I have lived in Las Vegas for seven years and have found the medical profession to be seriously lacking in professionalism and any type of common courtesy. When I finally was referred to Dr. Allen, for the first time in seven years I found a doctor that was not only intelligent but wise beyond his practice. He was able to diagnose some dietary issues that have been causing me grief and pain for 8+ years. He has put me on a regimen of vitamins and proper nutrition that has me feeling better than I have felt ever in my entire life. I cannot recommend him or his staff highly enough. His medical care and program is second to none in Las Vegas!
