Simpson Gumpertz & Heger (SGH) congratulated their newest Associate Principals. According to SGH, these individuals possess the expertise and the dedication to SGH and its clients that enable the firm's sustained achievements.  
Craig Allender | Associate Principal
Craig Allender has a passion for helping clients address building enclosure waterproofing issues, with special interest in planning for the unique challenges caused by sea level rise in the San Francisco Bay Area. His recent presentations on the subject and activities with the Association of Climate Change Officers have been a catalyst for the conversation about how climate change affects coastal cities and how to identify strategies for flood resilience. Craig is experienced in investigating and designing major commercial, institutional, and residential buildings to address building enclosure waterproofing issues involving roofs, exterior walls, glazing systems, plaza areas, and below-grade spaces. He has consulted with architects, contractors, and building owners to analyze and repair water intrusion in existing buildings and to prevent these problems in new construction. Craig recently served on the Board of Directors of the Sealant Waterproofing & Restoration Institute.
Michael Mudlock | Associate Principal
By combining an understanding of structural behavior and analytical tools, knowledge of design standards, and meaningful onsite experience during construction and investigations, Mike Mudlock provides practical solutions to complex structural problems. He has investigated, analyzed, and designed various types of structures, including serving as a project manager for many nuclear design and investigation projects. His work has included structural design; evaluation of structures affected by alkali-silica reactivity; seismic soil-structure interaction analysis; onsite engineering support of new high-hazard concrete and steel structures; and evaluation and upgrade of reinforced concrete, concrete masonry, structural steel, wood-framed, and pre-engineered metal building structures, systems, and components. He actively serves as a leader on two Structural Engineering Institute (SEI) committees related to mitigation of disproportionate collapse potential – which are producing a new standard and technical guidance document – and on an American Nuclear Society (ANS) working group producing a new standard related to life extension of non-reactor nuclear facilities. 
Joseph Rogers | Associate Principal
Joseph Rogers collaborates with his clients to identify and focus on the critical elements required to maximize the service life of their structures. He specializes in building enclosure engineering, including design consulting for new construction, investigating performance problems, developing multidisciplinary rehabilitation programs, and designing and administering repairs for modern and historic structures. His work encompasses a wide range of building enclosure systems and materials, including roofing, modern and historic wall systems, below-grade waterproofing, and flooring. He leverages his broad building enclosure engineering experience to help clients with construction-related disputes by investigating building enclosure issues and serving as their expert witness. He also has a passion for giving back through education, and teaches the Investigation, Diagnosis, and Rehabilitation course for Johns Hopkins University’s Department of Civil Engineering.
Jonathan Stafford | Associate Principal
Jonathan Stafford specializes in applying his extensive knowledge of roofing and waterproofing to help clients solve challenging problems and design new systems that go beyond traditional water-related issues. He has applied his knowledge to the investigation and design of major commercial, institutional, and residential buildings to address waterproofing issues involving wall cladding, roofs, plaza decks, and below-grade spaces. He consults with architects, contractors, and building owners in designing the building enclosure for new projects, analyzing and repairing water intrusion problems, building modernization projects involving the addition of outdoor amenity spaces, and assessing construction defects for existing structures. He is an RCI Registered Roof Consultant and was a founding member and past President of the RCI Northern California Chapter.
Scott Tomlinson | Associate Principal
Scott Tomlinson excels at investigating the root causes of building enclosure failures, applying his expertise to analyze and understand existing conditions and develop creative approaches to solving his clients most challenging problems. He has broad experience investigating and designing building enclosure systems, and special expertise leading complex investigations. Scott has extensive experience investigating and providing litigation support related to building enclosure failures and material performance issues.
