Dr. Brendan McCarthy

Chief Medical Officer

Dr. Brendan McCarthy founded Protea Medical Center in 2006. In his role as Chief Medical Officer, Protea has grown and evolved into a dynamic medical center serving not only the Phoenix Valley, but also central Arizona.

Dr. McCarthy is the author of, Jump Off The Mood Swing, A Sane Woman’s Guide To Her Crazy Hormones. This book illustrates Dr. McCarthy’s unorthodox approach to mental/emotional wellness and its link to hormone balance in women. Through the use of blood work and clinical investigation, Dr. McCarthy gets to the bottom of possible causes for common conditions such as anxiety, PMS, depression, slow metabolism and more.

Dr. McCarthy is internationally recognized as an expert in hormone replacement therapy. He has lectured physicians and pharmacists on topics such as weight loss, infertility, hormone replacement therapy, nutritional therapy and more.
Often we look at the qualifications of a physician to help us choose a doctor, but a good doctor is more than just credentials and titles. A doctor needs to be compassionate and empathic. Dr. McCarthy has built his practice upon his dedication to each individual patient. He is passionate about his work and committed to educating his patients on their medical conditions so they can gain control of their health.

Through a growing referral network, individual patients have helped grow Protea Medical Center into the thriving practice it is today. Not through marketing programs or advertising schemes: one successful case after another has enabled Protea to achieve the position it currently holds.

Dr. McCarthy spends his free time with his wife Celeste and their three children, Liam, Aedan and Audrey. They enjoy hiking, swimming, and traveling.

Celeste McCarthy

Nutritionist / Co-Founder

Celeste McCarthy co-founded Protea with the mission to offer an integrative approach to healthcare. Recognizing the essential role good administration plays in the delivery of meaningful care, she helped develop the patient-centered coordinated care that has set Protea apart from other clinics in the field.

Celeste is a practicing Holistic Nutritionist and believes that with enough guidance and support, each patient can become an advocate for his or her own best health. Bodies are complex systems that constantly send signals. Once we learn to decode these signals, optimal wellness can be restored and maintained.

Working with our team of physicians, Celeste employs the most advanced diagnostic tools available including the InBody scale, respiratory metabolic testing, and physician directed labs to determine what nutrition plan is best suited for each patient. 

From specific dietary guidelines to reduce inflammation to safe weight loss programs to elimination diet protocols, she guides patients towards a way of eating for life rather than for a season.

Foods we eat are only one part of optimal holistic nutrition. Primary nutrition includes social, spiritual, emotional and mental health, and Celeste coaches patients to create balance in all areas of life.

Celeste is a certified yoga teacher and has been teaching in several studios throughout the valley since 2013. She believes that yoga complements and enhances whole body and emotional health.

 In her free time Celeste enjoys practicing yoga, hiking, running, reading, writing and traveling, and spending time with her husband, three teenage kids and three dogs.
