Dr. Daniel Negron earned his Bachelorโs degree in Psychology with a concentration in Pre-Physical Therapy from Trinity College, where he also played football for the Bantams. He went on to receive his Doctorate in Physical Therapy from Tufts University School of Medicine.
Dan built his clinical foundation at Ripple Physical Therapy, where he quickly advanced from staff therapist to Lead Physical Therapist while mentoring developing clinicians within the organization. He played a key role in expanding the practice to two locations and later served as Clinic Director of the Brookline location, helping shape both patient care and clinic growth.
He later practiced in Brookline Village within Core Collective, a multifaceted strength and wellness facility, and has been an active part of the Backyard community since its inception. Dan combines hands-on techniquesโincluding sports massage and dry needlingโwith corrective exercise and strength and conditioning principles to help patients build capacity, regulate the nervous system, and return to the activities theyโre most passionate about.
Outside of the clinic, Dan is always on the hunt for Bostonโs newest restaurants. You can also find him in the gym lifting heavy and diving into HYROX-style training.
