Meet Our Therapists


Physical Therapists

Mary Hood is a licensed Physical Therapist in the states of MD, DC, and VA. Her original degree in Physical Therapy is from the NYC program of Ithaca College, Ithaca, NY. She has furthered her training with the John Barnes Foundation of Paoli, PA and the Upledger Institute of Palm Spring Gardens, Florida, in Myofascial release, Craniosacral therapy, SomatoEmotional Release, Visceral Mobilization, and Lymphatic Drainage. She is currently furthering her knowledge of joint mobilization as taught by the Maitland Australian Institute.
Mary currently employs a combined treatment approach of traditional and alternative, manual and evaluation skills to address the whole body. Her emphasis in Craniosacral therapy and Myofascial release primarily accomplishes these results. This approach is often gentle and mobility enhancing, restorative to muscles, movements, postural alignment, and pain relieving.
Mary also includes a biomechanical or orthopedic approach, and specific internal organ or lymphatic vessel treatment whenever indicated. 

Christina Keltner PT, DPT, is currently licensed in DC and worked as a physical therapist in Acute Care prior to joining PMTA.   She enjoyed the hospital setting and continues to use knowledge gained there on a day to day basis.  

After growing up in Florida, she moved to NC to attend Elon University. She proceeded to move further north to Philadelphia in order to get her Doctor of Physical Therapy from Arcadia University. 

As a student, Christina spent her clinical affiliations at Cooper University Hospital in Camden, NJ, and Magee’s outpatient clinic in both the Day Rehab setting and also their Locomotor clinic. She rounded out her experience with Magee at their inpatient Acute Rehab setting in downtown Philly. She has a special interest in
patients with neurological diagnosis, and enjoyed her time as a student working with the Dan Arron Clinic, an exercise class held weekly at Arcadia for persons
with Parkinson’s disease and multiple sclerosis.  In March, Christina will be traveling to Bali to get her yoga teacher certification and plans to teach yoga and incorporate the yogic principles into her therapy sessions.

Physical Therapy Assistant

Robert Mark Petty, LPTA, MsT, received his Associates Degree in Physical Therapy from Northern 
Virginia Community College in 1990. After graduation, he worked at the National Rehabilitation Hospital on the Spinal Cord Unit and then on the combined Orthopedic/Neuro unit. He also worked in the therapeutic pool.

Next, he spent eight years working in sub-acute rehab centers in and around Washington D.C.   He worked briefly in home health, treating patients in their homes before starting work in orthopedics. This gave him the opportunity to also use his manual skills.

He was first trained in massage therapy in 1986 in Carrboro, North Carolina. Along the way, he  has learned techniques for working with trigger points and has also trained in reiki, watsu and waterdance, in which he holds certifications.

Mark has also studied various kinds of movement such as tai chi, yoga and also has practiced meditation for several years. He enjoys working at Physical & Massage Therapy Associates because of the friendly atmosphere, the good humor and a focus on clients which is genuine and personal.
