Very professional service and extraordinary attention given to an individual patient. Dr Smeester has contacted me every hour the first day of my treatment to see how I feel and follow up daily with me to see how I progress. He designed a solid path toward a successful treatment. I am so thankful to Dr Smeester and his staff.

Dr Smeester has brought me piece of mind in dealing with my pain issues. He listens, and is mindful of everyday stress. I should have gone to him years ago. I look forward to him taking care of me while I try to fix my body. They really care about you. Front desk is great as well.

Outstanding on every level. Dr Smeester is patient and very easy to talk with about my health issues. He cares and I can count on him. Lucero is the other half of the equation for me. She never panics, even if I do, and she always follows through on her promises. I would definitely recommend Diablo Valley treatment center!

Saved my life. Best decision I ever made was coming to see him. He REALLY cares about his patients. He’s also non-judgemental and a brilliant top-tier doctor for addiction.

Dr Smeester is a lifesaver. He’s guiding me through a nasty, unexpected detox situation and I couldn’t be more thankful.

There is no doctor better than Dr. Dan Smeester. He is kind compassionate and throughly understands what Chronic Regional Pain Syndrome (CRPS) is and how ketamine infusions are the best way to treat CRPS. Right after he starts the ketamine drip, I quickly fall asleep because I finally find peace! After a 4 hour ketamine treatment and a 3 hour recovery, I feel great. His medical assistant, Lucero, is also so kind and wonderful. If I am in a lot of pain, she always try’s to find a way to get me in as soon as possible.
