Meet Dr. Michael Danquah: The Visionary Behind RxCalculations

Michael Danquah, MS, PhD

CEO and Founder







Hi there!

I’m Dr. Michael Danquah, your go-to person for anything and everything about pharmaceutical calculations. I wear quite a few hats – I’m a drug delivery specialist, a chemical engineer, a Professor and Chair of the Department of Pharmaceutical Sciences at the Chicago State University College of Pharmacy, and last but not least, the proud CEO of RxCalculations.

If you’ve ever struggled with mastering pharmaceutical calculations or felt overwhelmed at the thought of an upcoming exam, trust me, you’re not alone! And that’s exactly why I created tools like the NAPLEX® Calculations Question Bank and the NAPLEX® calculations prep app to make calculations easier, fun, and less intimidating. In fact, I even penned down a book – “Pharmaceutical Calculations: 1001 questions with answers,” to ensure you have enough practice to ace any exam!

You might have come across my name or work on YouTube or seen us featured on channels like ABC, CBS, FOX, or NBC, but what truly makes me proud is seeing students like you gain confidence and proficiency in pharmaceutical calculations. I hold a Master’s degree in chemical engineering from the University of Kentucky, Lexington, KY, and a PhD in Pharmaceutics from The University of Tennessee Health Science Center, Memphis, TN, but my real passion lies in teaching and learning.

Apart from RxCalculations, I’ve also embarked on some exciting ventures. I am the founder and CEO of Bevinzey, an AI-powered learning platform, and Brainaly, a virtual classroom and quiz gamification software. These initiatives are close to my heart as they’re all about making learning more engaging, interactive, and enjoyable!

Why am I sharing this? Well, I want you to feel at home here at RxCalculations. Our goal is to ensure that you never have to worry about failing an exam or making a calculation error that could impact patient safety. We’re here to support, guide, and help you master pharmaceutical calculations.

I want you to remember this – RxCalculations is not just a platform, it’s a community. A community where we grow, learn, and master pharmaceutical calculations together. So, why wait? Hop on this journey with us and turn what seems like a daunting challenge into an exciting opportunity. Looking forward to seeing you on board!
