"Energy and Water Development delivered the complete package — technical design, financial strategy, and long-term vision. Their tri-generation solution will power Illinois Tech efficiently for decades to come."
"Suresh's command over his professional knowledge and his ability to apply the same to drive results is one of his biggest strength. I have known Suresh to be very detail oriented and someone who is keen to go to depths of any issue to solve the same. He has sound technical skill sets combined with very good business sense. He would be great a asset to any firm that he is working for."
"I had the pleasure of working with Suresh during a period when his company was looking at purchasing my company's facility Colmac Energy Mecca. Out of the numerous companies and due-diligence personnel I encountered, that by far Suresh the most knowledgeable of the technology incorporated within the conversion process. His technical understanding was second to none, on top of which the questions he asked me during the due-diligence process were without doubt the most educated ones that I received from literally hundreds of people both technical and non-technical. It was and is a pleasure to be associated with such an individual as Suresh that has an equal passion for what he both does and believes in. One of the best energy related engineers I have come across in a very long time."
