“Dr. O’Neil is one of the few people in the medical profession who truly cares about her patients. Her methods of testing, in addition to her evaluation and explanation of the diagnosis, gives you a level of confidence that you are getting the best treatment possible from the best doctor. She diagnosed my early prostate cancer and helped me to a record recovery. In 2023, she detected a major heart problem. Again, I made a remarkable recovery — so much so the cardiologist is still baffled. Dr. O'Neil is a great person. No doubt.”

-Patient, 64-year-old Male

“I’ve struggled with gut issues for over half of my life. I’ve seen many doctors within the Northeast with the hopes of treating this issue beyond dietary restrictions and colonoscopies. Within a season of working with Dr. O’Neil, I noticed a shift in mental clarity, metabolism, and food tolerance. I highly recommend her for gut and stomach problems.”

-Patient, 27-year-old Female

“I work full-time as a data analyst at a major corporation. This summer, I spent a week in Colorado hiking up peaks of 6,500, 8,600, and 11,300 feet. Every year, I go mountain biking with my son in Arizona. My marriage of 45 years is still as strong and loving as ever. I don't have any prostate issues, arthritis, or aches and pains. I don't take naps. I don't drink coffee. I sleep well, and I have energy all day long. What is my secret? I listen to Dr. Kathleen and follow her advice. She blends years of experience with an understanding of cutting-edge research, to come up with practical solutions that heal and strengthen. Diet, exercise, hydration, supplements, hormones, herbals, electrolytes, biomechanics. Her toolkit is vast and always expanding. But the key is that she listens to each one of us in depth and crafts creative recommendations that fit our unique lives. She understands what we need to build wellness and explains so clearly how it all works. And she does it with wonderful enthusiasm and warmth.”

-Patient, 75-year-old Male

“Post military service, I struggled with cardiac, endocrine, brain, and nervous system issues from a severe traumatic brain injury. With Dr. O’Neil’s care, I was able to identify and treat each issue. For all things wellness, Dr O’Neil is the only person you need to speak to. She will not let you down.”

-Patient, 34-year-old Female
