At CGA, Stephen’s tasks are focused on acoustical design, noise control, vibration control, and environmental acoustics for high-technology facilities such as semiconductor fabs, university research laboratories, and healthcare facilities.

Nat Wongprasert, Ph. D.

Nat Wongprasert has been with Colin Gordon and Associates as a consultant primarily working in the field of structural dynamics and vibration control. He has extensive skills in implementing sophisticated finite element methods and applying advanced dynamics techniques to predict vibrations of structures. His consulting experience also includes: structural design and evaluation; vibration measurements and monitoring; identification of dynamical properties; predictions of ground- and structure-borne vibration from various sources (train, vehicle, forklift, power generators, etc.); evaluation of isolation systems; and tool pedestal design and testing. As part of the company’s on-going R&D, he is actively involved in developing and validating mathematical models and computer simulations used for vibration and dynamic response predictions.

Blong Xiong

Blong has been with Colin Gordon Associates since 2006. As a Senior Consultant at Colin Gordon Associates, his activities include project management, field measurements, and design support. He has been involved in the design and validation of multiple high tech manufacturing facilities, academic research laboratories, and healthcare facilities. Blong has extensive experience with instrumentation and field data collection for both vibration and acoustics related projects. His work also includes structural vibration analysis using Finite Element Analysis, environmental noise modeling, and long term vibration and noise monitoring. Prior to Colin Gordon Associates, his work experience was in development and testing of noise control applications for automobile interior cabins. 

Steven Lank, LEED AP

Steven Lank joined CGA in the spring of 2010. His undergraduate thesis at the University of Virginia dealt with frequency analysis of guitar woods for the purpose of characterizing sound. His consulting activities at CGA have focused upon vibration and noise measurements for high-technology facilities, structural analysis and evaluation, finite element modeling, construction vibration monitoring, HVAC noise analysis, and environmental noise modeling. Prior to joining Colin Gordon Associates, Steven worked 8 years as a structural designer of support structures for roof and floor systems in residential and commercial construction projects. He also oversees CGA's efforts in sustainable design, including LEED certification.

Jonathan Lui, P.E.

Jonathan Lui joined CGA in the spring of 2011 after working two years as a structural engineer with KPFF Consulting Engineers. While there, he had the opportunity to work on several commercial projects varying from complex steel frame hospitals to simple tenant improvement jobs. His consulting activities at CGA have focused upon vibration control, finite element modeling, and vibration measurements for high-technology facilities including semiconductor fabs and research laboratories as well as commercial structures such as parking garages.

Lee Gorny, Ph. D.

Lee came to CGA in 2019 with seventeen years of experience in noise control engineering, acoustics and mechanical design. Here, he has focused on projects related to acoustical design and modeling, structural simulation using finite element analysis (FEA), and in measuring noise and vibration at industrial, commercial and high technology facilities. Prior to this, Lee worked at the National Institute of Standards and Technologies (NIST) developing a long-wavelength acoustical flowmeter (LWAF) and as an R&D engineer for SunPower Corporation, specializing in product design, simulation, integration and optimization.

Alec has been with CGA since July 2018. His activities have focused on signal processing, vibration and noise measurements, finite element modeling, HVAC noise analysis, environmental noise modeling, analysis of construction-induced vibration, and various internal research and development projects.

Leona Ching

Leona has over 25 years of experience in various industries and has been with CGA since 2005. Her concentration is in several areas such as accounting and finance, project coordination, office management, and human resources.

Decades of Experience

Colin Gordon Associates was formed in March 1990, and provides specialized consulting services in acoustics and vibration control. The firm has grown steadily from a one-person firm to a strong organization offering services world-wide. CGA has evolved to provide a variety of services ranging from sophisticated vibration and noise control to solutions of more mundane problems that may arise.

CGA is the world leader in the design of low-vibration and low-noise environments for technological buildings, but we work extensively in many other sectors as well. On many projects, the company serves as a member of the architect/engineer design team. On others, the company acts individually and directly with the owner. On yet others, CGA provides oversight support as a peer reviewer, owner’s representative, or via monitoring services. 

Colin G. Gordon

Colin Gordon (1934-2005) founded the firm that bears his name in 1990 and worked in the field of acoustics research and noise and vibration for over thirty-five years. Twenty years were spent with the firm of Bolt Beranek and Newman (BBN), the firm largely responsible for developing the engineering science of acoustics between 1950 and 1970. Five years were spent with the Institute of Sound and Vibration Research (ISVR) at the University of Southampton. In his last twenty years, the microelectronics industry was a key area of focus, with the design of low-vibration facilities for the research and fabrication of integrated circuit "chips". Colin developed a strong and unique reputation in this specialized field. Colin was widely recognized within the microelectronics industry for his contributions to the understanding of the vibration and noise environments of technology buildings. He pioneered many of the now-common analytical approaches to floor design and the analysis of noise and vibration from ducting and piping. He was co-developer (with Eric Ungar) of the widely-used vibration criteria for vibration-sensitive facilities. He had mentored many of the current generation of vibration consultants in this field.
