Cynthia Worden, DO, MSHPE, IFMCP

Dr. Worden received her certification in Functional Medicine through the Institute for Functional Medicine in 2016. She is board certified in Family Medicine by the American Board of Osteopathic Family Physicians, and is a Diplomate of the American Board of Integrative Medicine. She is licensed to practice medicine in the state of Oregon.

After completing her medical training in California and returning to the Northwest, she launched her medical practice in 2007 at Creekside Family Practice, practicing integrative family medicine for 10 years. Eager to focus on Functional Medicine, Dr. Worden started Bloom Functional Medicine in 2018. Functional medicine is a practice that involves an in-depth understanding of the origin, prevention and treatment of complex chronic diseases.

As a mother of two young boys, Dr. Worden has first-hand experience with the challenges many families face. She understands it can be difficult to provide healthy food for the whole family, while finding time for self-care and maintaining a healthy work-life balance. In her free time, Dr. Worden loves to spend time with family and friends, reading, skiing, kayaking, hiking, cooking and traveling.

"My vision is to be the doctor I would want for myself, my family and my closest friends. When I treat patients, I think of how I would want to be treated. I focus on prevention and early diagnosis. I view the body as an integrated and interconnected system. I know that the body has the innate capacity to heal under the right conditions. I believe that food can both heal us and harm us, and that a good diet is the foundation of good health.

I look for the root cause of illness, rather than mask symptoms with medications. I try to minimize prescription medication whenever possible, and use safer alternatives when they exist. However, prescription medications are sometimes warranted, and I will recommend them when I think they are in your best interest.

I believe that a physician-patient relationship is about partnership and collaboration, because you know your body best.

I practice what I preach. I love what I do. Most importantly, I care about you and your health." -Cynthia Worden, DO, IFMCP

Kenneth Meigs, DO

Riverside Family Practice

Dr. Meigs is a native of the northwest, having grown up on the Puget Sound. It was in high school where that he met and started dating Cindi, his wife of more than thirty-five years. After getting his undergraduate degree in Bellingham at Western Washington University, they moved to southern California to begin medical school at Western University of the Health Sciences. Residency was back north in Portland, where they had the goal to start a career, home and family. Here they have been able to feel a great pride in the raising of their three healthy young men.

Ken has been in practice in the Portland-metro area for more than twenty years as an Osteopathic Family Physician. He was the co-founder of Creekside Family Practice where Dr. Worden initially started her career. They have shared a mutual respect and are looking forward to the chance of working together again.

As an osteopath, we are taught that the body and mind are integrated. Ken’s goal is to not focus on a specific problem issue, but to treat the individual as a whole, for a more complete healing process. His additional training in Functional Medicine was a natural expansion to that base of knowledge.

As an Osteopathic Family Physician, Ken has been able to enjoy the “family aspect” of taking care of multiple generations, seeing the family dynamics and being able to know patients and their loved ones in a unique and wonderful manner. 

When not talking with patients or working on charts, Ken enjoys spending time with his family (which includes the pets), music, movies, hiking, and very often working projects around the house and yard.
