What is TMS
R.H.
Amazing experience with this specialist, he was immensely knowledgeable, excellent bedside manner, and very clear when communicating and diagnosing. Fantastic first psychiatrist experience.

I have been through so many different doctors who were completely arrogant, and didnt want to listen to me. Wallace is absolutely amazing and refreshing as a provider. I could tell that he listens to me and cares about helping me find the right medication. I couldn't recommend him enough, I feel really well taken care of. He makes himself available for questions and is very kind and compassionate.
L.K.
Highly recommend, took time to go over history and was very patient and understanding. Showed a genuine caring side and is an excellent listener. Incredibly perceptive. Definitely a provider worth working long term with.
L.D.
I genuinely liked him alot, it’s been hard to talk about anything regarding mental health because I never feel listened to or comfortable. But in this appt I felt like i was heard and felt validated. I felt okay to open up more and comfortable to share some personal things. I highly recommend him and will be recommending him to my friends and family.
