I have nothing but incredible things to say about my experience with Dr. Mosser and his team. Being transgender, it sometimes feels that you are constantly fighting battles when it comes to your medical care. Dr. Mosser was such a breath of fresh air. He is a professional that genuinely understands the transgender community and values the opportunity to contribute towards changing transgender lives.

Surgery with Dr. Mosser changed my life. I continue to be impressed by my results. He listened carefully to what my goals were with surgery and executed them perfectly. This is a physician who is not only a surgeon, but an artist.

Thank you Dr. Mosser and your team for making me feel confident in my body and inspiring me to live everyday as my authentic self.

Surgery with Dr. Mosser has truly been a transformative, life-changing experience. Today I am comfortable and confident to say I am trans: a conclusion that took years to reach.

Navigating through the US healthcare system has been an ongoing challenge, especially as a foreign-born, non-binary person. Growing up between two cultures and juggling with differently defined gender roles, I have struggled with the idea that I wasn’t “trans enough” to deserve or qualify for treatment (which is, of course, not true at all!) The moment I walked into Dr. Mosser’s office, I knew I was welcomed, listened to, and taken seriously. Thank you so much for holding a safe, respectful, and liberating space for all folks on the spectrum.

I am fortunate and privileged to have made it this far with the help of such a great support system. Without the weight of dysphoria, my mind and body feel so much lighter; even breathing seems a lot easier now. I am finally at peace with the person in the mirror staring back at me, and I remind them how proud I am for who we are, the choices we’ve made and for surviving the little everyday struggles.

As a non-binary person, I wavered for a long time about whether or not to have top surgery. Working with Dr. Mosser’s practice helped me decide to go for it, and in retrospect it’s one of the best decisions I’ve ever made.

Like many transgender people, I struggled with feeling comfortable in my body before surgery, and that made it hard for me to take good care of health, like exercising and going to the doctor. I’ve been a runner for a long time, but going for a run always made me self-conscious. The first time I went for a run after recovering from surgery it felt so light and easy that I literally laughed out loud running down the sidewalk. Now when I exercise I can enjoy the way it makes me feel, instead of trying to avoid thinking about my body. As great as having top surgery was for my mental health and my gender identity, it’s also been really important in helping me take better care of my physical health.

Dr. Mosser’s practice stood out to me because everyone was very competent around working with non-binary clients, and Dr. Mosser was really willing to listen to my particular goals for surgery and make them happen. Moving through the world after surgery feels cleaner, like I used to devote lots of mental energy into dealing with my dysphoria and I just don’t have to anymore. Just about every day I notice some little thing that feels easier than it used to – taking a shower, getting dressed, going to the gym, even hugging a friend. And every day, I feel grateful for this new comfort in my body.
