About MJ2 Consulting, PLLC
John Gajda, Matthew D’Ambrosia, and Jonathan Poole formed MJ2 Consulting, PLLC in October 2017 to focus on solving complex problems for clients in the concrete industry. Mr. Gajda, Dr. D’Ambrosia, and Dr. Poole have extensive expertise in mass concrete planning and analysis, construction troubleshooting, durability and service-life assessment, specialized concrete mixture development, and product development research.
In 2020 we began expanding as Mr. Jon Feld and Ms. Victoria Jennings joined MJ2 to help our growing engineering practice. Jon joined us as an Associate Principal. He is a mass concrete expert and works on many projects that require thermal control plans or consulting related to mass concrete planning and construction. Vicki joined in late 2020 as a Senior Petrographer and brings her forensic and engineering expertise as we build a petrographic services group. Our vision includes adding other experts and we hope to grow in order to meet client needs and expectations. In early 2022, Dr. Jose Pacheco joined us as an Associate Principal. Jose is focused on concrete service life predictions, corrosion protection, and durability of new and existing concrete structures.
Dr. Toy Poole is also a part of MJ2, contributing his many years of expertise in cement and concrete laboratory testing and research to our team. Prior to joining MJ2, Dr. Poole served as a chemist at the U.S. Army Corps of Engineers Research and Development Center (Vicksburg, MS). He also served as a Senior Materials Scientist in Austin, TX and as an electronics technician in the U.S. Army.
