Meet Dr. Erik Gudmundson
Dr. Erik Gudmundson is an experienced naturopathic physician with more than 10 years of clinical experience in men’s hormone optimization and erectile dysfunction, and several years of experience in medical weight and hair restoration treatments for men. He has treated thousands of men. His biomedical-engineering background gives him a naturally analytical and systems-oriented way of thinking about human physiology. He naturally fully investigates and creates comprehensive plans with intention.
He believes it’s important to invest time into listening and building a deep doctor-patient relationship. His patients frequently describe him as calm, thorough, approachable, and easy to talk to. He believes this helps him to gather the information and build the trust needed to best help his patients. He prides himself on treating the individual rather than relying on numbers or standardized protocols alone.
Education, Training, and Clinical Experience
Dr. Gudmundson earned his Bachelor of Science in Biomedical Engineering from the University of Minnesota.
During his undergraduate training, he volunteered with the university’s Visible Heart Laboratory, an internationally recognized research laboratory that studies reanimated human hearts to evaluate pacemakers and other cardiac interventions. This early exposure to the intersection of biology, physiology, and technology helped shape the systems-based perspective he brings to medicine today.
He later earned his Doctor of Naturopathic Medicine degree from Southwest College of Naturopathic Medicine, now Sonoran University, in 2013.
Dr. Gudmundson has more than 10 years of clinical experience in men’s hormone optimization and regenerative medicine, including thousands of hormone therapy consultations since 2014.
His advanced clinical experience includes:
- Testosterone replacement therapy and hormone optimization
- Individualized dosing, symptom-based titration, and long-term monitoring
- Erectile dysfunction and sexual performance care
- Intracavernosal injection therapy, including Trimix
- Extracorporeal shockwave therapy for erectile dysfunction
- PRP procedures for erectile dysfunction
- Medical weight management and metabolic optimization
- Peptide therapies for regenerative and metabolic health
- Functional and physiology-based approaches to longevity
Her Path to Whole-Person Hormone Care
Dr. Gudmundson’s interest in medicine began with a fascination with the connection between technology and the human body.
While he was in high school in the 1990s, medical science appeared to be on the verge of major technological breakthroughs. That curiosity led him to study biomedical engineering at the University of Minnesota.
The engineering coursework was rigorous and formative—anyone who has taken biology-based thermodynamics will understand—but his perspective gradually began to evolve. He became increasingly interested in food as medicine, traditional dietary practices, prevention, and the ways less-invasive interventions might influence health long before advanced disease develops.
He began to recognize that alongside high-technology medicine was another powerful side of healthcare: one focused on understanding physiology, preventing disease when possible, and supporting the body’s natural capacity to recover and function well.
When Dr. Gudmundson learned about licensed naturopathic physicians and their scope of practice, the profession immediately resonated with him. He was drawn to the possibility of becoming an expert in minimally invasive, physiology-based medicine—using thoughtful interventions that work with the body rather than automatically relying on the most aggressive option.
He began naturopathic medical school the fall after graduating from the University of Minnesota. Today, his approach combines the systems thinking of an engineer with the individualized, whole-person perspective of a naturopathic physician.
Areas of Clinical Focus
Dr. Gudmundson’s primary clinical focus is testosterone replacement therapy (TRT), hormone optimization, erectile dysfunction, medical weight loss, and PRP hair restoration for men. Of these, he has found that TRT is often the foundation needed for men to truly thrive and enjoy their best health and life.
Hormones influence how people feel, function, and age. When hormone levels are no longer supporting healthy physiology, men may experience fatigue, brain fog, reduced motivation, changes in muscle and body composition, mood changes, low libido, and sexual dysfunction. These symptoms may appear unrelated at first and may not fit neatly into a single conventional diagnosis.
Dr. Gudmundson finds hormone optimization rewarding because thoughtful treatment can produce meaningful and measurable improvements in quality of life. He has seen appropriate treatment improve not only how men feel physically, but also how they participate in their work, relationships, families, and daily lives.
“Good hormone care is thoughtful and individualized. It’s not about chasing numbers—it’s about understanding physiology, symptoms, metabolism, and long-term safety.”
Dr. Gudmundson also provides medical weight-management care with an emphasis on metabolic health and sustainability—not merely the number on the scale. He considers body composition, hormone health, lifestyle, nutrition, and the factors that may make it difficult for a patient to achieve or maintain progress.
Sexual health and erectile dysfunction are additional areas of advanced clinical focus. Dr. Gudmundson has extensive experience evaluating men with complex or persistent erectile dysfunction, including patients who have not achieved satisfactory results with oral medications alone.
Depending on the individual, treatment options may include intracavernosal injection therapy such as Trimix, POTENTwave™ shockwave therapy, POTENTshot™ PRP treatment, hormone optimization, or a combination of approaches. He understands that discussing sexual function can feel uncomfortable and works to make these conversations straightforward, respectful, and clinically useful.
Dr. Gudmundson also has experience incorporating peptide and regenerative therapies into comprehensive plans for appropriate patients. He remains interested in emerging treatments while being candid about the difference between well-established therapies, developing evidence, and options for which important questions remain unanswered.
Why Dr. Erik Gudmundson Chose Full Potential HRT Clinic
Before joining Full Potential, Dr. Gudmundson worked in clinics dedicated to men’s hormone therapy and regenerative medicine. His clinical work focused primarily on hormone optimization, sexual health, and advanced treatments for erectile dysfunction.
He chose Full Potential because of the clinic’s emphasis on high-quality, ethical, patient-centered care.
Hormone medicine can vary considerably from one clinic to another. Dr. Gudmundson wanted to practice in an environment that prioritizes proper evaluation, individualized dosing, careful monitoring, and long-term follow-up rather than rushed, high-volume medicine.
He also values practicing within a collaborative medical team. At Full Potential, physicians consult with one another, share clinical experience, continue learning, and work within common standards while still individualizing treatment for each patient.
That environment allows Dr. Gudmundson to practice in a way that aligns with his values: thoughtfully, carefully, and with attention to both meaningful results and long-term health.
How Dr. Erik Gudmundson Approaches Patient Care
Patients often describe Dr. Gudmundson as calm, thorough, and easy to talk to.
He takes listening seriously. Many patients come to him after feeling rushed, dismissed, or unheard elsewhere. Before recommending treatment, he works to understand the full picture—including symptoms, laboratory findings, medical history, lifestyle, goals, stressors, previous treatments, and concerns.
Dr. Gudmundson is pragmatic and evidence-informed. He is open to new and emerging therapies, but he does not assume that newer automatically means better. He believes patients deserve an honest explanation of what is well established, what remains uncertain, and what makes sense for their individual circumstances.
“I’m open to new and emerging therapies, but I also believe in being honest about what we know, what we don’t know yet, and what makes sense for each individual.”
He also adjusts his communication style to the person in front of him. Some patients prefer a focused, businesslike visit. Others appreciate more conversation and time to build rapport. Dr. Gudmundson pays attention to those preferences and tries to meet each patient where they are.
At the core of his approach is a genuine desire to help patients feel and function better over the long term—not simply improve a laboratory number or produce temporary symptom relief.
Dr. Gudmundson works especially well with patients who want a thoughtful, data-driven, individualized approach and who value long-term health as much as short-term improvement.
Outside the Clinic
Outside the clinic, Dr. Gudmundson enjoys spending time with his family, hiking, identifying plants, occasional rock climbing, reading fantasy novels, and taking on hands-on DIY projects.
His engineering side remains evident in his curiosity about how things work. Past projects have included rebuilding the battery of a hybrid vehicle, while his longer-term interests have included learning to sail, trying blacksmithing, and eventually building a kit car.
