   testimonial: >-
+    I started my career as a Junior frontend developer but CSS and JS couldn't
+    get me far. That's when I found Kent. He gave me the resources I needed to
+    take my skills to a much higher level to be able to offer far more. It was
+    like years of career experience packed into just several hours and I got
+    generous help via discord or office hours when I was stuck.
+
+
+    I started freelancing by offering to build full-stack web applications for
+    people, using the most modern techniques, built from The-Epic-Stack which I
+    can confidently work with because it I studied it directly in the course!
+
+
     I refer to EpicReact.dev and EpicWeb.dev almost as much as I refer to MDN
     it's that useful.
