I am a compassionate individual that utilizes professional experience, personal experience, and passion to help others suffering from addiction. I started at Discovery assisting the Detox Counselor with running groups and ensuring they had everything they needed while in our care. I have success with preventing clients from leaving against medical advice by connecting with them and empowering them to keep going. I now assist clients and their families by securing sober living homes and aftercare. I believe it is vital to be consistent with your treatment plan in order to achieve long term recovery.
