Before joining our team, Dana was a patient of Dr. McMonagle’s. She had a long history of chronic illness and extreme fatigue. For many years she was undiagnosed and very ill. At her first appointment, with coverage from her insurance, we were able to run several lab tests. Based on those results and a thorough history, we created a new treatment plan for her. This included our highly sought after Ozone treatments. Ozone was life changing for her. She began to regain energy, mental clarity and function after her first treatment. She is forever grateful for the team at Lake Oswego Health Center for restoring her health and giving her the opportunity for a normal life again.
Dana is very excited to join us here at Lake Oswego Health Center. She has a passion for helping people and is excited to get to know all of our wonderful patients.
