MARCH 2020:  How PBWS is Addressing COVID-19


We at PBWS have been carefully following the development of the public health emergency due to the coronavirus.  We are regularly checking the Los Angeles County Department of Public Health website for updated information.


The health and safety of our team, clients, and community is of highest importance to us, so we are following State and County orders to stay inside personal residences, and immediately limiting all movement outside of the home beyond what is absolutely necessary to take care of essential needs.


To ensure that our clients are still well-served while our staff are out of the office, we have expanded our remote work capabilities.  Over the last several years, we have been making greater and greater use of available remote work technologies.  In light of the current public health emergency, we have further developed our team’s capacity to work from home through additional training and hardware as needed.  You may still reach us by calling our regular office phone number and by email.  We are also making use of audio/video conferencing and screen-sharing. We continue to work with all of our clients to navigate this extraordinary time.


We are keeping up to date with the Los Angeles County Department of Public Health recommendations and will communicate any changes in the way we are operating through this website and direct communication with our clients.  If you have questions about our policies and procedures related to the coronavirus, please contact one of our Partners.

DECEMBER 2019: PBWS Architects is delighted to endow the PBWS Architects/Harlan Pedersen Scholarship for Pasadena Community College Architectural Education. The intent of the scholarship is twofold. First, to recognize and reward student success in the study of architecture as a steppingstone to a professional career, and second, to encourage cultural awareness of architecture among all students through the qualifying criteria of enrollment in at least one class in the Area of Study in Architecture.


We are also grateful for the opportunity, in the naming of the scholarship, to honor the founder of PBWS Architects in his 95th year, Harlan Pedersen. Harlan mentored many aspiring architects and established a tone of warm humanity and wisdom that endures today through his successors. The firm was founded as Dinger and Pedersen Architects AIA in Temple City and soon moved to Pasadena in 1954. PBWS continues to call Pasadena its home with offices near Old Town Pasadena.


The initial endowment is funded by donations from PBWS Architects, LLP and Greg and Nora Sun.

The Center’s design aesthetic is derived from the surrounding context of the Hillsides campus’ institutional buildings and on-site residential cottages. While large in overall square footage, the facility’s interior breaks down volumes to provide a more comfortable, home-like feel.

JULY 2018:  Gregory Sun Celebrates 40 Years With PBWS! On a sizzling summer day, the staff of PBWS came together to celebrate Greg Sun’s 40 years of dedicated service to the firm.  Upon graduation from Cal Poly Pomona, where he earned both a Bachelor of Science in Architecture degree and a Master of Architecture degree, Greg spent one year with another practice before he came to know the principals of PBWS Architects (which at the time was known as Pedersen Wesley Architects).  He was seeking a place where he could make a significant and lasting contribution…and has he ever!  Joining the firm in 1978, Greg quickly displayed his aptitude for addressing technical issues.  Just five years later, Greg was elevated to Principal.  Today, Greg is Managing Partner of the firm and projects under his direction include municipal, educational, commercial, childcare, recreational, housing, and healthcare facilities.  Our thanks to Greg for his unwavering allegiance to PBWS, his passion for design, his continued mentorship of our younger staff, and his mad golf skills!

JUNE 2018: Kirstyn Bonneau led a continuing education workshop entitled “Microenvironment Design for Teachers” for a local private TK-8 school. The workshop was divided into two parts: 1) why space design is important for learning outcomes and 2) basics of environmental design. The first portion presented current research on the effects of daylighting, green view, and other environmental factors which impact student learning. Then, an overview of design process in general and major elements of environmental design specifically were discussed.

FEBRUARY 2018:  PBWS Architects recently completed a campuswide ADA Transition Plan assignment to remove door hardware barriers at College of the Canyons, a project involving over 25 buildings.  We were so pleased to receive this email from our client:


“Thank you so much for doing such an outstanding job. Your knowledge and expertise on this as well as other ADA project experience was clearly reflected in each and every response, which very much enlightened those that haven’t been intimately involved with this process/project. Well done!


Even though you may not think so, your participation was priceless to the District. It really, really was. It confirmed what I’ve believed for a while and that is that we absolutely have the best team possible handling our accessibility projects, hands-down. And we know it. Thanks again.”

JUNE 2017: Wade Frazier, a Partner of PBWS and member of the Pasadena Complete Streets Coalition, recently conducted an 8-mile bike tour of significant architecture in Pasadena and South Pasadena.

FEBRUARY 2017: The partners of PBWS Architects announce that Fred Wesley has retired from the firm, but will remain active as Partner Emeritus.


Fred has been a pivotal leader of the firm for 45 years, establishing and upholding its core values and seeing it through changes in the economy without compromising on services or staffing.


Joining PBWS in 1971, Fred was still an architecture student at USC.  He became a full-time employee upon his graduation in 1974.


He worked on one of the firm's construction sites as an apprentice carpenter, and quickly became involved in the firm's design-build practice. An interest in understanding the entire design and construction process led Fred to an increasing role in management, ultimately resulting in his service as Managing Principal from 1993 through 2014.


Fred was President of the AIA Pasadena & Foothill Chapter in 2003, has served on the Sierra Madre Planning Commission, and is past Board Chair of the Frostig Center in Pasadena.
