Dr. Katie Gross

Gentle Relief from Neck Pain and Tightness

I had a great experience with Dr. Nor! I was having pain at the base of my head that turned into a headache and I had anxiety about getting a neck adjustment, but I heard Dr. Nor uses a really gentle technique so I tried it. The pain and tightness started to go away soon after the adjustments and my headaches are less frequent too. Would recommend if you’re normally scared of getting neck adjustments!

No More Suffering After Atlas Alignment

I have had severe problems with my neck for many years, having been rear ended multiple times over the past thirty years.
I have seen many competent chiropractors but none of them ever explained the role your atlas plays in the health of your neck. 
I would recommend upper cervical care for anyone with chronic headaches. If only I had had this type of care at the beginning I wouldn't have wasted so much time suffering.

Improved Sleep Cycles and Insomnia

Dr. Nor looked at me as a whole person rather than just a list of symptoms. I have had migraines and insomnia for over 20 years and she helped me find so much relief and was able to regulate my sleeping cycle.

Relief from Headaches and Neck Pain

Dr. Nor is a very kind and caring doctor who truly wants to help her clients. She is by far one of the best upper cervical doctors I’ve been to. I would highly recommend her to anyone suffering headaches and neck pains. Thank you!

Headaches and Vertigo from Contact Sports - Gone!

Dr. Nor is amazing! I was having terrible headaches and vertigo after playing a lot of contact sports. Now I'm doing great and feel awesome! I would highly recommend Dr. Nor and Performance Chiropractic!

Alison B.

Gentle, Long-Lasting Back Pain Relief

Dr. Nor is amazing. I have been to several other chiropractors in the past, but have never felt as pain free for so long. Her technique and touch are gentle while providing pain relief. Do not hesitate to see Dr. Nor if you are looking for back pain relief.

Major Improvements in Headaches and Neck Pain

I was under Dr. Nor's care for a little short of 6 months, & she was one of the best chiropractors I've ever been to. Under her care, I saw major improvements in my headaches / neck pain that nobody else was able to provide & her bedside manner was excellent. 

Gino G.

Reduced TMJ Pain and Migraines

Dr. Nor is incredible! She helped me with my TMJ and now I can enjoy solid food without pain. The treatments have also reduced the migraines. Dr. Nor has a great personality and always listen to my concerns. I highly recommend her!

Ana S.

This Technique is So Different and Gentle!

I have been to several chiropractors over the years, and by far Dr. Nor has been the best. I leave her office pain free and am able to schedule appointments further apart each time. Her technique is so different and gentle, yet so healing. I would HIGHLY recommend Dr. Nor. Thank you Dr. Nor for all you have done to relieve my pain.

People Don’t Know What They’re Missing!

I came in June 2015, a patient of Dr. Jeffrey Fowler in Florida – so I already knew the benefits of this type of chiropractic care. People don’t know what they are missing by NOT coming into your practice!

Debbie W.

Goes Beyond To Help

My issues were addressed and that gave me a high level of confidence in Dr Gross. She goes beyond the obvious to help. For example: I came in complaining of a different type of headache. She took my blood pressure and recommended I go in to my Primary Care physician. The fact that I went in sooner than later no doubt was very important.

Kathy B.

Positive First Visit

Office Manager Debbie set the stage for a positive first visit by answering many of my questions by phone in a friendly and knowledgeable manner. The office is a calm, professional environment that reflects Dr. Katie’s warm, welcoming and professional demeanor. She gave clear explanations and answered my questions without any feeling of being rushed. I am encouraged that this specialized treatment will be able to address my issues.

Janet C.

Friendly And Professional

Dr. Gross is very competent, friendly and professional. I am so happy she is my chiropractor.

Jason M.

Very Happy

I have seen many chiropractors, and healers, over the years, and have learned to differentiate (what I would consider) the good from the bad, just by speaking, and asking questions, that I would consider pertinent. This, all prior to letting them treat me, or my leaving with out treatment. Dr. Gross took all the time that was needed to go over everything with me. I liked that she listened to my problems, and her answers were with merit. Now, after a few treatments, I am very happy that I am under Dr. Gross’s care, and am hopeful that positive results will continue.

Wally S.


I’ve been seeing chiropractors for years and am excited to see there may be a real solution to my headaches and back pain. After only a few visits, I have experienced quite dramatic results with the Atlas Orthogonal practice – relief for intense headaches at the base of my skull, neck pain, arm numbness, scoliosis, and overall back pain and stiffness. I have felt misaligned for years and now feel an improvement in my yoga practice and a general feeling of getting back to myself. I would love to hear more details from Dr. Katie as she works on my spine and alignment during my appointments, I always love to learn more about what is happening. Thank you!

Alyssa S.

Severe Pain

Fantastic experience. Dr. Gross went above and beyond to help me out on short notice and in severe pain. She was highly accommodating and communicative throughout the entire adjustment and reached out several times after the fact to see that I was on the path towards recovery. Definitely a dying breed, this one.

Sloan A.

jaya Vertigo and Neck Pain

I want to thank Dr. Katie for giving me such great relief from my spondylitis problem. I had been suffering from severe upper neck pain due to spondylitis for the past two years and no amount of medication and pain killers gave me any relief. The pain killers only added to my misery by causing stomach related problems. Due to the spondylitis pain, I used to suffer from pain and numbness in my left arm, left shoulder and left side of the chest. Some times the pain got so bad that I had to rush to a cardiologist thinking I was having a heart attack. I also had severe vertigo and constantly felt dizzy.

Thanks to Dr. Katie I am totally cured now after 10 sessions at her clinic and I can now lead a normal life. I no longer have any pain or dizziness and I feel so healthy and good. I will strongly recommend treatment to anyone with problems similar to what I had.

warpeace Insomnia, Arm Pain and Numbness

My name is Warpeace, I began seeing Dr. Katie for pain that went into both of my arms. I also started having numbness in my fingers and it felt like my arms were asleep. After my first adjustment I immediately felt a difference. As my care went on I noticed that after 15 years of sleeping only 3-4 hours a night I was now sleeping 8 hours and more without waking! For the first time ever I had to use an alarm clock to wake myself up in the morning. Thanks to Dr. Katie and the Atlas Orthogonal technique I got my life back.

mohammed Headaches, Migraines and Brain Tumor

My name is Mohammed, I had been seeing Dr. Katie for headaches in the back of my head. They got better and I stopped having them, suddenly one day I started getting headaches in the front of my head. I came to see Dr. Katie and she sent me out for an MRI of my brain. I went to see her later that day for the results, she gave me the worst news of my life, I had a brain tumor. She sent me to the hospital immediately where I stayed for 2 weeks and underwent brain surgery. Today I am cancer free, walking, talking and blessed to be spending time with my family. I would like to say that I am grateful to Dr. Katie’s alertness when I described my symptoms that made her refer me to a brain MRI. her quick reactions when she knew of the results and guidance to me in the following hours helped save my life.

  • "I was very impressed with the chiropractic care I received from Dr. Gross. I had received chiropractic in the past for my neck pain, but not to this level of care. After only a few sessions, my symptoms began to disappear, especially my neck pain, and I know I would not have been able to perform to my everyday work functions without the treatment I received."
    Neck Pain
  • "As a court reporter, using my hands to type on a daily basis is a requirement. The work is speedy and can often last for hours at a time. Several months ago, every movement I made became excruciatingly painful. I started seeing Dr. Gross and got started on a program that helped right away. The doctor stressed the importance of my posture and proper hand and arm placement."
    Carpal Tunnel
  • "I have benefited tremendously from the chiropractic care I received from Dr. Gross. Not only has the adjustments helped alleviate my stiffness and aches, but it has helped me have more energy and just feel more balanced over all. A few months ago, I was able to resume a favorite hobby of mine - golf. Due to my previous pain, I never thought that’d be possible."
    Back Pain
  • "Dr. Gross has allowed me to be headache free for quite some time now. I used to have daily nagging headaches that often would turn into a migraine leaving me unable to function. For the longest time, I thought I could just keep taking medication to have the pain subside."
  • "It's been 7 months since I got wiped out by a monster wave. I sought treatment at the hospital and they took x-rays and said everything seemed normal, that I would just have some pain for a few days. A few days actually turned into several weeks, so at the suggestion of my girlfriend, I went to see Dr. Gross and was feeling better in no time!"
