No, North Mammon is a fictional city that was created for Criminal Minds. According to the Criminal Minds Fan Wiki, it is implied that the town is located in Allegheny County. Allegheny County is a real county in Pennsylvania. You may know it for being the county where Pittsburgh is located. I have never seen it on the internet anywhere but I think that North Mammon represents Clairton PA. The football team's colors are black and orange. The Clairton Bears football team wear black and orange uniforms. North Mammon made the state championship in the episode. The Clairton Bears have won three consecutive state championships. Clairton is located in Allegheny County where football is what the town is all about like North Mammon. In the background of the North Mammon Police Office are smokestacks, suggesting that it could be a mill or steel town which Clairton is as well as other towns along the river.
Philadelphia Pa
North East, PA which is northeast of Erie, PA and southwest of Westfield, NY.
Fredericktown PA
Yes, it was. It was filmed in Doylestown, PA. A suburban town north of Philadelphia about 26 miles from center city Philly.

Looks like Philadelphia. They are pretty close, but Salt Lake City is about a degree further north than Philadelphia.
The closest small towns are Ardmore and Wayne, but the closest real city is Philadelphia and it is only about 15 minutes away.
Madrid is at almost exactly the same latitude as Pittsburgh, PA.
The driving distance from Warren, PA to Grove City, PA is 86 miles.

You generally don't find cities at even degree intersections of latitude and longitude, but I guess you lucked out. 40N 80W is only 53 feet from the intersection of Mulberry St and Potters Alley in Frederickburg, PA. More of a town than a city, actually; the nearest city would be Pittsburg, PA, about 20 miles north.
