About Me

I am an anesthesiologist who is board certified in both anesthesiology and pain management. I have a strong interest and focus on treating pain that may arise from cancer and its treatments.

Plus and Minus IconIcon showing a plus/minus toggle, indicating that the surrounding element can be opened and closed.

I was drawn to this field over the course of my medical training as I witnessed the difficulty faced by many patients as they struggled with pain. I learned that there are tools we can offer patients to control their pain, and I knew I wanted to be involved in this work.

The interventions I use provide individualized and effective pain management. These include ultrasound, fluoroscopy, and CT-guided imaging. I also utilize approaches such as radiofrequency, cryoablation, chemical ablation, and stimulation techniques. I am a strong believer in employing the latest evidence-based research in my practice because many of these newer technologies offer great promise for our patients.

In addition to my work treating cancer pain, I spend half of my clinical time in the operating rooms as an anesthesiologist. I also instruct and mentor junior doctors who are undergoing specialty training in the areas of anesthesia and pain management.
