DR. Chris Cucullu received his doctor ochiropractic degree from Palmer College of Chiropractic in Davenport, IA and graduated Magna Cum Laude.  He was born and raised in Anchorage, Alaska where he got to experience the outdoors and being involved in many sports growing up. Playing competitive hockey his whole life took a toll on his body, even at a young age, and led him to seek conventional palliative care from his family doctor, but led to no avail.  It wasn’t until he got under consistent chiropractic care that he experienced true correction of the problem and was able to break through to a new level of health. Chris went on to play collegiate hockey at Iowa State University where he received his Bachelor’s Degree in Kinesiology and Health and a Minor in Business, knowing the whole time he was going to pursue chiropractic as his purpose for serving people.  Dr. Chris loves watching hockey (his favorite team is the Pittsburgh Penguins!), going fishing, camping, golfing, reading and spending quality time with his friends and loved ones.

Dr. Chris has dedicated himself to over 200 hours in Neuro-Structural chiropractic outside of the regular school curriculum and continues to strive to do more to better himself for his patients!

His grandfather passed in his early 70’s from a heart attack after eating dinner with his family at a restaurant .
