Dr. Mark Christensen, MD
Medical Director & Owner | The Refinery | Guntersville, Alabama

Double board-certified physician. Emergency Medicine specialist. Aesthetic and performance medicine practitioner. And the reason The Refinery exists.

From the Emergency Department to The Refinery

Dr. Christensen spent years working in high-acuity emergency medicine — long shifts, no sleep, and the kind of pressure that demands precision when imprecision has permanent consequences.

That background shapes everything at The Refinery. When you receive Botox from Dr. Christensen, you're being treated by a physician who has repaired complex facial lacerations under the highest stakes, who understands vascular anatomy not from a textbook but from years of hands-on emergency care, and who has managed medication reactions, complications, and adverse events in real time.

Most med spas cannot say that about the person holding the needle.

His Philosophy

'I see what chronic stress, hormonal decline, and neglected self-care does to people. I lived it. The Refinery exists because I believe physician-level expertise should be available in a setting that feels like it was built for you — not a hospital hallway, not a strip mall spa.

You should look refreshed, not frozen. Feel energized, not medicated. Perform at your best — not just survive your day.'
