MEET YOUR INSTRUCTOR
34+ Years of Experience. A Passion for Teaching.
Kimberly Colwell-Walter, Founder & Lead Instructor With more than 34 years of hands-on hospital experience in cardiac monitoring and EKG rhythm interpretation, Kim brings real-world clinical experience into every class she teaches. Throughout her career, she has interpreted cardiac rhythms, trained and mentored monitor technicians, developed educational materials and workflows, and helped healthcare professionals strengthen their rhythm-recognition skills. Kim currently teaches EKG and rhythm interpretation at a local college and has a nursing education background from St. Petersburg College, along with specialized education in EKG interpretation and medical terminology. Her approach is simple: students shouldn't just memorize what a rhythm looks like—they should understand why it looks that way and what is happening in the heart. “EKG interpretation shouldn’t be memorized. It should be understood.”
About
Colwell Cardiac Academy provides practical, in-person instruction in basic EKG interpretation and cardiac rhythm recognition. Classes are personally taught by founder and lead instructor Kimberly Colwell-Walter, who brings more than 34 years of hands-on experience interpreting cardiac rhythms in a hospital setting, as well as experience teaching EKG and rhythm interpretation at a local college.
Our goal is to make rhythm interpretation easier to understand by teaching the reasoning behind what appears on the monitor—not simply asking students to memorize rhythm strips.
Classes are designed for nurses preparing for annual competencies, nursing students, graduates preparing for the NCLEX-RN or NCLEX-PN, healthcare professionals who want to strengthen their skills, and individuals interested in becoming EKG or cardiac monitor technicians.
We offer one-on-one tutoring, private instruction, small-group classes, and larger classes for colleges, nursing programs, healthcare facilities, and other organizations. Instruction includes clear explanations, hands-on rhythm practice, educational worksheets, practice strips, and practical tools that help students build confidence and apply what they learn.
