Hi Elaine!
i am currently enrolled in a three year intensive certificate training program known as "somatic experiencing." When I finish it, I will be more equipped than I am now to provide high quality training on the impact AND remedying of trauma. You may want to check it out. Also, the JRI institute in Brookline, MA also offers a nine month certificate in trauma studies (Bessel Van Der Kolk's Institute). That's a worthy and highly regarded institute of training. Lots of people "claim" to have trauma expertise, but trauma studies is a broad area, with research emerging daily, and I believe people need a robust history of working with a traumatized population in addition to formal trauma training to really come close to that claim.
