Malcolm Rosenberg, RN

About The Author

Malcolm Rosenberg, RN began his career as a nurse and nurse educator after receiving his Associates Degree from Broward Community College in 1989. He has worked in many medical and surgical areas including orthopedic, telemetry, oncology, as well as the ICU, recovery and emergency rooms.
Prior to becoming a nurse, Malcolm was trained as a mechanical engineer and worked for 10 years in aircraft design and manufacturing. In that setting he began to appreciate the value of using simple diagrams and cartoons to learn and communicate complex dynamic processes.

That learning was put to use when Malcolm was asked to teach continuing education courses for hospital nurses. He decided to create these courses primarily through the use of simple sketches and a light-hearted approach to learning.

Since he wanted his students to understand the content without being overly concerned with note taking, he put together handouts for the students of exactly what was on the overhead projector. Those packages then became these books.

Malcolm Rosenberg lives in Florida with Sandy, his adoring wife, Sandy’s mom, Flo, their son, Alex, two dogs and three cats. His older son Craig lives in Georgia with his wife Tara.

They are so simple they make you wonder what was so difficult to understand in the first place. No nonsense, no frills, and to the point. What other books do you have?

I believe your books are some of the best I have reviewed in my 27 years in nursing. They deliver complex information in conversational language that keeps learning effective but makes it fun and easy.

I hope nurses at all levels will buy and work through your publications. I especially like “Drug Calculations for Nurses Who Hate Numbers” because it removes the struggle from so many calculations whether one is a student or has achieved years of practice.

Thank you for sending me your drug calculations book. I believe it will be quite helpful. My test is in three days! My daughter is starting the metric system in school and asked if she could use it.

PS: I should be the president of Nurses Who Hate Numbers!

I am a 43 year-old nursing student. I have recently seen a copy of your book on Drug Calculations and to me it is the greatest thing since “sliced bread!” Your book has made it easy for me to understand. Thank you for a great book!

Enclosed please find a check for three copies of your math book entitled “Drug Calculations for Nurses Who Hate Numbers.” One of my classmates ordered your book and most of us are very impressed by it so please ship my three copies as soon as you can. Thank you very much!

PS: Our math instructor really loved the book. We need all the help we can get…but you already know that.
