She earned her 4-year doctorate degree in Naturopathic Medicine at National University of Health Sciences in Illinois, one of seven accredited naturopathic medical schools in North America. Her clinical rotations included special training in the benefits of fasting to heal chronic illnesses as well as gastrointestinal health and chronic disease.

She takes the time to listen and understand each patient’s unique condition in order to create a personalized treatment plan and treat by addressing the whole body. Her goal is to heal, teach and inspire each person to be an advocate for his or her own health.

Dr. Alioto has a special passion for helping people reach an optimal level of health, working with patients of all ages, including infants.

She grew up in Northern California with her parents and older sister. She swam and played volleyball competitively in high school and has always had a passion for being healthy and active. The medical world and caring for others had always intrigued her, however, throughout high school and college she struggled with severe stomachaches and weight loss that, despite all the testing, no medical doctor could figure out. Through her setback, she was inspired to find a more individualized and wholesome way of healing. This experience led her to Naturopathic Medicine, which soon became her passion.

Dr. Alioto is excited to be back in her home state after practicing Naturopathic Medicine in Minnesota for 2 years.

David M. Downey

Director of Operations & Fitness Programs

David received a Bachelor of Science in Communication, with Minors in Business Administration and Spanish from the University of Arizona in Tucson, Arizona in 2004. He is the Owner and Head Coach of OPEX Santa Barbara, as well as the acting Director of Operations & Fitness Programs for Regenerate Health Medical Center.

He has an extensive background in business coupled with a drive and passion for fitness. This fueled his aspirations to open a world class training facility, where the client, not a methodology, dictated the design of the fitness program. He is a certified OPEX CCP Level 1 Coach (NASM accredited) and a certified USAW Sports Performance Coach. He has been in the health and fitness industry for over a decade as a coach and business owner.

David has taken an active role in his health since 2005 when his fitness journey began doing bootcamps. As he evolved, he was transfixed, as many others have been, into being a CrossFit trainer. Realizing, after a few years, the lack of sustainability within this style of training, he was determined to find a better way to train and to coach. OPEX Fitness, founded by James Fitzgerald, created an opportunity to learn the how’s and why’s behind program design, nutrition, assessment and what it meant to truly become a professional coach. Through that learning, OPEX Santa Barbara was born to help people create longevity in their lives with whatever THEY wanted to accomplish.

He continues to this day to be coached by his mentor, OPEX HQ Head Coach, Michael Bann. Together they continue to refine and adjust his training to ensure that with his busy lifestyle, he is still able to make progress. David takes this same approach to each and every one of his clients.

David believes in using a combination of movement, nutrition and lifestyle management, to live a pain free and active lifestyle. He intelligently designs fitness programs based on your individual needs and health conditions. For him, fitness is more than just working out, it bleeds into all aspects of living, bringing a sense accomplishment, determination and desire to live a larger life. Setting goals and using the medium of fitness to increase and maintain a high quality of life for his clients drives his passion as a professional coach and mentor.

David’s mission is clear, to deliver his clients the highest quality results, through professional coaching, education and commitment to treating each client as the unique individual that they are.
