Client Experiences



After experiencing a 2nd chance at life I embraced a new regime lead by Dr Speck and POTENTRx I was indeed fortunate to be saved by Seattles finest paramedics and Harbor View/UW ER after a few heart shocks. Now I really understand the importance - absolute necessity, of daily excercise and changing your diet. I have had way more success on the former vs the latter. Thanks to POTENTRx testing and Dr Speck and staff consultation to establish my optimum level of exercise performance and helping me better understand this cardio physiology. I like your ease of access/parking as well as your proximity to my other health care providers at Swedish and Polyclinic. Your PT and exercise equipment and your staff are the best!



POTENTRx and Dr. Speck’s practice is a dynamite combination, with its focus on providing optimal exercise regimens for living healthfully. Of great value to me is learning that I don’t need to engage in extreme sports to get maximum benefit. The heart rate that burns fat most efficiently for me, as determined by POTENTRx measurements, is not as high as I would have thought. Working with the exercise physiologist has been a delight. She has been inventive in customizing exercise regimens for both home and travel.

I am an ACSM certified exercise physiologist and have worked in cardiac rehab/wellness for the past 19 years.  I have always been pretty active and have worked to incorporate exercise in to my weekly routine.  Last year I turned 40 and wanted to prove to myself that I could do something I had not yet done in life. I trained for and ran a half marathon. I did find myself in somewhat better running shape. However I also found that my cholesterol levels were not within the guidelines. Due to my family history of dyslipidemia, I was concerned about this.

I turned to Potentrx for guidance on how to best exercise to lower my cholesterol and to get in to better shape. Despite my best efforts on my own, my results had not been what I wanted. I met with the kind and professional staff at Potentrx. They worked with me to develop my personalized exercise plan. This plan is based upon the results of the extensive testing I did with them.  The exercise physiologists there helped to come up with an exercise routine which I can fit in to my family, work, and ferry commute schedule. They were great at answering my questions and discussing the results of each test with me.

I am very appreciative of the kindness and care I have been shown at Potentrx. From the scheduling of the appointments, to checking in, to the actual appointments and testing, each staff member did their best to make me feel welcome. Whether one’s exercise goal is performance or health related, I would highly recommend Potentrx. It is individualized and it works. Thank you Potentrx!
