Josh is a very fine physical therapist. He is professional, knowledgeable and a good listener, and is encouraging. I worked with him about 18 months ago, to work on my core and posture. I knew when this new problem with my shoulder occurred that I wanted to work with him again. It has helped and it is easier to get dressed

Gail  (Patient)

For the past year, my balance (in walking and standing) has become worse. Working with Josh with use of a cane, weights and other balance exercises has improved my balance. I anticipate doing the prescribed exercises at home. My balance has improved, as well as my stiffness and bone discomfort.

Patricia  (Patient)

Severe knee problem with improvement. Josh is one of the BEST medical professionals I have ever met in my 79 years of life! He gives me – HOPE, COURAGE, & CONFIDENCE! The entire staff is EXCELLENT!

P.G.  (Patient)

I am a music teacher who besides working with teaching the piano, works with toddlers in a music program that requires a lot of moving around and kneeling on the floor to be at the kids level.  The walking on my knees caused stress on the knee joints and acute pain at times.  Through ARA’s PT program I have learned to do stretching exercises and using weights to do leg movement, which have helped increase my mobility and strengthen the muscles.  This is an awesome team of therapists!

Regina A.  (Patient)

After 10 sessions with Josh and Rebecca, I have greatly increased my mobility. They  are the best therapists I have ever worked with in my years of having psoriatic arthritis.  Everyone was kind and considerate while pushing me to my limits.

Our Staff

Allison Berger, PT, DPT

Allison grew up in Silver Spring, Maryland, and graduated from Mount Holyoke College with a Bachelor of Arts in Chemistry with a minor in Anthropology in 2014. A phenomenal patient experience led her to pursue a Doctorate in Physical Therapy, which she earned from the University of Maryland, Baltimore in 2021. Allison’s primary childhood movement practice was martial arts, where she began formally teaching both adults and children at age 11. She earned her black belt at age 14 after eight years of study and continued to teach for many years. While she entered PT school with the intention of becoming a pediatric physical therapist, Allison had the opportunity to practice in outpatient geriatrics, neurological inpatient rehabilitation, school-based physical therapy, and outpatient orthopedics. Through the course of her clinical education, Allison developed a passion for optimizing independence in older adults and assisting patients of all ages with reducing and managing chronic pain.

In treating patients, Dr. Berger formulates an individualized plan of care incorporating therapeutic exercises, neuromuscular reeducation, manual therapy, pain-relieving modalities, and patient education aimed at assisting patients in meeting their goals and learning how to best manage their conditions independently. She has a special interest in treating patients with chronic pain, balance deficits, and hypermobility syndrome. Her position as a physical therapist at Arthritis and Rehabilitation Therapy Services allows her to apply her ever-expanding base of knowledge and skills to the specialized treatment of patients with various arthritic and rheumatological conditions. She also enjoys the opportunity to develop her French and Spanish language skills when working with patients.

In her current practice, Alicia enjoys working with a wide variety of patient populations, including general orthopedics, geriatrics, and medically complex patients. She also has a special interest in working with patients with vestibular and balance disorders. Alicia strives to design individualized plans of care, utilizing manual therapy techniques, therapeutic exercise, and neuromuscular reeducation to assist patients in achieving their functional goals. Patient education remains at the forefront of her practice, as she assists and guides patients in understanding their conditions, as well as the tools and strategies needed to manage their symptoms independently. Alicia is a proponent of improving postural awareness, ergonomics, and body mechanics with each of her patients to prevent future exacerbation of symptoms and complications. 

As a certified clinical instructor, Alicia enjoys mentoring physical therapy students eager to learn and foster skills for their future profession.
