"Megan provided in home PT post op total knee replacement. She was always prompt, highly professional, knowledgeable, & observed COVID precautions as mandated at the time.


Her sweet nature, encouragement & plan of care quickly moved me from surgery to be ready for outpatient PT in a month. At outpatient PT they were surprised how well I was recovering & how advanced I was in therapy.


I can’t say enough what a delightful & productive experience Megan provided-


Highly recommend!"

“I have had the good fortune of working with Seth both as a physical therapist for an extended period before and after shoulder surgery, and then as a personal trainer.


In both roles he is extremely knowledgeable, professional and acutely attuned to the goals of the work and the limitations and strengths of the individual.


I would recommend him without hesitation.”

“I have known Seth Greiner for over six years. From the beginning of our professional relationship I have been impressed – not only with his professional competence, but also with his courtesy, and unusual understanding of my physical condition. He has a clear awareness of the exercise program that is correct for me: one that is both challenging and fun.


I look forward to our sessions and feel fortunate to have him in my life. I would happily and enthusiastically recommend Seth to any friend who needed a physical therapist or personal trainer. In my experience with him over the past two years I have found him to be both imaginative and careful: imaginative in the accuracy and sensitivity of his diagnosis and treatment, and very careful in his actual treatment program.


He continues to move a patient forward – without pushing too hard or asking unrealistic levels of success. I think any patient would be fortunate to have him. It would make me happy to recommend him.”"

“My family and I have had the great pleasure of working with Seth for more than ten years with outstanding results for lower back, rotator cuff and knee issues.


He is a true professional and I can’t recommend him highly enough for any rehabilitation assistance or for any safe and customized fitness training.”

"Greiner Physical Therapy sent Megan to our home to provide PT for my dad.


We could not have been more please with her service. She developed a great rapport with my 92 yr old dad and helped him tremendously.


Highly recommend!"

"I cannot say enough about the Greiner PT team. Seth and Megan worked out a thoughtful plan for my back, slowly increased my exercises, and changed my life."

"Seth is a fantastic physical therapist. Both my mom and dad used his company all summer long in home. Seth was exceptional. My mom has bad knees and my dad has trouble with balance and walking. Both improved this summer with his team- they both do PT all year long so they have had the good and the bad. I was so impressed with Seth my mother in law now uses him for a broken shoulder and has had amazing results.


I highly recommend Seth and his team."
