Beth HaMedrosh Hagodol – Beth Joseph, known locally as BMH – BJ or simply BMH, and for a period after 2012 also known as The Denver Synagogue,[1] is an Orthodox synagogue located in Denver, Colorado, in the United States.

[2] Beth HaMedrosh Hagodol (BMH-the Great House of Study) originated as a modern Orthodox synagogue in 1897 under the leadership of shoe merchant Henry Plonsky.

BMH laid the cornerstone of their new building on Rosh Hashanah 1916 and was a major civic event, drawing DU chancellor and former Colorado governor Henry Buchtel, Judge Benjamin Barr Lindsey and former Denver School Superintendent William H. Smiley.

[6] Stanley M. Wagner became the rabbi in 1972 and BMH joined the Orthodox Union, but it maintained several ritual practices not typically followed at OU-affiliates.

It was the only surviving example of a seating style that had previously been present in a substantial number of Orthodox Union affiliated synagogues, and resigned from the OU after learning the organization planned to expel them over the mixed seating issue.
