Q&A with Dr. Derrington


IOF: Who are your biggest mentors in regenerative medicine & why?

Dr. Derrington: I have been fortunate to work closely with many outstanding physicians in the field of regenerative medicine, but two stand out for me.

Gerry Malanga, MD was one of the first physiatrists I met as part of a medical school elective rotation. After my month rotating with him, there was no question what speciality I wanted to pursue. Through his evidence-based and forward thinking approach to rehabilitation medicine, I was able to see the positive impact that I could have on patients’ lives. Working with Dr. Malanga as a part of the IOF has been a wonderful way to reconnect over 12 years after our first meeting.

Fellowship with Marko Bodor, MD was one of the best learning experiences I’ve had in my career. Marko is always thinking outside of the box and using his expansive medical and scientific knowledge to solve new problems when they present. The diagnostic and procedural skills that were developed during my fellowship have been invaluable, but advancing my problem solving skills for the patient that’s in front of me today may be the thing I’m most proud of.  Working with Marko was my first prolonged exposure to regenerative medicine treatments and it was so rewarding to see the outcomes our patients had. My fellowship experience gave me the confidence to fully commit to using orthobiologics in my practice.


What is your best advice for others wanting to get into regenerative medicine?

Dr. Derrington: It’s important to understand that using regenerative medicine isn’t as simple as putting something different in your syringe. It’s a complete mindset change in how you approach the patient from the initial encounter, making a diagnosis, and guiding them through treatment and rehabilitation. If you’re just getting into regenerative medicine, utilize the resources that are available to you. Go to conferences, take hands-on courses, and ask lots of questions. 

What do you most look forward to when attending IOF’s annual conference?

Dr. Derrington: The annual IOF conference is the only conference I’ve been to where I’m excited to hear every lecture. I love being able to reconnect with friends from all over the world and I learn so much from the conversations that are had after the lectures are over.
