Our Practice


Our practice has deep roots in Long Beach as it was first established in this location over 110 years ago. Dr. Clayton De Jong took over in the late 80's and his son Dr. Tyler De Jong is excited to continue the legacy. Ours has always been a private practice that focuses on quality patient care.  As specialists in Internal Medicine, we are well-equipped to meet your needs and take care of you in the community and in the hospital.  As primary care providers, we know it isn't just about treating a patient's disease, but rather building a relationship of trust to provide you the best care possible.
