About Us

Our Founders


Medical Director
Matt Ahern DO Medical Director Blissfusion

Dr. Ahern has been practicing medicine for over 15 years in the Emergency Room. He has held academic appointments at multiple world-class health organizations including the University of Utah, Cleveland Clinic and most recently on staff with Scripps Health. He has a passion for teaching and has trained hundreds of physicians and lectured internationally. Realizing that today’s health system isn’t focused on fitness, wellness, and prevention he expanded his interest outside of traditional medicine. He believes that infusion therapy can optimize your overall health by supplying appropriate hydration and nutrients to your body beyond what oral supplementation can provide. Outside of working in the ER he incorporates many different forms of wellness in his life including yoga, meditation, and physical activity. Dr. Ahern has trained for and completed multiple athletic events including triathlons, marathons, and ultra-marathons.


Managing Director
Tiffany Ahern Managing Director Blissfusion

Tiffany Ahern has over 20 year of business management experience.    She  has worked with multiple fortune 500 companies in different leadership roles.  Tiffany has an  undergraduate degree as well as her Masters in Human Resource Management. Her passion for people and projects became obvious as she was a successful project manager for several years.  It was during this time she realized the lack of focus employees had on health and wellness in the corporate environment. Tiffany developed this business model with the goal to make these treatments affordable and flexible for everyone’s busy lifestyle. She resides in Carlsbad, CA with her husband Dr. Ahern and 2 young girls.  In her free time she is in school for Functional Diagnostic Nutrition and enjoys traveling and staying active with her family.
