They are all top-notch. Work as a team really well. Patti helped me with a soreness in my backside. Showed me some stretches and exercises to do that helped. Three or four days, it was better. Katie saw a problem with my heart rhythm and got Patti and Marlene involved. Marlene called the doctor's office to make sure I had an appointment and told them my symptoms. I had a muscle sprain (back). Marlene helped me with that situation. They all showed concern during my time in Cardiac Rehab.
