Dr. McCarthy was great! Unlike normal doctor visits, where you are in and out in 15 minutes. He listened, and really heard what ALL my concerns were not just one at a time. He made me feel at ease, and really made me feel comfortable and trusting that they would do what they can to get me healthy.


We use advanced labwork, timed to your hormone cycle to understand you better. Most clinics do not run labs, or they run inadequate labs. Our lab panels are detailed and focused.


We don’t just write prescriptions to make your symptoms go away, we work to restore your natural balance. Our prescriptions are targeted to what you actually need.


The average doctor's visit in our office is 45 minutes. At most clinics the doctor is in the room for 9 minutes or less. At Protea Medical Center we believe good, unhurried communication is essential to understanding our patients health concerns, 9 minutes is never enough.


We understand that insurance does not cover the level of care we provide. It is cheaper for them when a doctor is in the room for 7-9 minutes, writes a prescription and leaves. We know our care is valuable, but we also understand the strain of paying out of pocket for our services. We strive to make our prices affordable and reasonable.

I'm in agreement with the others, best doctor I've ever had. I love them! I met Dr. McCarthy over a year ago, and I am in a completely different place with my health thanks to him and his wonderful team.

Dr. McCarthy’s hallmark is his unorthodox approach to mental/emotional wellness and its link to hormone balance in women and men. 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, weight gain, and insomnia.
