I hope you find an MT you are looking for! If it helps - I've found that people with a lot of trap tension also have tight pectoralis muscles. If the pec muscles are released, it helps get the shoulders back into alignment so relieving the tension in the traps is a lot more sustainable!

If the pectoralis are tight, they pull the shoulders forward, stretching out the traps so they're perpetually tense, so a massage might feel nice, but won't help the problem in the long run ;-)
