More about Dr. Hammen

Medication Crisis?

We know what happens when you suddenly cut someone off from pain medications.  The data exist: overdoses from street drugs increase and people die.  

When a doctor suddenly stops prescribing medication that is "addictive" or causing physical dependence, the result is devastating.

"The pain is about the same as  it was on the pain medications.  I am less active now, but it's only been 10 days - I am so glad I found you and that I'm not standing in line at a methadone clinic.

I honestly thought the other doctors would have something like what you are doing, but they just aren't even real medical clinics. It could have been so sad, so much worse." -OJ

 You have choices, options.

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 escape, your out, often times a very specific drug - all while harming your relationships and self-esteem, making it more difficult to succeed in work and school, to live freely.

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
