Cohen Health and Performance who we are

movement coaching - knee bend

Physical therapy and performance training for those that take their health seriously

We believe that all active people deserve the high quality and individually focused care that is typically only reserved for elite athletes. Our mission is to enhance the lives of individuals who desire to live an active lifestyle by providing elite level physical therapy and performance training. This means that we treat you as an individual, rather than splitting time between 2-3 patients at one time. This helps you to overcome injury and return to performing at your highest level in the least amount of time!


Dr. Zac began his career working in professional sports. He noticed a large discrepancy between the quality of care that elite athletes receive when compared to the normal active public. This inspired him to create Cohen Health and Performance, a place that treats everyone as if they are a professional athlete!

He graduated summa cum laude from Northeastern University in 2011 with his Doctorate in Physical Therapy, and also became a Certified Strength and Conditioning Specialist (CSCS). While at Northeastern he worked as a Physical Therapy Graduate Assistant for the New England Patriots, and served as a strength and conditioning coach for Northeastern University athletics.

Prior to moving to Maryland, Zac was a Performance Physical Therapist with EXOS (formerly known as Athletes’ Performance) in Dallas, TX where he treated and trained the world’s most gifted athletes from throughout the NFL, MLB, NBA, MLS, and various Olympic teams.

Dr. Morgan Vasiliu grew up playing a variety of sports and knew from the time she was in high school that she wanted to work with athletes and athletic populations. During college, Morgan went on to pursue an Athletic Training Certification from Messiah University where she also played field hockey. Wanting to learn more about how to blend the sports & rehab world together, she went on to pursue her Doctorate in Physical Therapy from The George Washington University.

During her clinical rotations at a variety of sports-specific physical therapy settings, she fell in love with the ability to blend rehab & performance training, but often felt limited by the lack of quality time with patients. She was intrigued by CHP because of the ability to spend one-on-one time with patients, allowing her to achieve the best results possible for them. She now helps patients get back to doing what they love while walking them through the process of achieving lasting results.

Dr. Sebastian was a Division 1 baseball pitcher until a shoulder injury cut his career short. This led him to discover his passion for helping others recover from injury, and perform the sports and activities they love. His journey began as a baseball coach, private instructor, and performance coach before he decided to pursue a career in physical therapy so that he can best serve athletes of all ages.

Sebastian played baseball at St. Bonaventure University, where he was a conference starter as a freshman. Following his injury and retirement from baseball, Sebastian began coaching and working as a full-time baseball instructor in Ohio. From there, Sebastian had coaching stints in Florida and New York, both as a head coach and pitching coach for middle school and high school athletes. Sebastian completed his Bachelor of Science in Exercise Science from SUNY Fredonia before attending the University of Rhode Island, where he graduated as a Doctor of Physical Therapy. He completed clinical affiliations at Precision Physical Therapy and Performance in Pittsburgh, PA, and at Force Physical Therapy in Miami, FL.  During this time, he focused on baseball training and rehabilitation, and worked with professional baseball and football players, and college athletes preparing for the NFL Combine.

Sebastian is a Certified Strength & Conditioning Specialist through the National Strength & Conditioning Association. He uses his blend of knowledge in physical therapy, strength & conditioning, and coaching, to best serve an active population.


Not far from home, Dr. Kelly was born and raised in the DMV area. She spent the majority of her time growing up swimming and playing soccer, and carried on her passion for sport by committing to swim Division I for Virginia Tech.

During her 4 years as a Hokie, she earned a bachelor’s degree in Human Nutrition, Food, and Exercise, as well as becoming a team captain and school record holder. Her time spent in the athletic training room, both as an athlete and an intern, is what pushed her to pursue a career in physical therapy.

Kelly continued her education at Emory & Henry College where she graduated with a Doctorate of Physical Therapy. She gained experience through her clinical rotations working with a variety of patient populations including paralympic athletes, pediatrics, high school athletes and weekend warriors. Kelly is a Certified Strength and Conditioning Specialist, as well as USA Swimming Certified Swim Coach.

Outside of the clinic, you can find her coaching for the Potomac Marlins or training for a running race/triathlon!


Personalized care

We treat you individually so that you get back to performing the activities you love as quickly as possible. Our physical therapists will never compromise the quality of care that they can deliver by treating multiple patients at the same time. While this is common practice at other physical therapy clinics, this is simply not the CHP way!

State of the art facilitiesCHP is located in downtown Bethesda consisting of a physical therapy
clinic and 3,000 square foot performance training facility.
