SWIFT Wart Treatment in Laguna Woods, CA
Treat Persistent Warts Without Cutting, Freezing, or Acids
SWIFT uses controlled microwave energy to activate your body’s natural immune response and treat eligible plantar and common warts.
Are You Dealing With Any of These?
- A painful wart on the bottom of your foot
- A wart that keeps returning after treatment
- Several warts growing close together
- Discomfort when standing, walking, or exercising
- A wart that has become larger or more noticeable
- A stubborn wart that has not responded to home treatment
What Can SWIFT Wart Treatment Help Treat?
SWIFT may be considered for several types of persistent warts affecting the feet.
Plantar Warts
Plantar warts develop on weight-bearing areas and may cause discomfort while standing, walking, or exercising.
Mosaic Warts
Mosaic warts form in clusters and can cover a larger area on the bottom of the foot.
Recurring Warts
SWIFT may be considered when a wart returns after freezing, topical medication, or another previous treatment.
Multiple Warts
Several nearby warts may be evaluated to determine whether SWIFT is an appropriate treatment option.
Not every skin growth is a wart. Dr. Petersen will evaluate the area and confirm the diagnosis before recommending treatment.
Help Your Body Recognize and Fight the Wart
Warts are caused by certain strains of the human papillomavirus, or HPV, which can avoid detection by the immune system. SWIFT delivers controlled microwave energy to the affected tissue, creating a localized immune response. This helps your body recognize and respond to the virus rather than simply removing the wart’s visible surface.
Benefits of SWIFT Wart Treatment
No Cutting
SWIFT does not require surgical removal or incisions.
No Freezing or Acids
Treatment does not rely on liquid nitrogen or topical acids.
No Dressings
SWIFT generally does not create an open wound requiring bandages.
Minimal Activity Disruption
Most patients can return to their regular activities after treatment.
SWIFT provides a targeted approach designed to treat eligible warts without damaging the surrounding skin.
How Does SWIFT Wart Treatment Work?
The SWIFT applicator delivers controlled microwave energy directly to the wart for a few seconds. This energy creates a localized response that alerts the immune system to the virus responsible for the wart. The immune response continues after the appointment as the body works to clear the affected tissue.
What Is SWIFT Treatment Like?
1. Evaluate
Dr. Petersen examines the area, confirms whether it is a wart, and determines if SWIFT is appropriate.
2. Treat
The applicator delivers brief doses of controlled microwave energy directly to the affected tissue.
3. Return to Your Day
No bandage is generally required, and most patients can resume their usual daily activities after treatment.

Review of Dr. David Peterson, Podiatrist Before I begin, I want to make it clear that I receive no compensation, discount, or special treatment from Dr. Peterson or his office because of this review. He did not ask or suggest that I write it. I am sharing my experience because I genuinely believe it may be helpful to others. I have been a patient of Dr. David Peterson for more than four years. I wear orthotics, and he has also treated me for a painful nail spike on my big toe. As a podiatrist, I have always found him to be knowledgeable, professional, and outstanding. However, this review is primarily about my experience with EMTT (Extracorporeal Magneto Transduction Technology). I had been curious about EMTT and wondered whether it was simply another promising treatment that would eventually fade away after a short period of time. I had originally considered trying it for my knees. Then, in August 2026, I severely injured my lower back for no obvious reason. I began experiencing intense spasms in my lower back, around belt level and just to the right of my spine. I wasn't sure whether the problem was muscular or nerve-related. What I did know was that the pain was severe—about a 9 out of 10. I had difficulty walking and was experiencing four or five severe spasms every hour. The spasms would suddenly grab me and send sharp pain down the back of my right leg, making even simple activities extremely difficult, including getting in and out of bed, walking, or standing up from a chair. Dr. Peterson suggested that I try three EMTT treatments, one week apart. After my first treatment, I felt a significant improvement. I was able to walk without triggering spasms, and the frequency of the spasms dropped dramatically—from four or five an hour to only three during the following 24 hours. Wearing a back brace also helped improve my comfort level. Interestingly, during the EMTT treatment itself, I felt very little. I didn't feel an electrical sensation, vibration, heat, or much of anything else. In fact, I remember thinking that perhaps it wasn't going to help me at all. I completed all three treatments, one week apart. EMTT is not covered by my insurance, and I was very skeptical about whether it would be worth the expense. However, after completing the three treatments, I became convinced that EMTT had been extremely helpful and had provided me with significant and lasting relief. I was eventually able to see a spine specialist and have an MRI performed to further evaluate my back. I understand that EMTT is not necessarily the answer for every condition, and I can only speak from my own experience. But based on what I personally went through, I am convinced that Dr. Peterson did everything he could to help me, and that EMTT played an important role in getting me through an extremely painful period. I am very grateful for Dr. Peterson's care, professionalism, and willingness to try something that I initially viewed with a great deal of skepticism. For me, the results were very real, and I would strongly recommend Dr. Peterson to anyone considering his care.![]()

After my existing Dr. was in an accident, I had to find new care. I saw two other podiatrists before deciding to transfer my care to Dr. Petersen & his outstanding team at Pacific Foot & Ankle. I have not looked back since and know I found the right Dr. and office to manage my ongoing foot issues that have been plaguing me for years! I cannot say enough good things about every single interaction I have with this office. Dr. Petersen is exceptional; he is knowledgeable, patient, gentle, empathetic and kind. I truly believe he has the patients best interest at heart, as recently evidenced by encouraging me to hold off on a procedure I was questioning doing that would be invasive as he felt it was too soon to consider it. So many other Doctors would just want to complete something and send you on your way to move on to the next patient, but he did not. He took a "wait and see" approach and was patient and understanding; he discussed the issue which I really appreciated. Every single interaction I have had with every single member of his team is always so on point! The office is well ran and everyone is kind, professional and helpful. I am dealing with a chronic issue I have had for years and both Dr. Petersen and all of his team members go out of their way to always provide a superior experience each and every time I am seen. The office always has an upbeat and fun vibe to it which helps when you are dealing with not so fun foot issues. Kudos to both Dr. Petersen and all of his team- I appreciate you! I encourage anyone seeking excellence in podiatric care to try this office.![]()

I met with Dr. Peterson on Friday for my very first time. He was more than Pleasant. He was actually very kind, funny and very welcoming and of course well educated on the structure of the feet, mine are an unusual pair? He was able to treat my foot immediately. I have a follow up in three months. I am very happy with how everything turned out. Glad to find a new podiatrist.
