“I began treatment by Dr. Gustin at Pacific Coast Sports Medicine / Regenerative Orthopedics Clinic earlier this year (2016) after having encountered a pamphlet put out by the facility claiming to be able to not only prevent osteoporosis, but to create osteogenesis ( bone building) without the use of prescription medications and their noxious side effects. Having practiced as a nurse anesthetist (CRNA) for 44 years prior to retirement, and having, over those years, anesthetized thousands of geriatric patients for fractures (a large portion of which were femur and hip fractures), I knew the value of prevention. As we age, we lose muscle strength, balance and proprioception and our eyesight declines setting us up for falls more frequently than the younger population. The dire consequences of hospitalization to treat these falls include blood clots, pneumonia, urinary tract and operative site infections. These can be deadly in this vulnerable population. Dr. Gustin has tested and documented my level of osteopenia / osteoporosis and is treating me using the Biodensity and Power plate machines. She offers recommendations for home exercises, dietary changes and for bone supplementing vitamins and minerals. She uses chiropractic techniques to treat my spine scoliosis and neck pain. I am so grateful for noticeable improvement in that area. We are tracking the changes in my bone density. Many insurance companies and health care facilities urge their prescribers to seek preventive treatment by getting annual check ups to include: basic cardiac and blood pressure checks, Pap smears, chest X-rays, mammograms, colonoscopies, screening for skin cancer, etc. They have, unfortunately, omitted care of the skeletal system and have failed to offer preventive check ups for osteopenia / osteoporosis and for the spine pathology that occurs with aging. I urge the public at large to take matters into their own hands and to seek testing and treatment on their own. The old adage about an ounce of prevention being worth a pound of cure is so true when it comes to your bones, joints and related structures. Your insurance company, although they don’t advertise, may cover treatment.” – Ilene Richards, CRNA

“After a terrible fall, I immediately had my husband take me to Dr O’Brien! He has been taking great care of my arthritic hands for some time now. He immediately took care of me, xrays, mri, cortisone shots, for my newly sprained back. 8 weeks lying flat! …relief came from Dr O’Brien’s referral to Mary Jo Gustin! [Dr. Gustin] has to be the world’s best chiropractor! I’ve never been fond of that particular service, as I don’t like to get cracked. Mary Jo is gentle and warm and caring. I’ve been seeing her 2-3 times a week for adjustments, laser, and comfort. I will refer anyone who needs physical therapy, a good Ortho doctor, and a fabulous chiropractor. Now, Mary Jo is helping me strengthen my bones with some fabulous new equipment. No Osteoporosis for me!” – Linda Tisherman (from

"Dr Gilligan and staff are so friendly and welcoming; I felt very comfortable the moment I walked through the door. In addition, the care is amazing. I felt like a whole new person just after one visit (stimulation and adjustment). I was having moderate knee, low back and hip pain and it was practically gone the first time. I have gone back a few times since and continue to receive top notch care and customer service. P.S. I also received an amazing massage!"

"I recently gave birth to my first child and received excellent prenatal chiropractic care from Dr. Dave and his massage therapists at The Back Center. Most new moms would agree, it's no picnic having a demanding tenant in your gut for nine months. As my pregnancy progressed so did my aches and pains as well as my need for a relaxing mental break. I worked with Dr. Dave to address specific tension points and relieve my back and hip pain. I also received therapy treatments by every therapist that works there (depending on whom was available). Their attention to detail and tips for stretches and what to do between visits made the last few months much more bearable. The combo of therapeutic massage and chiropractic treatments are both a mental and physical necessity for any expecting mommy! Thanks!"

"I highly recommend Dr. David Gilligan if you are looking for a chiropractor! I was suffering severe migraines for over a year. When I met with him he assured me that the natural therapies they offer are the first line of defense for my headaches and that medication was the last resort option. I did exactly what I was told and sure enough my migraines have disappeared. Thank you Dr. for helping me and my family!"

"Dr. Gilligan and his staff have done an excellent job for me in relieving pain and discomfort in my neck and lower back. He is exceptionally professional and his methods work. I would highly recommend Dr. Gilligan for all chiropractic issues."

"I had been to a chiropractor before I came to the Back Center and Associates. It was not a good experience. Then one day, I met Dr. Dave Gilligan.We talked for a while. Later, Dr. Dave came back and invited me to come visit his office. He could tell by looking at me that I needed and would benefit by treatment.

He was so very positive, pleasant and caring that I decided to go see him. The office was full of happy, pleasant people. The staff is very professional and caring. Dr. Dave was extremely professional and positive. I was afraid to relax because of my previous experience.

Dr. Dave always takes the time to listen. It took hardly any time at all for me to relax. I trusted Dr. Dave and my trust has not been misplaced. My treatments with Dr. Dave are always relaxing and pleasant.

My conditions have greatly improved, my muscles are remembering where they are supposed to be and do. Dr. Dave also gave me exercises and other suggestions which have greatly improved my conditions. I have become more healthy overall, I did not have a serious cold last year, and I have gained weight to a healthy weight.

I attribute this to a more all around healthy condition do to my having chiropractic treatment.The people in this office are the best, most professional,most caring, just plain good and happy people who really care about you.

I thank God for the day I met Dr. Dave Gilligan. My life is truly better.

Back Pain

"I have a chiropractor right down the street from me, and I could go there, but I would rather travel 23 miles to go to Dr. David Gilligan’s office. Why? Great service from him and his staff. He always knows what my problem is and how to fix it. When I make an appointment, I am always seen right away. I don’t think I ever had to sit and read a magazine in his office! My most recent visit was for a sacro-iliac dysfunction. When I described the symptoms, Dr. Dave knew right away what it was and told me I would be feeling better in about 3 visits. Sure enough, he was right. I have also been to see him for injuries from a car accident, with neck and back pain. Between the electrical stimulation machine, the icepacks, the therapeutic ultra-sound and the adjustments, I always walked out of there feeling better than when I went in. Dr. Dave is gentle, compassionate, always cheerful, and most of all, he gets results. He also has a massage therapist in the office, who is very good, and I understand there is a new decompression table as well. So, it’s painful at the gas pump to travel to see Dr. Dave, but my pain goes away once I’m leaving his office."

"Dr. Gilligan and his staff keep me PAIN-FREE! I have always been active in sports and usually have something bothering me, whether it was my neck and arms one week or my back and hips the next. Since I have been getting adjusted regularly by Dr. Dave I can truly say I have no problems anymore. I feel better than I have in years and will continue to see him for what I believe to be the best adjustment in town. Thank you Dr. Dave!"

"My school-age kids are involved with a competitive soccer program and play soccer five days a week. To keep their physical condition the best it could be, they see Dr. Dave for adjustments and for the muscle therapy.

They are definitely more resistant to injuries and we have seen an improvement in their flexibility and strength.

I have been taking thyroid replacement medication for several years. For the past six months, I have been receiving weekly adjustments and muscle work from Dr. Dave and his staff.

Recently, I found out that my thyroid has seemed to jump start and my dosage has been reduced in half. Also, my back feels better and I feel great!"

Matt Miller

"My name is Matt Miller. I played football for Arizona State University for 5 years and am currently trying out for the NFL. When I came to Dr. Dave Gilligan I had tight hamstrings and sore knees. Since being treated by Dr. Dave, he has really helped my entire body loosen up.

Additionally, my core balance and agility has improved through the training and neuro-muscular re-education program Dr. Dave put me on. I have also gained weight and gotten stronger after the therapeutic massage treatments by Dr. Dave’s licensed massage therapists. They are the best I have been to.

The overall body treatments at the Back Center have really showed in my game. For me, it slowed everything down and has allowed me to run better routes and keep my body in optimum shape.

I would recommend Dr. Dave to anyone."

"I will start by saying what an amazing staff Dr. Dave has!! So professional, pleasant and accommodating!! I was in a car accident and was suffering from whiplash among other pains. My neck and shoulders were so tense; I had headaches, back aches, and just felt so tired! Dr. Dave let me know this would be a journey but reassured me that he would get me back to feeling normal and pain free; and that he did! I went in for adjustments once, sometimes twice, a week and for therapeutic massages for 4-5 months. I would tell him what was going on and he knew just what it was and how to fix it! I always left feeling better than when I walked in and each month my pain was diminishing! He also taught me the importance of my posture, daily intake of water and stretching. Extremely flexible with scheduling! Dr. Dave and his staff genuinely care about my well-being. I can’t thank him and his staff enough! I feel great and I sleep better at night which gives me more energy throughout my day! Not only is he an amazing Doctor but has the best personality and a contagious laugh!

I promise you will leave with a smile on your face and feeling better!"

"They were so easy to reach in an emergency, they answered my call immediately. It is a relief to know that I can count on them to always be there for me when I need them the most. I'm always amazed at how considerate and concerned they are for my well-being. Their advice is always wonderful and completely unbiased. All of my questions were answered during my appointment, and the doctor seemed very knowledgeable. They were happy to answer each and every question I had in-depth. It was very easy to get an appointment. They have a very flexible schedule and get me in quickly every time. Everyone in my community knows that they are the absolute best in the field."

"I felt much better after my appointment. My pain was greatly reduced. They paid close attention to me and all of my questions were answered. Their staff is the most friendly, welcoming staff I've ever dealt with. They are so warm and professional, and make the whole experience that much better. I was so impressed with the progress I was able to make after visiting them. All my questions were answered, and I feel a lot more confident and hopeful about the future."
