Report
Aside from chiropractic treatments, Pinnacle Chiropractic also offers a number of other treatment options. These beneficial treatments were designed to improve overall functionality and well-being in a quick and effective manner.

*Adjustments Perhaps the most effective and popular form of chiropractic treatment, adjustments are designed to realign the body to its proper form, reduce or get rid of nasal conditions and allergies, repair damage from whiplash, help with depression, improve weight control and repair the body.

*Traction This type of treatment is complimentary to spinal decompression. It reduces back and neck aches, headaches and migraines. Patients also experience corrected spinal alignment and posture.

*Myofascial Release Technique and Trigger Point Massage Both of these muscle therapy treatments are a great addition to other chiropractic solutions. They help reduce pain and improve circulation and relaxation. These muscle therapies enhance muscle activity, blood flow and range of motion, while reducing muscle spasms, pain and muscle knots.

* Targeted exercises Adequate exercise is essential in order to assist in one's natural healing process. Our chiropractors assist in creating a personalized workout plan that involves exercises that are appropriate for you and your conditions. Target exercises enhance spinal protection, body function, muscle strength and posture.
Auto accidents can be very devastating events and leave your car and your body needing help. We offer auto injury rehabilitation services to ensure your injuries are treated early and don't worsen over time. At Pinnacle Chiropractic, our services can bring you peace of mind knowing that you will be okay and that your injury will be treated effectively.
Pinnacle Chiropractic and Spinal Rehab Center is part of a multidisciplinary provider network that allows us to use multiple parts of your In-Network insurance policy. At Pinnacle you are no longer limited to just your chiropractic benefit. Even though we are In Network with most insurance plans, there are some services provided at our clinic that are not covered by any insurance policy.
If you have been injured in a auto accident, you are not alone. Auto accidents are among the leading causes of injury among Americans, and often require medical treatment. Even if your injuries seem minor, we always recommend seeking medical treatment as soon as possible following an auto accident.
Many people believe that if the car is okay after an accident, they should be okay too. However, this isn't the case. Even accidents that have no effect on a car can end up having a significant impact on your body. After an auto accident, it is always best to get your body checked to make sure that any injuries are properly taken care of-even if you do not feel initial pain.
Over 30 million Americans suffer from spine related conditions every day. Neck and back pain affects everything you do, from work to play, and ultimately your quality-of-life. At Pinnacle Chiropractic, we have helped thousands of neck and back pain sufferers find lasting relief. We offer only the most advanced non-surgical treatments.

Doctor Casselman is amazing! I just compared my before and after treatment X-rays and I am so pleased to see the difference in the curve of my spine. I have significant pain improvement as well. His entire staff is friendly and courteous. I highly recommend this practice!

I had the pleasure of seeing Dr. Casselman and Pinnacle Chiropractic for the last few months while doing some physical therapy. This was one of the best experiences I have had. Dr. Casselman was so knowledgeable and really helped my get back to feeling better. The staff was always so friendly and welcoming. I would recommend anyone and everyone see Pinnacle Chiropractic. I will be coming back for routine adjustments.

Dr. Casselman and his stuff are absolutely wonderful, caring, and so kind! I was having pain in my back and neck which was causing horrible migraine. Dr. Casselman met with me and we discussed my treatment plan, he let me know up front what everything would cost. He is very knowledgeable I would recommend him to anyone and everyone.

Our chiropractor retired and I found Pinnacle online. I was impressed with all the reviews and awards. My daughter and I have been seeing Dr Casselman for about 2 months now and we love the whole office. I like the in depth information he has been able to give both of us.

I've been in a few car accidents over the last 4 years and had such bad back and neck pain it would bring me to tears. I tried to see other physical therapist and chiropractors but none seemed to really care for finding the actual problem. With Pinnacle chiropractor I'm actually getting results from my treatments, I can't believe how much better I feel from day to day.

This Doctor actually cares about his patients. The staff there is welcoming and encouraging which leads to such a relaxed and inviting atmosphere I actually look forward to seeing all of them every visit! They also have a small play area for kids as well so no matter the situation they've got you covered!

I have been a patient of Pinnacle off and on for a number of years. My profession requires sitting in a chair for hours on end for multiple days in a row. After a while the neck issues, back issues, arm issues start to creep back in. I make a call to Dr. C, and he knows immediately what the issue is and sets a treatment plan in motion. The staff is always friendly and professional. Dr. C gets me back to a good place to be able to continue working again. I am grateful for the office. They keep me going! Thanks ACDC and crew!

Walking into Pinnacle is like walking into the Cheers bar - it's where everybody knows your name, and you're always glad you came. Staff is exceptionally friendly - I'm regularly greeted (by name) in the office by staff I've never actually interacted with. Dr Cassleman does a fantastic job with treatment plans and monitoring progress, making adjustments to his adjustment plan, and managing expectations.

Of course, the success of your treatment plan is based on a team effort. and the patient is a part of that team (which Pinnacle wholly embraces). Coming in with feedback, detailed notes, and a general awareness of how your body is responding to each session makes a world of difference

Very friendly and definitely know what they are doing. I feel even better now than I did before my car accident! I want to thank all of you who worked there at the time I was your patient.

Dr. C and his staff are the Best! I was very skeptical about going, but Dr. C has done wonders with my neck and back! Very helpful in diagnosing an issue with my neck and head that my primary care physician had overlooked. They are also very family friendly. My three kids spend the time playing with their legos! Great staff! Great Doc!

I started going to Pinnacle a year ago. My life has changed so dramatically in that amount of time. Dr. Casselman is super knowledgeable about general health as well as chiropractic care. My chronic neck pain and headaches have significantly improved. He has given me so much advice on diet and healthy habits as well. Thank you Dr. Casselman!
Rob Young
When I went to Dr. Casselman I had been in a lot of pain for some years. He took some time to understand what was wrong with me. He sent me in the right direction to get help for my back. He is a honest man and really cares about people. Easy to work with and helpful. I will send friend and family to him if they need care.
Braeden Miguel
Was shopping around to different chiropractics in the area and the introductory deal was what initially caught my eye. After going though I would recommend them just because of the quality of service, care, and information they have. During both visits I have had so far they were willing to answer any questions I had, explain to me different treatment ideas for my pain, and work with my schedule and circumstances for the next visit. Would suggest them!

After having read many reviews of Pinnacle Chiropractic I decided that I would give them a shot. I first arrived with severe neck pain and in desperate need of some relief. Dr. C provided just that! I have been to many doctor offices in the past but none as professional and caring as the staff at Pinnacle Chiropractic. After my consultation I was given a personalized treatment plan and the neck pain I was experiencing had quickly disappeared within the first few visits.

Also I never knew going to a doctors office could be so fun! I would highly recommend Dr. C and his professional staff to anyone who is suffering from pain. Seeking treatment with Dr. C was the best medical decision I have ever made.

I moved to CO in 2014 and needed a new chiropractor. My husband saw Dr. Casselman's practice listed and recommended I contact him. Since I come from a background of traditional chiropractic, I didn't think I needed X-rays, but three years later I had issues that needed a look via X-rays. Dr. Casselman and I have had a few good laughs over this, but I can admit he was right and I am thankful that he worked with me in spite of my resistance.

I am happy to encourage potential new patients his direction, as he and his staff are all very professional and caring. They all are a great bunch of people who work to bring you into better health.

Dr. Casselman and his staff truly took the time to see my treatment through to the end. On the other side of his treatment/rehab programs, I walked out of his office feeling like I had my life back. It's invaluable to have people like them standing behind you when you're facing an injury you never thought you'd have at age 25. I highly recommend giving them a shot, you won't be disappointed.
Dustin Cantwell
My lower back was in bad condition with scoliosis causing sciatica prior to having treatment here. I was scheduled an effective plan that had a wide range of methods and treatments. The methods and treatments included, decompression of spine, having the chiropractor make spinal adjustments, use electronic device to stimulate the process of healing, exercise, massage, etc. Very effective treatment and feeling much better
Andrew
Dr. Casselman did a great job of explaining the diagnosis and setting up a treatment plan for relieving my neck pain and hand numbness. The treatments were successful in relieving these symptoms. He reviewed the results including improvements in range of motion and set up a long- term AT HOME maintenance program. I would highly recommend Dr. Casseman for anyone with chronic neck or back pain.

He takes a very professional approach and explains the pateints situation very well. I was a bit skeptical coming here but my fears quickly subsided when I walked in the door.

I was involved in a Motor Vehicle Accident and had suffered severe pain for the past year. After seeing multiple doctors and physical therapists, a co-worker referred me to Dr. Casselman's office. In the short time that I have been in treatment, I have seen such a significant difference. He has relieved so much of my pain and I am healing so much faster than I thought possible! Great doctor, great staff, and great facility!
