Interventional Pain Doctor

"My hospital hired Mr. Wichern after I had concerns about the increasing number of opioids patients I was taking on.  Mr. Wichern came in and reviewed my office’s procedures, policies, and records, and gave me the peace of mind I needed to continue to treat my chronic pain patients."
