In 2020 he was the lead medical advisor for the City of New Haven COVID isolation respite shelter, helping to develop the strategic and operational respite document, and was awarded a Proclamation by New Haven mayor Justin Elicker for his commitment to the public health and well being of our community, and awarded a C.H.A.I.
