For those interested in looking a bit deeper into the Justice Through Music Project, the 990s for 2008-2010 can be found at Guidestar. I noticed that JTMP is not part of the Guidestar Exchange program, which program is intended for those non-profits committed to greater transparency.
The 2010 990 is interesting in Part VI where it shows that the governing body has no members. One assumes this means there is no governing body.
On Schedule O of the 2010 990, it is asserted that the 990 had been reviewed by the governing body before being filed. That would be the body that has no members.
The 2010 990 also lists the address of JTMP variously as 84169 Westmont Terrace, Bethesda, MD (which appears not to exist, so I’m guessing is a typo); 8416 Westmont Terrace, Bethesda, MD (which, from Google maps satellite view appears to be a residential address); and 8100 Beech Tree Road, Bethesda, MD (which also appears residential).
The (an?) Executive Director, unpaid per the 990, is Jeffrey R. Cohen. The accounting is done by Myra Lowenthal of Flax, Book & Co., CPA’s (sic), based in Highland, MD.
