Jan Carlo Zegarra, DC

Chiropractic Physician

I am the chiropractic physician at the St. Joseph Hoag Health Wellness Corner. I love helping to restore people to good health and giving them the tools to stay well. I bring expertise in chiropractic medicine, physiotherapy, exercise rehabilitation and nutrition, and I have worked with patients of all ages and fitness levels. I have extensive experience with athletes, including professionals in the NFL, NHL, MLB and UFC.

I understand what it’s like to be in pain and have less-than-optimum health. As a former professional volleyball player, I was derailed by a back injury that took me out of my sport. After working with a chiropractor, I got well enough to get back in the game. That experience motivated me to pursue chiropractic medicine.

In my area of expertise, I focus on understanding the root cause of a problem and utilize a variety of manual therapy and exercise techniques to accelerate recovery and prevent injury from occurring again. I advise my patients to take active roles in their health and wellness. I have a Bachelor of Science degree in physiology from the University of California, Santa Barbara. I also earned a Bachelor of Science degree in biological sciences and my Doctor of Chiropractic (summa cum laude) at National University of Health Sciences in Lombard, Illinois.

In my spare time, I enjoy playing and coaching volleyball, and being outdoors with my wife and two sons.

I’m the physical therapist at the St. Joseph Hoag Health Wellness Corners. I love using my training and expertise to help people overcome their health challenges and feel better. As a board-certified exercise physiologist and a certified Pilates mat instructor, I bring a range of education and skills to my role.

I’ve worked in a variety of care settings, including St. Joseph Hoag Health’s Mission Hospital, where I helped people with neurological disorders and patients recovering from joint replacement, cardiac and other procedures.

I enjoy using my personal and leadership skills to enhance patient care and like being part of a dedicated team that works together to help our patients on their path to healing and wellness. I have a doctorate in physical therapy from Clarkson University and a bachelor of science in exercise science from University of New Mexico.

In my spare time, I enjoy teaching Pilates, spending time outdoors with my family, and actively exploring Southern California.

In my spare time, I enjoy hiking, meditation, cooking, reading and scuba diving.

Samantha Mueller

Physical Therapist Assistant

I am the physical therapist assistant at the LA Fitness Wellness Corner Irvine-Crossroads. You could say that you’re in good hands with me because I’m responsible for the Bodywork massage program. This service is more than just massage for relaxation. It’s an important therapy that many health providers recommend as part of post-surgical and even neonatal programs. Other people use Bodywork to relieve medical conditions such as stress, chronic pain, inflammation, and muscle and joint injuries. Additionally, Bodywork can help with mental health and detoxification.

I also provide the physical therapy follow up appointments and carry out the plan of care of the physical therapist. The physical therapist and I work as a close team to provide exceptional care to all our patients.

I believe that there are many ways to assist my patients on their paths toward natural healing. I am trained in a variety of Bodywork techniques, including myofascial release, soft tissue mobilization, trigger point release, effleurage and reflexology. I work closely with my fellow health care providers and clients to select the right course for their care.

Before coming to the Wellness Corner, I helped provide physical therapy to people with Parkinson’s disease, stroke, cerebral palsy, pulmonary concerns and pelvic floor problems. I have experience with strength and endurance training, balance and gait training and other physical therapy techniques. I have witnessed firsthand the effectiveness of a wide range of physical and natural healing techniques.

I earned a Bachelor of Science degree in kinesiology from California State University, Fullerton followed by earning my physical therapist assistant degree from Stanbridge University, graduating summa cum laude. I am a member of the American Physical Therapy Association (APTA). In my spare time, I enjoy doing community service, spending time with my family and being outdoors.
