I am a physician (M.D.) who is Board Certified in Anesthesiology, Pain Medicine, and Addiction Medicine.

In addition, my training and education include safe opioid prescribing procedures, interpretation of prescribing records, assessment of patient responses to prescribed opioids, and overdose prevention education and practices.
