Trinity Cathedral is a historical landmark constructed in 1927 at the intersection of 1st Avenue and Roosevelt in Phoenix. John Chonka worked closely with the Episcopal Diocese of Arizona, and the City of Phoenix Historic Preservation Office as well as recommending and working in collaboration with the general contractor to ensure that the restoration of the Cathedral’s interior be carried out in an appropriate, and cost effective manner. The Cathedral’s elaborate glass work, emphasis on traditional materials and attention to detail were key components in both the original design and restoration. Trinity Cathedral Website
