Meet The Doctors

Dr. Jason Trainer, D.C. is a Chiropractor at El Cajon

Dr. Jason Trainer, D.C. graduated Cum Laude (with honors) with a Doctor of Chiropractic degree from Parker University in Dallas, Texas after completing two undergraduate degrees at Parker: a B.S. in Anatomy and a B.S. in Health and Wellness. While at Parker, Dr. Trainer was the recipient of the James W Parker Philosophy award, which recognizes a single doctor for demonstrating the principles of friendship, love of mankind, and compassion to serve in the practice of Chiropractic.

Dr. Trainer has continued his post-graduate education specializing in proper function of the spine and nervous system.  Dr. Trainer is so passionate about the benefits of a healthy nervous system that he joined a team of doctors on a mission to introduce chiropractic to the people of El Salvador with the ultimate goal of writing and passing laws recognizing chiropractic in that country.

Ultimately what motivates Dr. Trainer is a desire to help people live fuller, healthier lives due to losing his father to a massive heart attack at 57. Having lived through the pain of losing a loved one to a preventable disease, Dr. Trainer is on a mission to empower people to make wise choices regarding their health and wellness.

In addition to chiropractic Dr. Trainer also enjoys golfing as much as humanly possible and spending time in nature with his wife Jennifer and their 2 dachshunds, Snoopy and Red Baron.

Dr. Robert Ehrnman, D.C. is a Chiropractor at El Cajon

Dr. Robert Ehrnman has been a chiropractor since 1999 and became part of The Joint Chiropractic community in 2020. He began working as the local chiropractor in San Diego, California, where is he proud to serve his community.

Dr. Ehrnman gravitated toward chiropractic care after working in the physical therapy world. He began volunteering at a chiropractic office to gain exposure and he felt the calling.

He graduated with his doctorate from National Health Sciences University after studying pre-med.

Dr. Ehrnman says the best thing about being in the chiropractic field is the ability to help improve other lives without the use of drugs or surgery. He finds his work to be very rewarding and personally satisfying to see others find relief.

In his free time, Dr. Ehrnman enjoys spending time with his two young sons and working on house projects.

Dr. Justin Keffer, D.C. is a Chiropractor at El Cajon

Dr. Justin Keffer, D.C. joined The Joint Chiropractic’s network of doctors in 2020. He is currently working out of San Diego, CA and is very excited to serve his local community.

Dr. Keffer knew early on that he had an interest in healthcare as a profession. It was his chiropractor back in Ohio that set him on his path to Life Chiropractic College West, where he earned his Doctor of Chiropractic degree.

Through Dr. Keffer's professional journey, he has served all ages including infants through geriatrics for the management of a wide array of issues including headaches, neck pain, upper back pain, sciatica and of course maintenance or wellness care. He has been able to help others achieve their health goals through an optimal functioning nervous system and a well-adjusted spine, balancing the brain-body connection.

Dr. Keffer loves getting to know his patients, and making connections with his local community.
