For the eighth year in a row, Henderson Engineers earned a ranking in the annual Top 10 Electrical Design Firms list by EC&M, a notable electrical systems trade publication. EC&M’s rankings are determined by electrical design revenue earned during the previous year. Accordingly, Henderson’s 2021 standing is based on the $47.6 million in electrical design revenue earned by the firm in 2020.

“We are excited to be ranked in EC&M’s Top 10 list yet again,” said Rich Smith, Henderson’s president and CEO. “This ranking exemplifies the hard work and commitment of our team. Regardless of the challenges that 2020 brought, their dedication ensured another successful year. We couldn’t be prouder and more thankful for the work we accomplished, and we are just getting started.”
