    As a trans masculine person in need of reproductive health services, I was very nervous heading into this appointment because I wasn't sure what to expect in terms of trans competency and how welcome I would feel. From the reception desk to Dr. Diaz, everyone I encountered demonstrated trans competency. I felt welcomed, affirmed and respected the whole time which eased my nerves and allowed me to engage more openly with my provider. As we move forward with next steps, I do have some questions about the level of specialty when it comes to trans health and unique considerations that may impact clinical options or decisions. I hope MGH continues to invest in training and PD in this area. That said, I have had a great experience with this provider and would recommend her to others.
