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 | Senior 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.
Andres Medina | Structural Designer
I grew up in the Wilmington/Long Beach Area knowing that I wanted to be some sort of scientist. So through my time in middle and high school I took time to explore those interests. In high school I joined the Solar Cup team which gave me great exposure to engineering concepts. The Metropolitan Water District’s Solar Cup is a large high school competition to promote water conservation and alternative energy use. I knew I wanted to be an engineer by the time I entered the Structural Engineering Department at the University of California, San Diego. At San Diego I became involved with the steel bridge competition and did some mentoring of my lowerclassmen peers. It was a tight knight community that developed my passion and dedication to the profession. I received a great education in the science and practice of Structural Engineering. I am currently pursuing a Master of Science degree in Structural Engineering at California State University, Long Beach. I am happy to now be a scientist dedicated to ensuring the safe performance and behavior of structures.
Rosa Ocegueda | Structural Designer
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.
Nirmal Kumawat | Structural Designer
Born in Indore (M.P.), India, I grew up watching my father’s work in the field of construction, which inherently made me inquisitive to understand how construction works and eventually got inclined to the technical side of it. I was in love with unfinished buildings, no less than an adventure spot did they look like to me! And thus my interest in civil engineering. To experience more extraordinary and advance mechanical modelling of genuine circumstances utilizing material science, physics and math were seemingly my choice of vocation. After my Bachelor’s, I worked as a project engineer to learn how to follow the designs provided by the engineers on field. I was actually getting everything executed but felt something missing. Mechanics! And thus happened my Master’s in Structural Engineering from California State University, Long Beach, where came the next opportunity. My work as a research assistant with Dr. Vesna Terzic for Applied Technical Council, National Science Foundation, and later during my Master’s, I was exposed to the practical use and power of coding languages and tools. All these projects also asked me to explore the world of technology, opening up the gates of connecting different fields with civil structural engineering to achieve best practical solutions.
