Tim and Bob

A&M is guided by the firm's Principals and Co-Owners, Robert Clarke, PLA, ASLA and Timothy Williams, PE. Bob and Tim each have spent almost three decades dedicated to the built environment. Since taking ownership of A&M in 2015, they have assembled a talented and diverse team that honors the engineering roots of the company, while providing the disciplines that are essential to modern development.

Robert P. Clarke, PLA, ASLA - Principal


Bob's approach to site development is differentiating.  His extensive experience in both site development and landscape architecture is illustrated in his broad breadth of projects including master planning, urban design, stormwater mitigation, corporate and institutional landscapes, wetland replication and several award-winning projects highlighting both disciples.

As a landscape architect, his approach to a project always starts with the aspiration to preserve and rehabilitate the natural environment while demonstrating his commitment to create exceptional and enduring spaces.  As a civil engineer, his ability to see creative solutions to site constraints, work within limited budgets and time sensitive deadlines, and navigate the complex state and local permitting process minimizes the pressure that is part of the decision-making process for the client. Combined, both approaches allow for exploration of design solutions that can advance projects beyond the typical or expected.  

Bob holds a Bachelor of Science in Landscape Architecture from the University of Massachusetts, Amherst and is registered as a Professional Landscape Architect (PLA) in Massachusetts, New Hampshire and Rhode Island.  He is also a Member of the American Society of Landscape Architects (ASLA) and a Council of Landscape Architectural Registration Boards (CLARB) Certified Landscape Architect.

Timothy J. Williams, PE - Principal


Tim has over three decades of hands on engineering know-how.  This is reflected in his extensive portfolio of public, municipal and private sector projects. He is actively involved in the preliminary design through construction administration on projects ranging from commercial/mixed use to multi-family residential, hospitality, institutional, and infrastructure.  Industry recognized for his expertise and ability; he has managed the design efforts for some of the largest development projects in the Northeast.

Tim brings over 30 years of engineering experience to every project.  His focus over the years has included specification writing, quantity cost estimation, field studies, investigations and analysis, as well as construction oversight.  As a strong advocate for sustainable design and planning, he is committed to responsible, yet cost effective solutions to site challenges.

Tim holds a Bachelor of Science in Engineering from Central Connecticut State University and is registered as a Professional Engineer (PE) in Massachusetts, Maine, New Hampshire and Connecticut.  He is also a Member of the American Society of Civil Engineers (ASCE) and the Boston Society of Civil Engineers (BSCE).
