"Dr. Zack helped me at the most painful time of my life. I received a massage from another place of business and could not move or get off the ground for 3 hours! After being moved to a vehicle, we found that Dr. Zack was open and able to see me. Dr. Zack was able to gently manipulate my spine and get me on the road to recovery. (Don't get me wrong, it was not a fun experience...and it was painful, but I was in tears from the relief). Dr. Zack took the time to complete a full assessment even as a last-minute appointment and at the end of the day. Thank you so much Dr. Zack!!!!!"

"If you’re looking for help with mental, physical, or spiritual health – look no further! I can’t even begin to express how grateful I am to have met Dr. Zack Allen. About 1 year ago I was in tough shape. Prior to finding Dr. Allen, I experienced back-to-back spinal and neck injuries, lost 3 of the closest people in my life including one of my parents, and was just in an overall ungrounded/non-present state of being. Today, I feel as though I’m the luckiest person on the planet. Dr. Allen was instrumental in helping me through my physical, mental, and emotional shortfalls. An extremely conscious, caring, and genuine physician, Dr. Allen uncovers not only the feelings of your physical pain but taps into your body as it shows him signs of where those physical disorders are linked to – for me, they were most times linked to mental or emotional stress. Wherever it is hiding, Dr. Allen will find it. His alternative style of healing digs deep into an individual’s personal life history to really find the source(s) of imbalance in the body. Through herbal supplement remedies, calculated adjustments, or just some really great talks – Dr. Allen’s healing practices are all-encompassing. He is honest, patient, genuine, authentic, and kind. If you’re fighting a disorder or disease that normal doctors ‘just can’t seem to find a cure for’, you owe it to yourself to explore other alternative style healing arts. Given that my back, neck, and rest of my body are in the best condition of my life, I feel emotionally better than I have in my whole life, and feel more sustainably in the right health direction than ever – I can faithfully recommend Dr. Allen to anyone. Walk into your appointment with an open mind, and you’ll be sure to walk out feeling like a new person. Words cannot describe the magic that Dr. Allen works in his healing practices. I highly encourage you to go see and feel for yourself."

“When I first came to see Dr. Zack, I was having severe lower back pain that extended down into both legs reaching all the way to my knees. I could barely walk, it was very hard getting into and out of an automobile and my pain level was about 8.5 - 9 on a scale of 1 - 10. Dr. Zack began over a number of weeks treating me with ozone injections in combination with various spinal adjustments. He also provides me with several naturopathic supplements to improve my overall health. My visits to Dr. Zack have made a world of difference. Today I am pain-free, have lost 50 pounds and play on an adult fast pitch baseball team."

"When I came dragging into Dr. Zack Allen’s office for the first time, I didn’t know if he could help me or not. I barely had the energy to show up. Others had given up on me. I had several health problems and some were taking all my energy and enthusiasm for life.

First he said that I had adrenal fatigue. No wonder I was so tired! He has corrected that condition.  I brought all my supplements in and he helped figure out which ones were helping me, which were a waste of money, and suggested others. He has corrected problems that I didn’t even know were correctable.

Dr. Allen has also identified some problems that I did not know that I had.  He decided in what order my illnesses should be worked on for the best results.

I haven’t felt this good in years! I have the energy and excitement about life to enjoy it again! Dr. Allen is my new doctor!"

"After experiencing intense, sharp pain in my shoulder for weeks, I was concerned I had an issue with my rotator cuff. As an avid outrigger canoe paddler, I was in the middle of paddling season and couldn’t afford to miss many practices, or worse yet, quit the sport all together. Dr. Zack quickly ruled out any rotator cuff issues and suggested Prolotherapy. I received two shots to my shoulder and after three days, I was pain free. I returned to paddling practice at 100%, within four days. It’s been close to one year since my treatment, and the pain has never returned. Dr. Zack was very knowledgeable, attentive and answered all of my questions. I swear by his treatment and therapy, and highly recommend him to anyone experiencing simple discomfort to sharp intense pain. Thank you Dr. Zack!"

"I have been one of Dr. Allen’s patients since 2010. On December 31, 2013, Dr Allen did a treatment on me he calls Integrative Therapy. I have never had this done but I am open to anything that will help improve my health. As the treatment began, I closed my eyes as Dr. Allen had instructed me and to get comfortable. I have not been able to lay down flat for several years, so I had my left leg raised so that I was comfortable. As he started the therapy I become more relaxed and the tremors that I was having also started to diminish. I started seeing colorful light flashing out of my eyes. It started from the outer rim of my eyes and flashed out through my pupil. It was beautiful and relaxing. Ever since I was child, I have had this recurring dream that has always frightened me and I always made myself wake up. I am in a wheat field and the light is so bright and I am very little and I am holding someone’s hand. All of a sudden the hand is gone and I am afraid and alone in this bright wheat field. That vision came back to me while Dr Allen was doing the treatment. I was calm and not afraid and felt peaceful. I have had this dream every night since my father passed away 59 years ago and this is the first time I was at peace with this dream. Dr. Allen said that is was my soul and my father’s soul at peace with each other. I think I was mad at him for leaving me and now I have forgiven him. Also during the treatment while my eyes were closed, I could see Dr. Allen’s hands and exactly where he was at. When he had me open my eyes, I noticed that I was lying flat and not in pain. After the treatment, I felt better than I have in a long time. I am able to climb the stairs at my apartment without pain or having to stop to catch my breath. I also have had severe muscle spasms and after the treatment, they are gone and I have not had one since. My asthma has also improved. I walk taller and feel that I have more energy even after my dialysis treatment which usually put me down for the rest of the day. I want to thank Dr. Allen form the bottom of my heart for doing the Integrative Therapy on me. I can not believe the benefits of just one treatment. I am looking forward to more. Thank you Dr. Allen."

From the very first visit with Zack, I felt comfortable and confident in his ability, attention to detail, education and intuitive wisdom.  I have seen and worked with many chiropractor's and wellness facilitators over the years surfing the world on the WSL World Tour and in my own wellness practice.  Having the insight and experience with my own injuries and recoveries gives me the sensitivity to know and feel the difference in short term and long term healing work.  Zack has helped me heal old chronic pain, emotional blocks, and injuries from current and past in the short time that I have been working with him.  Not only is he highly skilled, but he is a kind hearted man with the best intentions.  He takes the time to listen and be present.
