I worked with Dave for several years on an extremely complex, safety-critical system. It was clear from the start that he has a passion for the safety and experience of the patient, but also that he excels at deconstructing complexity to uncover the root needs of stakeholders and the requirements of the system. He brings a collaborative attitude every day and communicates with clarity, conviction and humility. I would highly recommend Dave for any team!

Dave was chartered with learning the Reliability Discipline through executing Reliability Enhancement Testing and the Failure and Corrective Actions that resulted from this testing. Through these efforts, Dave proved to be a very thorough and technically sound engineer. On numerous occasions, Dave willingly supported extended work hours to meet Program Commitments. Dave is a bright, talented, and ambitious engineer who I would recommend to any engineering organization."
