Cohen Health and Performance who we are

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. Debra Rios is Vice President of Cohen Health and Performance. She received her Doctorate of Public Health in Health Promotion and Behavioral Sciences from The University of Texas School of Public Health. She has also been a Certified Health Education Specialist (CHES) for over 13 years. Dr. Rios has worked in a variety of public health settings and focus areas including worksite wellness, teenage pregnancy prevention, tobacco research/prevention, and obesity prevention.

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!

Growing up in Northern Virginia, Jordan was constantly outside hiking, kayaking, or training for half marathons.  This led her to study Human Nutrition, Foods, and Exercise at Virginia Tech. During her time at VT, Jordan held multiple leadership positions as the president of the school’s Make-a-Wish chapter, a trip leader for the Outdoor Club, and as one of the school’s tour guides for transitional students. No matter the position, Jordan just wanted to help others succeed.

After leaving Blacksburg Virginia, Jordan continued her doctoral education at Shenandoah University where she completed an internship with Explosive Performance. This internship provided her with opportunities to train professional athletes and collegiate teams.

Today, Jordan finds herself spending most of her free time powerlifting, paddle boarding, or cheering on (or most likely yelling at) her favorite team, the Philadelphia Eagles, every Sunday. She finds the most joy providing education to her patients on movement and exercise to help them get back to a pain-free lifestyle!


Dr. Ethan has always had a passion for athletics and knew he wanted to follow a career path that would allow him to help injured athletes return and stay on the field. This passion for athletics led him to receiving his bachelor’s degree in athletic training from the University of Delaware where he worked exclusively with Division 1 athletes and completed two separate NFL internships.

Ethan continued his doctoral education at Florida International University in Miami. During his time at FIU, Ethan obtained his Certified Strength and Conditioning Specialist certification and completed an internship at EXOS Arizona– a top sports performance clinic in the U.S. Ethan strives to bring his expertise and diverse athletic experience to CHP to provide his clients with the individualized care that will keep them thriving on and off the playing field.

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.
