I attended my first group session last night and was so impressed with the topic that was covered and the comments that the class made. Very informative. The atmosphere was extremely welcoming to each member of the group. I’m looking forward to attending each class and achieving my goal of sobriety.

Dr. Daniel is extremely professional, knowledgeable, supportive, understanding, organized, and respectful. From the start he made everything calm and nonjudgmental. He explained everything he was doing and why he was doing it. He treated me like a person and not a statistic or lost cause. Even when I slipped in my program he was there to help me up and continue my progress. He did not give up on me or judge me. And I made it through and was able to recover from something I thought would be a slave to the rest of my life. Great doctor.

Dr. Smeester came prepared with a thorough plan to execute for success. Goal upon arrival to his office was to be off pain medication. Problem presented 35 y/o patient 4 months post knee replacement where the orthopedic surgery team wanted to slowly taper medication. After speaking to network, Dr. Smeester was told to be the best at helping achieve the goal of getting off pain narcotics safely and aggressively. The plan he presented and offered was and is great. Thank you Dr. Smeester.
