Mystery juniper

[esteve59]

I am not sure what kind of Juniper this is except I believe it is a "golden" somthing.....in the spring time it has a nice golden hue.
you can see by the pics the foliage is not as tight as a shimpaku.
So,does anyone have any idea what it might be and any reason I should not attempt to start trimming it back ??

Thanks,

Could be parsonii or sabina judging from the long scaled grow. I'd wait till growing is done to trim.
