Jonathan D. Tait, D.O.

Physician, Founder

After more than 15 years of training, and several years in practice, Dr. Tait found his true calling in medicine when he made the decision in 2013 to shift his entire practice to a Functional and Regenerative Medicine model. Since that time he has trained extensively with mentors in Functional and Regenerative Medicine. Dr. Tait uses Functional Medicine as the foundation upon which to rebuild each patient’s health. If health is restored and optimized, disease is not present. Regenerative Medicine treatments including stem cell therapy and platelet rich plasma therapy are then able to powerfully nudge the body back into balance by healing ailing and failing tissues in the body. His proprietary PRO-Mend process and unique practice combination of Functional and Regenerative Medicine has transformed the bodies and lives of more than 2000 patients since 2013. Originally from Michigan, with his wife Lisa they have made Tucson their adopted home with son Kaiden, dog Max, and cats Slim and Shady. He serves his community first as a physician, and now has expanded his reach beyond Southwest Arizona as an author, speaker, health educator and healthcare pioneer.

Dr. Tait is driven to create a ripple effect on millions of people in the United States and around the world by ushering in the much overdue evolution in how medicine and healthcare should be provided through a Functional and Regenerative Medicine model.

In 2012 Dr. Tait authored and published his first book, The Pain Free Diet.

In many cultures in the world, the oldest (and still most current form of medicine), is the food that is consumed daily.

One man’s food is another man’s poison – Lucretius

In the book Dr. Tait explains the powerful impact food can have to heal and regenerate your body, reduce or eliminate pain –  or alternatively how daily food choices can drive pain, sickness, and disease. You will learn:

  • A history of the manipulation of our food from what was once health-promoting to what is now thought to be the driving force behind a true food crisis contributing to the escalating numbers of people living with chronic pain and disease.
  • “Healthy” foods that may not be healthy when it comes to their influence on pain and degeneration of the body.
  • An exact plan, including a month’s worth of recipes, is then laid out to reboot your nutrition to decrease pain and inflammation and put your body on the path to healing.

Janet Neustedter

Front Office Coordinator, Community Outreach Liaison, Functional Medicine Health Coach, Culinary Wizard

Janet joined our team in 2016. She was raised in the Bay Area in San Jose, CA. She has been married for 30 years and has three grown children. She relocated to Tucson in 2002 with her family when her husband’s work brought them here. The transition was bumpy but she has definitely adopted Tucson as her home. She and her husband are empty nesters with two dogs to keep them busy

She attended college at San Jose State University where she studied psychology. She worked at a high end private fitness and dining club in Silicon Valley for eight years, where customer service was a priority. She has had a life-long passion for cooking and has attended many classes taught by well-known chefs and received several cooking certifications. Furthering her culinary passion, she even spent time in Washington, D.C. interning for Michele Richard in his restaurant La Citronelle

Her other passions for the outdoors, sports, and exercise “landed” her in physical therapy after a bike accident lead to a broken shoulder. The experience was another pivot point on her career path as she stayed on with the physical therapy group as a PT technician in order to help other patients mend from various injuries. She loves to exercise in all forms, is a self-professed podcast junkie, gourmet healthy cooking expert, and avid reader.

Expanding upon her passion to help coach others live an active and healthy lifestyle, she pursued an additional certification as a Functional Medicine Health Coach. In this capacity she will combine her love of fitness and healthy cooking to help our clients and patients live their healthiest and highest quality of life!
