Meet The Doctors

Dr. Nick Sorenson, D.C. is a Chiropractor at San Marcos - Grand Plaza

A native Northern Californian, Dr. Nick Sorenson is a sports enthusiast and routinely goes to the gym along with enjoying the outdoors whenever he gets a chance. As a 2014 Palmer West graduate, Dr. Nick Sorenson began his career in his hometown of Rocklin California where he was part time chiropractor. Growing up in a household of a Mother who works as a school teacher and Father who was an Elementary Principal for 20+ years, he had education in his blood. Therefore, prior to attending Palmer he graduated from Sacramento State with a Bachelor in Kinesiology where he earned his Physical Education teaching credential. After moving to San Diego in late 2015 he began teaching 3rd and 4th graders in the Del Mar Union School District. He loves being able to educate kids on Mondays followed by educating patients about the human body for the rest of the week here at The Joint. 

Dr. James Casteel, D.C. is a Chiropractor at San Marcos - Grand Plaza

Dr. James Casteel joined The Joint Chiropractic team in September of 2016 when he became the local chiropractor for both the Carmel Mountain and San Marcos clinics in San Diego, California. Dr. Casteel has been providing chiropractic care since 2012, after receiving his doctorate from Palmer College of Chiropractic in Port Orange, Florida.

He was born and raised in Huntsville, AL and moved to his current home of Carlsbad, CA in July 2013. Dr. Casteel first became interested in chiropractic as a profession when he injured his back playing basketball in college.

“I tried the traditional medicine route, and broke out in hives from the medication I was prescribed. Reluctantly, I tried chiropractic; and to my surprise after my first visit I felt about 60% better! After a few more weeks I was as good as new! So when the time came, I chose to apply to chiropractic school instead of medical school.”

Dr. Casteel loves having the ability to help treat and relieve his local community as his chiropractor did for him. He says the best thing about being a doctor of chiropractic is being able to provide immediate relief without the use of drugs or invasive surgery.

Over the course of his professional career Dr. Casteel has learned to serve a range of patients from infants to grandparents all with a variety of ailments such as sciatica, neck pain, upper and lower back pain, migraines, arthritis and much more.

In his spare time, Dr. Casteel can be found participating in outdoor activities such as surfing and snowboarding, or spending time with his fiancée, Rachna.

Dr. Casteel says he has done a lot of ‘cool’ things in his lifetime, but one of the coolest occurred while he was finishing up chiropractic school.

“I was chosen to go on a chiropractic mission/volunteer trip to India. We set up a free clinic for a week in Hyderabad and got to experience the amazing culture and people on the other side of the world.”
