Meet Dr. Matthew Renshaw Ruddell
Dr. Matthew is a diligent, attentive, and compassionate naturopathic physician with a strong foundation in primary care and meaningful experience in testosterone replacement therapy, medical weight loss, sexual health, and whole-person medicine.
He is known for his attention to detail, responsiveness, and willingness to take the time necessary to understand what a patient is experiencing. Dr. Renshaw Ruddell values the quality of the doctor-patient relationship and wants every patient to feel seen, heard, and actively involved in decisions about their care.
Patient education is also central to how he practices. Rather than simply telling patients what to do, he helps them understand their health, their treatment options, and the steps they can take to improve their long-term well-being.
Education, Training, and Clinical Experience
Dr. Renshaw Ruddell graduated cum laude from Western Washington University in 2012 with a Bachelor of Science in Biology. He also completed a minor in Spanish and studied microbiology in Chile.
Following college, he served in the United States Army Infantry from 2013 through 2016. He continued his military service in the Oregon Army National Guard from 2016 through 2019 while attending naturopathic medical school.
Dr. Renshaw Ruddell earned his Doctor of Naturopathic Medicine degree from the National University of Natural Medicine in 2020. He then completed a two-year, CNME-certified residency in naturopathic primary care at Canby Clinic from 2021 through 2023.
His background includes:
- Naturopathic primary care
- Testosterone replacement therapy and hormone optimization
- Medical weight management
- Sexual health and performance care
- Nutritional counseling
- Botanical and supplement-based treatment
- Lifestyle medicine
- Whole-person support during illness and recovery
- Helping patients communicate and advocate for themselves with outside healthcare providers
His primary-care residency gave him extensive experience evaluating complex concerns, recognizing connections among different symptoms, and considering the patient’s complete health picture rather than focusing on one diagnosis or laboratory result alone.
His Path to Whole-Person Hormone Care
Dr. Matthew’s path to medicine began with his own health journey.
He spent much of his teenage years chronically ill and learned firsthand how profoundly poor health can affect every part of life. Through sound nutrition, regular exercise, and meaningful lifestyle changes, he experienced a transformation in his own well-being.
That experience taught him that without health, it can be difficult to remain present, enjoy life, and participate fully in the things that matter most.
“After seeing my own life transformed through nutrition, exercise, and lifestyle modification, I wanted to help other people change the trajectory of their health—because with health, people can change their lives.”
This personal experience drew him toward naturopathic medicine and its emphasis on understanding the foundations of health, addressing contributing factors, and helping patients build greater resilience rather than managing symptoms alone.
It continues to shape his approach today. Dr. Matthew wants patients to understand that their current health does not necessarily have to define their future—and that the right combination of medical treatment, education, and daily habits can create meaningful change.
Areas of Clinical Focus
During medical school and his primary-care residency, Dr. Matthew worked hard to help patients using the tools of naturopathic and primary-care medicine. However, he frequently encountered patients who continued to struggle with chronic, suboptimal health. They were managing to get through life, but they were not truly thriving.
After residency, he trained with Dr. Robert Strait and the Full Potential physician team in testosterone replacement therapy, medical weight loss, and sexual health and performance care. He was struck by the clear changes he began seeing in appropriately selected patients—particularly men who had struggled with fatigue, reduced motivation, unfavorable changes in body composition, low libido, and sexual dysfunction.
When it comes to testosterone replacement therapy, he considers symptoms, laboratory findings, treatment response, medical history, lifestyle, and long-term health—not simply whether a testosterone result falls inside a laboratory reference range. He understands that successful treatment may require careful observation and adjustment over time.
When it comes to medical weight loss, using medications such as tirzepatide and semaglutide, he considers nutrition, movement, sleep, stress, metabolic health, hormone health, and the practical challenges that may be preventing a patient from making sustainable progress.
When it comes to men’s sexual health, he approaches these concerns carefully and respectfully. He understands that sexual health can be difficult to discuss and works to create an environment where patients can speak openly without embarrassment or judgment.
As one of the more senior physicians at Full Potential, he also brings meaningful clinical experience and a growth mindset to Full Potential. He is continually looking for ways to improve how treatment is evaluated, communicated, and individualized.
Why Dr. Matthew Renshaw Ruddel Chose Full Potential HRT Clinic
After completing his primary-care residency, Dr. Matthew trained with Dr. Robert Strait and Full Potential’s team of experienced hormone physicians.
That experience allowed him to combine his broad foundation in naturopathic and primary-care medicine with more focused training in testosterone replacement therapy, medical weight management, and sexual health.
He was especially drawn to the opportunity to provide care that could produce clear and meaningful improvements in patients’ daily lives. He saw men regain energy, motivation, sexual function, and the ability to participate more fully in their families, work, relationships, and interests.
Full Potential also gives him the opportunity to practice within a focused medical team while continuing to bring his broader knowledge of nutrition, lifestyle, supplements, recovery, and whole-person health into the care he provides.
The environment supports one of his most important professional values: continual growth. Dr. Renshaw Ruddell is a keen observer who is always looking for ways to deepen his knowledge and improve how he serves his patients.
How Dr. Matthew Approaches Patient Care
Dr. Matthew takes his responsibility to improve his patients’ health very seriously.
He listens carefully, asks detailed questions, and works to understand what the patient has experienced—not simply what appears in the medical record. His empathic nature helps patients feel comfortable discussing concerns they may not have felt able to address elsewhere.
He also believes patients deserve to understand their own healthcare. He explains the reasoning behind his recommendations, teaches patients about their health, welcomes questions, and encourages them to participate actively in decisions.
His approach is both holistic and practical. In addition to managing TRT, medical weight loss, or sexual health concerns, he may offer supportive guidance involving:
- Nutrition and lifestyle
- Sleep, exercise, and recovery
- Targeted supplementation
- Preparation for or recovery from illness and medical procedures
- Questions to discuss with outside healthcare providers
- Strategies for becoming a more informed advocate for one’s own health
Dr. Matthew recognizes the limits of any one clinic or physician. When patients need care from another medical professional, he helps them better understand the situation and communicate their concerns effectively.
He works especially well with patients who want a detailed, thoughtful relationship with their physician and who value education, responsiveness, whole-person care, and active participation in their treatment.
“I care deeply about people and their lives. I want patients to feel seen and heard, understand their health, and know that I take the responsibility of elevating their health seriously.”
Outside the Clinic
Dr. Matthew is grounded by what he describes as faith, family, and foundations.
Outside the clinic, he values time with his wife, son, and daughter, caring for his homestead and animals, and being outdoors. His interests include hiking in the Mount Hood National Forest, backpacking, camping, fishing, skiing, and snowboarding.
His military service and broad range of work and life experiences have also helped him relate to patients from many different backgrounds. He understands that each person brings a different history, set of responsibilities, and definition of what better health would make possible.
At the core of his life and medical practice is the belief that health reflects the story of a person’s life—and that with knowledge, support, and consistent effort, that story can change.
