Colorado Cardiac CPR provides certification and recertification in BLS (Basic Life Support), First Aid, Heartsaver CPR/AED, ACLS (Advanced Cardiac Life Support), PALS (Pediatric Advanced Life Support), CPR (Cardiopulmonary Resuscitation), and AED (Automated External Defibrillator) use.

Since Colorado Cardiac was founded by Tim Snyder in 2013 we have served the Littleton area, the city of Denver and its 9 surrounding counties as a designated American Heart Association (AHA) training site certifying over 5,000 people in different disciplines at one of our 3 different locations as well as on-site training.

Tim Snyder served in the U.S. Marine Corps from 2003-2007. He later started Cardiac CPR and First Aid Training which he has been in operation for 5 years. Tim is also an EMT instructor at Arapahoe Community College and has been working at Northglenn Ambulance as a paramedic for the past 3 years.

Ron got his start in Fire/EMS in northern Virginia as a volunteer firefighter/EMT and an EMT/Dispatcher.  He earned his Paramedic certication in 2007, when he then relocated to the beautiful Rocky Mountains. He has worked at local agencies as an Emergency Medical Dispatcher, Paramedic, CPR Instructor, and  as an Air Medical Communications Specialist at Airlife Denver. In 2017 Ron graduated with honors from Nursing school whit his BSN. He currently works at Porter Hospital on the Ortho-Spine floor and at Medical Center of Aurora in the ICU.

Ron believes we can save more lives by putting CPR in every home. He became an ACLS and PALS instructor in 2013 and Training Center Faculty with Denver Health Training Center in 2017. During nursing school Ron and his wife decided to merge with colleague Tim Snyder at Colorado Cardiac CPR due to the increasing demands of his growing business and the arrival of twin boys. He and his wife, Jackie, also have a 4 year old girl and reside in Parker, Co. Ron continues to work as an Registered Nurse and flights dispatcher, while maintaining his passion for teaching life saving skills.

Meet Our Friendly Staff:


Olivia "Liv" Mucha - Lead Instructor

I love being in the medical industry! As well as being a CPR instructor I am also a Wilderness First Responder and finishing my EMT. I enjoy teaching and sharing my passion for learning with everyone. When I'm not teaching I enjoy backpacking, camping or doing yoga pretty much anything that will keep me outdoors. I also hate wearing shoes, so don't be surprised if you meet me and I am barefoot


Mary Oulliber - Office Extraordinaire

I have a love for all things outdoors, whether its hiking, camping, or riding my horses, I love to be outside. My true passion lies in my love of horses, I have been riding horses since I was 3 years old and have 2 horses of my own. Along with horses I love the rodeo and even spent a few years as a Rodeo queen. I am excited to be a part of the amazing team here at Colorado Cardiac as the office manager and look forward to gaining some new skills to become an instructor.


Murphy - Senior Barketing Manager

I tend to think of myself as a one man wolf pack. I love chewing on my favorite toy and farting while I take frequent naps. Sometimes life as a puppers is difficult but the frequent walks make up for it.   So many new smells! My role model when i grow up is Sherlock Bones.


Sean Huft

Well hey! My name is Sean and I'm one of the instructors here. I love teaching CPR part time on top of my night job as an EMT at a local ambulance company. When I'm not teaching CPR or on shift, you'll usually find me outdoors. In the summer, I enjoy long walks up a 14er, sunrise morning fly fishing on a river, and cycling with my family.  In the winter time, I chill out a little bit, but still try and get outside to go snowshoeing or hunting.

I’ve been teaching AHA courses for over 9 years and as a nurse my experience has been working in critical care. My goal as an instructor is to have students leave a class with more knowledge, confidence AND to hear them say they actually enjoyed it! Life is too short to not make things enjoyable. Besides teaching, the things I enjoy are the Colorado trifecta of hiking, biking and skiing with family and friends. Hope we meet soon!

I love living in Colorado! There are so many things to do that my list seems to be getting longer instead of shorter as the time gets on. Outside of teaching classes you can find me biking, hiking, or trying out a new recipe. I also love the healthcare profession. I've been working in healthcare for the past 9 years starting as a CNA and now as a paramedic.

In addition to possibly being your BLS or First Aid instructor, I am a general outdoor enthusiast and excitement hound. I spent a lot of years rock climbing -- across 7 states and 2 countries! I work for 5 months a year as a fly fishing guide at a remote lodge in Alaska and in the off season I hang around the Denver EMS world, I am a state and nationally registered EMT as well as an AHA endorsed BLS, First Aid, and Heartsaver instructor. I love teaching and I really enjoy all of the cool people I get to meet doing it. Especially in the medical profession as I find we are, all of us peas from a little bit different of a pod.

My passion for the great outdoors keeps me busy biking mountain passes and trails, skiing fresh powder and hiking in the backcountry. I am a teacher in the metro area's public schools and support students with learning disabilities. As an EMT, I enjoy working the medical tent at festivals and races, leading backpacking trips with students and teaching for Colorado Cardiac!
