"I have known the owner of Aptus Controls for 20 years. As a former colleague, I have had the privilege to work with Brian from the conceptual drawing stage through commissioning of systems he has designed and programmed. His attention to detail and knowledge in his field, especially with regard to SCADA, make him an outstanding teaming partner, one that we can always rely on to get the project right - the first time."
