Dr. Ferguson was born and raised in South Africa. He earned a bachelor’s degree and medical degree from University of Cape Town in South Africa. He then completed his residency in Internal Medicine and fellowship in Cardiology and Electrophysiology at Oxford Radcliffe Hospitals in Oxford, England. While in Oxford, Dr. Ferguson also did a two year Medical Doctorate research degree investigating cardiac pacing. Following this, he moved to the United States and completed an additional Electrophysiology fellowship at the University of Virginia. During his time at UVA he was promoted to Professor of Medicine, with an endowed Chair and was Director of Clinical Electrophysiology for 5 years.

“I strive together with my colleagues to provide compassionate, efficient and excellent clinical care for all my patients.”

Dr. Ferguson’s training and research is in clinical electrophysiology. Most of his patients have abnormal heart rhythms and typically have symptoms of palpitations, racing heart beats, dizziness, blackouts, shortness of breath or fatigue. These symptoms may represent slow, fast or irregular heart rhythms. These abnormal rhythms can be treated with medications, pacemakers or implantable defibrillators or a procedure called catheter ablation. He is experienced in all supraventricular and ventricular arrhythmia ablation including epicardial techniques and does all sorts of cardiac device implants. He has a particular interest in atrial fibrillation ablation using non-fluoroscopic techniques and mapping of ventricular tachycardia.

When he is not at work, Dr. Ferguson enjoys biking, skiing, hiking, reading and traveling all over the world with his wife and two sons. They are excited to explore all that the Colorado outdoors has to offer.

*Dr. Ferguson was very attentive, did a great job explaining things.


It was my first in-person meeting with the doctor. He was incredibly empathetic and patient with my many questions.


Dr. John Ferguson was very attentive and informed me of my condition and options for correcting it. He has a great patient manner.


overall good experience


I really appreciate *Dr. Ferguson. Always thorough, always kind.


great job


Dr. Ferguson probably has saved my life with the procedure he did on me. I feel great! EKG is normal. Echo is normal!


I get the coronavirus precautions, but he never once listened to my heart yet expected me to just dance in for a surgery when I clearly had/have significant anxiety, lots of questions and concerns. He did not seems to care about or share my concerns, and I felt like I was bothering him and that my concerns were beneath him. I get that he is a great practitioner, but his detachment from the emotional side of the equation does not foster trust or engender confidence.




We liked and trusted our new Dr. Ferguson immediately.
