This guy deserves a Noble Prize for teaching!!!

Dr.. Campbell, thank you again for your videos. You have an uncanny ability to communicate complex subjects in an understandable, well-organized and sensible manner. Although I am enrolled in nursing school in the USA, I regularly watch your videos to help me understand the subjects assigned. I find your use of analogies to be particularly useful to my retention of the information that you share. Best wishes from across the pond with sincere thanks.

we need this kind of proffessors

Such a great teacher, thankyou Dr. Campbell for making things easy 🙏

You are such a good teacher. Thank you fot the time and effort to make these videos. They are really helping so much.

It's amazing how much more clearly you explain A&P than my instructors. Thank you.

Dr. Campbell, You are an amazing teacher. I learned more about the heart in your presentations than i did by reading my textbook. Your explanations and illustrations make everything easier to understand. Thank you for giving me the confidence i needed to continue my education at 52!!!!!

One of the greatest teacher I have encounter in my life, never been thankful to present technology that i was able to come across to this wonderful man,, taking so much effort with this kind of content. Thank you so much Dr John Campbell! ❤ ... and may the Lord continue to bless you.

Dr. Campbell what a wonderful gift of teaching you have, I would never thank you enough for helping me in the process of preparing my self for NBDE part 1. You make everything so well understanding in an easy way. I appreciate you very much. Best wishes!

I have been preparing myself for an interview and your videos are helping me to find out what I want to learn.

I'll be following your tutorials. Very helpful. Thank you for your way of teaching. All the best.

Perfect timing to have found your simply terrific presentation. It's like my mind had gone blank from nonusage of medical terminology, biology, physics, chemistry and math courses over the years of ongoing academic skillsets. My cobwebs have been brushed away. It's time for refreshing videos as you have done to reinforce, purge, update and advance my prior knowledge. I do thank you so very much for helping me recall clouded information that I am beginning to remember. YOU'RE AWESOME! Your friend....DEVEREE

Thank you! I am a nursing student and the lecture slides that I am trying to learn from are not very explanatory. Thank you for making your lectures interesting and understandable.

Thank you!

Thank you for this informative video. I appreciate your efforts. Your explanation is very easy to understand. Thanks for sharing

I like your videos! I understand easily. Thank you so much.

Thanks for the video. These are all very interesting. I follow you because of covid 19 mainly but I enjoy learning medical related topics. Part of my motivation is eating a diet called the whole food-plant based diet. My total cholesterol was just getting high after I eliminated sugar. I eliminated sugar because of some videos on KZfaq about it's danger, namely Robert Lustig. I researched more information and found the whole food-plant based diet which lowered my total cholesterol from 210 mg/dl to 135 in just a few weeks. It also allowed me, wit doctor supervision, to stop using blood pressure medication. That was a beta blocker that controlled a high heart rate. My heart rate is now normal. All that time and I thought anxiety had caused my high heart rate. I also lost 50 lb. Still down about 40 and still healthy 3 years later.

You are good Sir, thank you so much 🙏

Sir, you are just amazing
