  • "We recommend working with CR2 Engineering on building systems projects"

    Miriam School Alarm

    The Miriam School is a specialized non-profit school in St. Louis, Missouri that relies on technology-based systems to ensure success for our students and educational program. We recently engaged CR2 Engineering to provide consultation and design for the network infrastructure, classroom technology systems, and enhancements to our security systems, including video surveillance, and could not be happier with the professional approach and expertise CR2 provided in support of our needs. …our consultant, was responsive and easy to work with throughout all aspects of the construction phase and his expertise has been invaluable.

    CR2 provided a clear explanation of the options available and associated costs involved and I would recommend them to any school that is considering upgrades to their security systems, classroom technology, or network infrastructure systems.

  • Rob H. Director of IT Service for Ladue School District
    To Whom It May Concern: The Ladue School District, located in Ladue, Missouri, an inner-ring suburb of St. Louis, contracted CR2 Engineering to provide a security assessment and design for our Ladue Horton Watkins High School $82 million renovation project. Pleased with the results of the security assessment and design, the concept is planned to be replicated throughout the entire district. The Ladue School District services approximately 4,250 students, 1300 of whom attend the high school. District facilities, including the swimming pool, track, fitness facility, district conference rooms, and performing arts center, are also available for use by members of the community. Security is a priority for not only our students and faculty, but the people who live in the Ladue Schools community. The Ladue School District recommends working with CR2 Engineering regarding security assessments and design as they have been a professional addition to our project team. Sincerely, Rob Highfill Director of IT Service
