Frequency Specific Microcurrent (FSM) is a technique for treating pain using low-level (microamperage) electrical current.  The current is delivered to specific body parts in an attempt to relieve pain.  A frequency is the rate at which an electronic pulse is produced, measurable in hertz (Hz).  In using FSM in the clinical setting, it has been indicated that various frequencies can be used to potentially reduce inflammation (swelling), repair tissue, and reduce pain.  It is a non-invasive and painless treatment that may help reduce pain without drugs or surgery. Dr. Jessie was trained by Dr. Carolyn McMakin, a pioneer and leader in the field.  

FSM is currently being researched and utilized at the Cleveland Clinic, at the Walter Reed National Military Medical Center for Wounded Warriorsat Shirley Ryan AbilityLab in Chicago, and elsewhere.

Truly a Miracle in a Box!

--Tom T,
retired golf professional & telehealth client

"Hi Dr. Jessie, I ran FSM Protocol #4 again last night before bed.  I am quite pleased with the reduction of pain we've already achieved.  I could immediately feel the difference when I reached behind my back to tuck my shirt in.  I can't wait to get out on the golf course again. 


I’m not totally out of the woods, but it sure beats the heck out of the surgical alternative.  I am totally stoked to get started on my journey to better physical and mental health. I think this [Frequency Specific Microcurrent Home Unit] is truly a miracle in a box. Thanks a million!"

Mold Toxicity & Sinus Pain

--Trey S, 
Loving Mom & Telehealth Physical Therapy Client

"I am so impressed with my Home Unit.  I started FSM to treat inflammation and pain in my gut and to help me recover from a pretty severe toxic mold exposure, and FSM gave me relief the very first time I ran my unit! 


More recently I felt like I was coming down with a sinus infection, which is very rare for me. Everything I was doing to treat myself—colloidal silver, high dose vitamin C, anti-inflammation diet—was just not quite kicking it.  After just one sinus pain protocol, my headache, pressure, and discomfort are gone! I was bracing myself to have to go on antibiotics which I really didn’t want to do, but now it looks like I’m in the clear. Thank you so much for making this available!  FSM is truly amazing!"

Optimum Health

--Shawn G,
yoga instructor & saivite

"I highly recommend FSM through Jessie if you are feeling that optimum health is one of your goals. After having cramped, painful fingers from snow shoveling, and also suffering stiff ankles from years of standing on cement for my job, just a few FSM treatments helped decrease my pain and improve my range of motion significantly, and the results have lasted."

Healing in Your Hands

--Laura W.,
Data Scientist

“FSM is amazing. Dr. Jessie has worked thoughtfully with me, along with Tracy's evaluation of test results, to plan protocols for my highest priority concerns.  She is insightful, smart, and clearly dedicated to her practice and her patients. I feel dramatically better in many ways after renting a unit, and I am so grateful for the hard work The Healing Collective has done to make the FSM rental program possible.


FSM is supported by promising preliminary research studies; I'm hopeful that the future holds many more of these studies to evaluate FSM's multiple applications and to support putting healing back into the hands of patients.” 

Provider & Advocate

--H. Graham

“I’ve been very happy with my results using Frequency Specific Microcurrent.  Dr. Tierney always makes herself available, she is very easy to talk to, has a collaborative mindset, treats me like a human being and not just a patient and truly has a heart and passion for treating people to ensure they have the best outcome.  She invested a lot of time programming my unit … most of which has been accomplished during a pandemic.  I'm very thankful to have Dr. Tierney as a health care provider and advocate.”

Back Pain(less) & Quick

--Kathryn T,
veterinary technician

"I had extreme lower back pain and muscular pain in my shoulders.


I was treated by Jessie with FSM (frequency specific microcurrent). The treatment was painless and took less than an hour.


The next morning, I woke up after the best night of sleep I've had in awhile and had NO PAIN.  I feel AMAZING.  Definitely recommend and will be returning to Jessie for PT and treatments."

A Talented Healer

--Nathan M, biological research scientist

"Jessie is a talented healer who intuitively combines the ancient science of yoga with modern PT techniques in manual therapy and energy medicine.  Weaving these modalities, Jessie custom tailors empowering treatment plans that meet patients where they are, building on their strengths to help them regain wholeness after working through injury and illness.  

In a world where medicine is increasingly fast-paced, it is rare to find such a talented clinician who takes time to breathe with her patients, truly listen to your needs, holistically focus on mind, body & spirit, helping you connect with accessible tools for wellness. 

Jessie is a skilled manual therapist with an innate ability to quickly find tender spots and address the imbalances that created them. Unlike conventional physical therapy programs, Jessie's integration of yoga postures and therapeutic movements provides a functional, neuromuscular foundation that is directly relatable to the day-to-day movements that carry you through the world. Although it is difficult to bang out ten repetitions of a particular core exercise while standing in line at the grocery store, taking a moment to root down through your feet, align your spine and enjoy the serenity of a slow exhale is quite attainable and feels great! Dr. Jessie explains that by doing this not only are you retraining and strengthening your core but also relaxing your nervous system.  This and many other practices she has to offer can be taken anywhere, and through persistence, they become part of a lifestyle that leads to optimal health.

I highly recommend Dr. Tierney to anyone looking for a clinician and teacher to help guide you on a path toward reaching your highest potential."
