Just had my first appt with Hattie and found her to be excellent. I had a lot to tell her and she let me get it all out and then asked her questions. I could tell she really wanted to help me, she gave me good feedback and recommended new medicines as she could tell that what I was on wasn't helping me. I am looking forward to my next appt and to feeling better soon. Thanks Hattie!

I love that she makes me feel comfortable. Mental health can be difficult to accept so having someone that listens and not judge is helpful. She is also knowledgeable and provides different options.

I love how she takes the time to listen to my issues. It helps to be heard and acknowledged by a professional, and be guided holistically. She is very warm and solution-oriented at the same time, which I really appreciate.
