Q&A with Dr. Lieber

IOF: What do you treat most frequently with regenerative medicine?

My most frequent area of treatment is spine. I feel very proficient in all areas of the spine having an Interventional spine background and having taken all of the SIS courses before the IOF existed. I hold board certification in Pain Medicine, as well.

IOF: Who are your biggest mentors in regenerative orthopedics and why? 

My mentors in the field are quite varied. I think that Dr. Centeno is my most important mentor. Through his training in the IOF, Regenexx and the AAOM, he has had the most profound influence on my career. I truly feel that without his guidance, I would still be in the dark ages of Regenerative medicine. 

Other mentors are Drs. Brian Shiple and Mayo Friedlis who are members and current and Past President of the AAOM. I have spent hundreds of hours with both of them and their training, but more importantly, their personal guidance and friendship have been invaluable.

IOF: How has IOF impacted you?

I think that the educational component is top notch. Everything from the conferences, lectures, cadaver workshops and ability to learn from the instructors one-on-one is fantastic! 

The educational videos are so important to me to be able to return to time and time again when planning and staging my procedures. Ultimately, the IOF has enabled me to continue to grow and develop as an Interventional Orthopedist. Learning new things and not stagnating in this ever changing field is what keeps it interesting, fulfilling and enjoyable for me. I continue to strive to improve to better help my patients and avert any plans to retire.
