Firm Profile

Directed by Principals Kava Massih, Jerry Mastora and J. Conner plus Associates Mark Schlientz, and Mary Young-Williams, Kava Massih Architects has been a driving force behind a wide range of innovative architectural designs in the Bay Area since its founding in 1996. The firm does not focus exclusively on one building type but applies the totality of the staff’s collective experience to many different kinds of projects. The firm has completed a wide variety of project types including public institutions, commercial buildings, restaurants, market rate and affordable housing, and highly specialized medical facilities. This studied flexibility is an essential skill when designing for challenging urban sites or where existing structures must be incorporated into a rehabilitation project or preserved.

Like much new construction in the Bay Area, many KMA projects are located in former industrial areas that are now transitioning into vibrant mixed-used and residential districts. The Sierra—an eleven-story, 500,000 sq ft mixed-use development comprised of ground floor retail, 227 loft-style condominium units, a recreational facility, and three levels of parking, occupying an entire city block—is an excellent example of a project that incorporates industrial scale and detailing with residential warmth.

The firm has also focused on working with many non-profit groups and educational institutions. Principal Kava Massih often donates additional services and time to help non-profits secure financing through grants and fundraising efforts. We are adept at expediting the approval process by investigating and addressing community concerns early in the design process. This kind of commitment to clients and the community has helped the firm establish long-term working relationships with both private clients and public institutions.

The firm organization is characterized by an open and collaborative spirit that extends to its clients and communities. Our long list of repeat clients is testament to our creativity, dedication and flexibility.  We have earned a reputation as a firm capable of delivering innovative design on time and on budget. Our professional services include feasibility studies, programming, space planning, architecture, interior architecture, construction documentation and administration through occupancy. 

We believe in a holistic approach to design which allows a balance between the current needs of our clients and a respect for the future needs of the planet. We fully understand that sustainable development needs to be an integrated process involving all members of the project team. Commitment to a sustainable process leads to a high quality product with minimal impact on the environment and a solid return on investment.

Kava Massih - principal

Since founding Kava Massih Architects in 1996, Kava has guided its steady growth, built its strong reputation, and garnered the respect of many repeat clients. Kava brings to all projects clear, innovative, and inspiring designs. He leads the firm’s design initiatives and his personal involvement in each phase results in a consistent quality for all projects.

In an article published in Diablo Magazine, Kava was described as a “visionary” who is “on the frontier of East Bay architecture…reshaping our world…Kava Massih’s buildings stand out.” Under his leadership, the firm has received numerous awards and jury invitations, including recognition as an “Emerging Talent Firm” by the California Council of the American Institute of Architects (AIA).

Kava’s philosophy is to approach each project without preconceived ideas in order to find the best design solution for that project. His environmentalist views and dedication to public service are also reflected in the values of the firm. Through his service as a member of the Emeryville Planning Commission, he brings an in-depth understanding of how cities approach the planning and approval process.

Kava works extensively with project stakeholders, keeping them interested and involved, ensuring that their concerns are addressed, and integrating their vision for the project into the design. He is regarded as a master consensus builder, able to satisfy the needs of various constituencies. Through his ability to listen and communicate effectively with multiple stakeholders, he ensures that all participants are on board with a design.

Jerry Mastora - principal

As a founding partner of Kava Massih Architects in 1996, Jerry has been directly involved with many of the firm’s significant projects and long term clients. With over 25 years of architectural experience, Jerry has effectively directed complex, large-scale projects, coordinating input from a wide range of stakeholders in developing architectural programs that set the course to reach client’s goals. He has extensive experience in feasibility studies, programming, and master planning, with a proven ability to balance client objectives with project budgets. Jerry is also skilled in construction technology and directing construction administration for complex institutional projects.

Jerry has designed and managed the projects of several prominent Bay Area hospitals, including UC San Francisco, Saint Francis Memorial Hospital, Alta Bates Summit Medical Center, Alameda County Medical Center, and Children’s Hospital Oakland. One of his more notable projects was the re-design of the Emergency Department for the Summit Campus of Alta Bates Summit Medical Center, including 25 treatment and resuscitation rooms. The project included careful construction staging so that emergency services could continue without interruption. He also designed the Health Sciences Building for Children’s Hospital Oakland. Because the building houses a sophisticated diagnostic tool known as a Ferritometer, it had to meet sensitive magnetic and vibration requirements, while also being cost effective, child friendly, and responsive to the historic context of the hospital’s Research Institute campus.

J. Jarrell Conner - principal

Since joining Kava Massih Architects in 2000, J. has been an indispensable asset to the firm. In his over eighteen years of architectural experience J. has successfully overseen numerous projects through all stages of development—from contributing to the initial design efforts to managing the project through completion and close-out.

J's expertise spans a wide variety of project types including market-rate and affordable housing, restaurants, tenant improvements, new construction, renovations, commercial, retail, and institutional. He is especially well-versed in project management and construction administration. He has successfully guided many projects through the entitlement process, skillfully negotiating with user groups, neighborhood groups, consultants, and regulatory agencies in order to gain consensus and keep these projects on schedule. He is flexible in his approach, easily accessible to clients, and an excellent communicator with the entire project team, insuring projects move forward successfully.

J received a Bachelor in Architecture from the University of Virginia and a Master of Architecture from University of California, Berkeley. He is a LEED accredited professional.

He is currently overseeing a large market rate housing project in the SOMA neighborhood of San Francisco.

Mark Schlientz - senior associate

After completing a master’s degree program at the University of Texas in Austin in 1997, Mark returned to the Bay Area where he joined the newly formed firm of Kava Massih Architects. In his over 16 years with the firm, Mark has worked on a wide range of project types, including several institutional projects, as well as adaptive reuse, commercial, multi-family housing and healthcare. He played a key role in planning and designing of several large projects including, Rosa Parks Elementary School in Berkeley, the Bentley School in Lafayette, and the Contra Costa County District Attorney’s headquarters in Martinez, taking these projects from early stage programming through construction. Mark excels in project team communication and maintains positive on-going relationships with clients, consultants and contractors through project completion and beyond. He was invited to become an Associate of the firm in 2003 and a Senior Associate in 2010.

Mark is currently overseeing the design of a 472 unit mixed-use development in Los Angeles.

Mary Young-Williams - associate

Mary’s architectural experience spans a wide range of project types including healthcare, institutional, commercial, education, and multi-family housing. She is involved in every aspect of the architectural process from early planning/schematic design to code review to construction and client move-in. Mary has been especially involved in tenant improvements, coordinating with the building owner, the tenant, and the contractor to arrive at the final product. Having experience with design-build, she has worked closely with both the owner and the contractor to arrive at the final product. She also specializes in all aspects of interior architecture—from space planning and interior design to the selection of color palettes and furniture. Since joining the firm in 2008 she has been an invaluable team member. Mary was invited to become an associate in June 2012.
