Meet Our Team

Brian Holland - Certified Consulting Meteorologist Brian Holland

Mr. Holland is the lead member of the BREEZE data processing team and works with clients around the world to generate high-quality model-ready meteorological and terrain datasets that can withstand regulatory and scientific scrutiny. He is experienced in generating input data for numerous models including AERMOD, ISC3, and ADMS, and has expertise in utilizing a variety of techniques to obtain a scientifically defensible datasets including use of the similarity theory-based mixing height estimation, data from onsite meteorological stations, and the merging of data from multiple sites. He works with regulatory agency contacts to ensure that the most up-to-date approach is used in every dataset processed. 

Mr. Holland also serves in several technical roles from consulting on hazardous release modeling projects, to software testing and requirements development, to scientific EHS software development including real-time air dispersion modeling systems. As one of the primary environmental and safety modelers in the BREEZE group, he has experience in areas ranging from air dispersion to explosion modeling. He is experienced with the AERMOD, DEGADIS, INPUFF, and CALPUFF models, among others. His modeling work includes clients in the oil and gas, mining, petrochemical, and other chemical industries. He is the primary instructor for the BREEZE air dispersion and accidental release modeling training courses. He also serves as one of the technical support personnel for the full line of BREEZE software products.

In his early career he worked as a staff meteorologist/modeler for the US EPA, Office of Air quality Planning and Standards. Over the past 38 years in consulting, he has managed and contributed technically to a wide variety of environmental assessment studies including Prevention of Significant Deterioration (PSD), nonattainment area net emissions modeling, state and federal air toxics analyses and human health risk assessments, and State Implementation Plan (SIP) preparation. 

George has provided litigation support as an expert witness including technical reviews, affidavits, and testimony in cases involving air quality modeling and meteorological considerations, toxic torts, and exposure. He was an instructor as well as director of the EPA Air Pollution Training Institute (APTI) Air Quality Modeling Application Course No. 423 from 1990-2005 and now teaches the same course under state and regional agencies as well as annually for Trinity Consultants. George is also a Qualified Environmental Professional (QEP), a member of the Hamilton County, Ohio Air Quality Policy Advisory Committee, and former chair of the Meteorology and Modeling Committee of the A&WMA.

Tony SchroederTony Schroeder

Tony is a meteorologist and modeler with an M.S. degree in Atmospheric Science from Pennsylvania State University. He has over 15 years of experience in atmospheric dispersion modeling and air quality permitting. He has prepared and managed numerous ambient air quality assessments and performed extensive modeling using diverse meteorological data sets and the ISCST3, AERMOD, and CALPUFF software applications to assess potential exceedances of significant impact levels (SILs),National Ambient Air Quality Standards (NAAQS), and Prevention of Significant Deterioration (PSD) increments for both air permitting and State Implementation Plan (SIP) development purposes. 

Tony has also completed regulatory and non-regulatory air toxics analyses and human health assessments using such diverse models as INPUFF, DEGADIS, ALHOA, PHAST, AERSCREEN, VISCREEN, and AERMOD. He has experience providing litigation support for cases involving air dispersion modeling as an expert witness in the form of written reports and verbal depositions.  He is also an instructor for Trinity’s national training courses Fundamentals of Air Dispersion Modeling and Dispersion Modeling for Managers.  Tony is a member of the American Meteorological Society and the Air & Waste Management Association.
