finding reliable medical practitioners

[Frankie]

Hi - I am looking for a therapist in the NYC metro area ( Jersey side ) for my child who just turned 14.  Five months ago my daughter declared she was trans.  She is now he and has a new name and is single minded in his/her desire for testosterone.  She also has ADHD, depression, anxiety and a handful of sensory issues.   I am looking for a clinician who is willing to neither affirm or deny the trans identity.  Also, we told our child we would seek guidance from a gender clinic.  Does anyone know which one has the longest waiting list?  Our goal is for our child to be who they need to be but get the benefit of a natural puberty and wait to make any medical interventions.  Thanks.
