More about Dr. Hammen

Getting back on track

Substance use can get people off track in all kinds of ways- drinking more than you mean to, overusing your prescribed medications, time spent making certain you have your drug - harming your relationships, making it more difficult to succeed in work and school. 

Understanding both what tools you need as well as how to use them allows you to get back on track and live your best life.

"Dr Hammen saved my life. I had just given up hope, and he appeared like a guardian angel - he came to me. It hasn't been easy, but no one else understood or listened. I was on the verge of losing everything. . .of just giving up. 

Everything he said about what to expect at each step, the way he explained the medications - I've never had a doctor like him before. For the first time I understood why this was so hard and knew it would get better." -PF
