Dr. Carly Holthausen
PT, DPT
My name is Carly Holthausen! I was born in a small town in New Jersey, but my family moved to South Carolina when I was young, so I grew up in Lexington and claim it as my hometown. I tried my hand at many sports growing up, but ultimately landed on soccer and running (the only ones I was pretty good at). My passion for PT came from growing up with my dad who suffered a spinal cord injury as a young adult. Over the years, he has been in and out of PT for lots of things related to his original injury. I graduated from Clemson University (don’t hate, Go Tigers) in 2016 with a BS in Health Science. I then moved to Charleston for PT school. I graduated from the Medical University of South Carolina in 2020 as a Doctor of Physical Therapy. I continued to play soccer while in school (shout out to Dr. Thavi who I met playing club at Clemson!), and fell in love with urban hiking in CHS and hiking in the mountains in the upstate.
I have a few years’ experience in the field now, and have realized helping people heal, no matter the setting, the injury, the background, fills my cup. So many people helped my dad through the toughest of times – I wanted to be that for others, and this field has given me that opportunity. I’m excited for this new chapter in my life and my career and I am excited to be part of the Vertex team!
In my free time, you can still find me trying to relive the glory days playing soccer in adult rec leagues, hiking in SC’s state parks, in the gym, or in a local coffee shop feeding my *boujee* coffee addiction!
