About Us


Quantum Light Healthcare was founded in 2009 by Dr. Kat Halloran, ND and her wife, Amber.

They created QLHC in response to a troubling trend they saw medicine and medical care. Patients feeling unheard, unseen, misunderstood and unsupported.

Mainstream Medicine in the United States is designed to treat symptoms, body parts, lab values... but typically, not much consideration is put in to actually treating patients, treating people. 

We are committed to always using an integrative, functional medicine approach that supports the overall quality of life of the patient above all else. 

We want you to feel good and enjoy your life, and we would love to help you heal what stands in the way of that. 

Quantum Light Healthcare is intended to stand as a beacon of light and hope in the world by helping to improve one life at a time.

We Believe...


...that dis-ease is often caused by a variety of factors, not just the physical, and that healing must include support for all the aspects that led to the problem in the first place. compassion and that supporting a patient's heart, mind and soul can often be as therapeutic as medication. the healing power of the mind and the mind-set of the patient.

...that some sources of inspiration, empowerment, joy and healing cannot be measured scientifically (at this time...), and that should not make them any less important to the healing journey.

If you are looking for a healthcare model that seeks to address every aspect of life: physical, mental, emotional, sociological, and spiritual - you have found it...

Our Laser Story

In 2019, QLHC added their first Cold Laser to the practice.


A friend and colleague introduced Dr Kat and Amber to their EVRL Laser when Amber was struggling with a dangerous dental infection that antibiotics and all other options had been unable to address.  

After one 3 minute treatment applying the laser to the affected area, the infection cleared up.

This 6-week long health struggle and seemingly miraculous turn around created by just a beam of light... Well, it is an understatement to say that we needed to know more.

After several months of intense research, reading every medical study we could get our hands on, we decided that we had to go into Laser medicine because we needed to make this technology available to our patients. 

In many ways, we consider it the ultimate in "Alternative" medicine. The incredible health benefits, along with the complete lack of any negative side effects... in many ways, this is what we've all been waiting for in medical science. 

We are proud to offer 3 different specialized lasers in our offices right now -- with more sure to come soon.
