Kariann, I found my speech therapist worse than useless (and she SPECIALIZED in working with trans people). I learned from youtube videos (CANDIFLA), and I'm very happy with my voice.
I'm tone deaf, so your person's advice wouldn't have helped me one bit. For me it was more finding the right position in my throat, after which every thing that came out of my mouth, regardless of pitch, sounded female.
Resonance is much more important than pitch, in my experience.
