in structural engineering at Purdue University, West Lafayette.
Prior to pursuing higher education, I served in the military where I developed invaluable skills in leadership, discipline, and attention to detail that have served me well in my academic and professional endeavors.
With a keen eye for detail and a strong work ethic, I am committed to delivering results that exceed expectations. My passion for structural engineering stems from a lifelong interest in designing and building structures that can withstand the test of time.
In my free time, I enjoy staying active and exploring the great outdoors. Whether it’s hiking, climbing, canyoneering or surfing, I believe that physical activity is essential to maintaining a healthy mind and body.
