Stephen P. Lordon, MD
Medical Director • Pain Management Specialist
“I founded Summit Pain Management in 2004 with the goal of establishing the best multidisciplinary and interventional pain clinic in the Intermountain West. My training, academic experience and board certifications in Anesthesiology and Pain Medicine have provided me the extensive medical background needed to accurately diagnose and treat patients.
“As a pain medicine specialist, I have learned the importance of being an active listener in order to provide compassionate care. At Summit Pain Management, patients receive a thorough evaluation and explanation of their pain. Working together, we devise a comprehensive treatment plan to meet individual goals.
“I find it very gratifying to help patients with acute or chronic pain concerns. Often, patients come to us because they believe they have exhausted their treatment options. My greatest satisfaction comes from assisting patients to improve their pain experience and returning them to their productive and active lives.”
