I agree that you should write something in your “About Me” section. It gives people insight about your personality and training philosophy and makes your profile a little more personal.
Also, here are a few other ideas for you:
–Professional pictures or headshot
–Gather testimonials from clients
–Start a blog
–Professional certifications and specialties/CPR are a must, so continue to strengthen your profile this way–through education.
Some of this comes with time, and you can add to it slowly to build your profile.
