Chiropractor Mark de Dubovay D.C. 

Doctor of Chiropractic

Certified Traditional Naturopath

“Since childhood, I have been fascinated by and studied the intricacies, as well as the balance of nature and the human body. This fascination continues today. In my practice of alternative medicine I have found the opportunity to continue my studies and apply my knowledge to improve my patients’ health.”

Dr. Mark deDubovay was born and educated in Los Angeles. As director of the Advanced Wellness Center he enjoys providing the best of alternative medicine to the community. Wishing to enhance communication with his patients, he asks to be called Dr. Mark.

Dr. Mark is a former member of the faculty and currently serves as a supervising doctor for chiropractic interns. He is a past director of the Long Beach Area Chiropractic Society.

“Just a short note to let you know I am very grateful for all your help and words of encouragement. I am now in Oklahoma and doing well. I’m continuing my back exercises and am doing much better. It feels good to feel good again. Again, thanks very much.” - Denise E.

Dr. Mark was invited to practice at the prestigious STATIC Clinic in Bologna, Italy. The clinic specializes in pain treatment and disorders of the spine. Its staff includes the best chiropractors from America who work alongside an international group of medical orthopedists and physical therapists. He worked at the clinic for three years before joining a private practice in Paris, France where the focus was on combining chiropractic with progressive holistic medicine. Dr. Mark’s international experience greatly broadened his knowledge of other chiropractic techniques and holistic medicine. And to this day, he continues to speak Italian.

“I so appreciate your intuitive understanding of my body and energy system. Your use of a variety of modalities is very effective in returning me to a state of balance. I always leave an appointment feeling that my entire energy system has been attended to, rather than just the symptoms I came in with.” - Bonnie B.

With a firm commitment to education and research, Dr. Mark is able to offer his patients the latest in alternative medicine. This pursuit of education led to his certification by the American Naturopathic Certification Board as a Traditional Naturopath. His research also lead him to become an expert in the exciting field of cold laser therapy. Dr. Mark holds the distinction of being appointed by the FDA as a primary investigator in a research study on the benefits of cold laser therapy for osteoarthritis of the hand.

“Words can’t express how grateful I am for all the extra time, guidance and words of encouragement. Thank you for helping me in the process of better health. You’re a great doctor and your heart is in the right place.” - Dave V.

Pursuing a holistic approach to his patients, Dr. Mark offers preventative health measures, as well as treatments of chronic conditions. With children and the elderly in mind, he has developed safe and progressive techniques combining very gentle chiropractic and a broad range of natural healing solutions using naturopathic approaches.

She assisted patients through respiratory and stroke rehabilitation as well as instructing geriatric and post-surgical patients how to walk and regain independence. “I found tremendous fulfillment in assisting patients to improve their health and quality of life. It was my desire to help people on a different level that led me to chiropractic medicine.”

Dr. Shur is a record-holding long distance runner and her practice includes many athletes. She has trained in a range of techniques including Sacro-occipital (utilizing the gentle force of gravity to balance the spine through adjustment of the pelvis) and cranial adjusting (subtle manipulation of the skull bones to insure proper natural movement).

She also has attended my daughter, Amanda, for sports injuries and a serious automobile accident injury. A runner herself, Dr. Shur gave special attention to Amanda’s running complaints and, further, served as a valued role model and friend during Amanda’s developing teen years.” - Sandy M.

Dr. Sese Novas was born and raised in Spain and maintains her fluency in Spanish. She was introduced to holistic care by her father, who refrained from using pharmaceuticals and instead opted for home remedies and nutritional therapies.

Dr. Novas’ interest in natural ways of healing intensified as a result of her athletic activities. This led her to become a certified massage therapist. She developed an interest in chiropractic after experiencing its healing power following a car accident, which left her with intermittent back pain. She was soon enrolled at the Los Angeles College of Chiropractic. She first earned a Bachelor of Science degree and then completed her Doctor of Chiropractic in 1993. Dr. Novas is a member of the California Chiropractic Association.

Dr. Novas uses a full range of soft tissue techniques, capitalizing on her background as a massage practitioner.

Dr. Novas is a firm believer in the team approach to wellness and will refer patients to other practitioners in the Center if she thinks their condition would be improved by the consultation. “My main goal as a Chiropractor is to help patients achieve optimal health without the use of drugs or surgery, encouraging them to capitalize on their own ability and desire to improve their health.”

Dedication to physical exercise has inspired Dr. Novas to become an avid runner and a long-time practitioner of the martial arts. She has also incorporated yoga into her regular regiment and views it as a perfect complement to her exercise routines. She enjoys the amazing benefits this ancient art has to offer.

Married with two beautiful daughters, Dr. Novas is a very involved volunteer at their school and with their Girl Scout troop.

Drew Nystrom, LAc

Acupuncturistc-Drew-Nystrom Licensed Acupuncturist

Drew was introduced to massage at a young age, as he and his older brother used to massage his Dad’s sore back after long days of construction work. Finally at age 21, Drew enrolled in a year-long massage program.

With more than 1,000 hours of massage training completed, he graduated with honors from Maric College (now Kaplan), acquiring a Holistic Health Practitioners Degree. After working in the massage field for a few years, Drew realized that there was so much more to learn.

While researching possible schools to further his education he found, right here in Los Angeles, the highly respected Emperors College of Traditional Oriental Medicine. Being well versed in martial arts (Ninjutsu and Kung Fu) he was already familiar with Chinese Medicine.

“Continuing my education in this field helped me understand the balance between healing arts and martial arts and the balance one needs in life. I found my calling. Four incredible years later in 2011, I graduated Magna Cum Laude with a Masters in Acupuncture and Oriental Medicine.”

Drew’s time at Emperors allowed him to work with some outstanding doctors. He was also able to work within the Los Angeles community at the school’s onsite clinic and at the UCLA Arthur Ashe Student Health & Wellness Center.

“My goal as a health care practitioner focuses on bringing the individual back to a desired state of health. An analogy I like to use is how a plant needs a certain amount of sunlight and water. With the correct sunlight and water the plant will flourish and grow strong. However, if the same plant is a full sun/outdoor plant that’s locked inside with minimal light, it will not grow strong, even if you water it correctly and give it fertilizer. This is the same for people. Not everyone is the same and I enjoy solving the puzzle of how each patient differs and what is needed for that individual to flourish and achieve optimal health. In other words, find the ‘root’ of the problem.”

After graduating in December 2011, and passing the state boards, Drew moved back to his hometown of Temecula where he married his sweetheart. One year later, he and his bride moved back to Long Beach Area to make this beach town their home.

In his spare time Drew enjoys the outdoors – surfing, practicing and teaching Martial Arts (Tai Ji Chuan and Qi Gong), and spending time with family and friends.

Office Hours:

Friday 9:30-1:30
Saturday 9:00-12:00

Sharon is a California Licensed Acupuncturist and a National Diplomate of Acupuncture, and holds a Master of Science Degree in Oriental Medicine from Samra University.  She specializes in women’s health (fertility, pregnancy, gynecology, autoimmunity, overactive bladder), digestion and pain.   Her post-graduate training includes the treatment of chronic eye disease, male/female infertility, pediatrics, and Functional Medicine.  She is currently working on an Associates in Nutrition.  Her work as a Clinical Research Coordinator at the John Wayne Cancer Institute provided Sharon with an understanding of the western medical model of treating bone disease and cancer.

In her thirteen years in practice, Sharon uses an integrated approach, with Functional Medicine lab testing and assessments at the heart of her treatment strategy.   Functional Medicine looks at the root cause of illness, much like Chinese Medicine.  It’s just one of her tools in her tool box.  Her personal view is that environment and lifestyle play an integral role in wellness.  “We don’t have to “inherit” the genes of our parents”.  Through her studies in genetics and epigenetics, Sharon believes that we can reverse many so-called “inherited” diseases by using food as medicine, along with other healing modalities.

She is passionate about the results her patients obtain--delighted when a patient is on a path towards healing.   Sharon has a gentle yet intentional touch, using a Japanese-style of painless, superficial needling.


Rebecca Rebmann, CTN

CTN-Rebecca-Rebmann Certified Traditional Naturopath
When Rebecca Rebmann joined the Advanced Wellness Center she added her expertise to the nutritional therapies and weight loss services. She is a Traditional Naturopath with a Bachelor’s degree in Natural Health Science and a Master’s Degree in Holistic Nutrition

"My goal is to empower people with a clear understanding of healthy diet and lifestyle and how making even small changes toward better habits can dramatically improve the quality of their lives.”

Rebecca’s commitment to healthy living and nutrition has been a lifelong passion. After 12 years in the produce industry, she combined her interests for health and wellness, knowledge of fresh produce and retail skills to open several natural, gourmet food stores and restaurants in the Northwest.

“I can describe my experience working with Rebecca Rebmann at AWC in two words: life changing! My understanding of proper healthcare and diet has been broadened extensively. I am now equipped with better tools to navigate both my life and the lives of my entire family by making more informed decisions needed so that we can ‘eat to live.’ I exceeded my goals: weight loss, enhanced awareness of cause and effect of food choices and supplement free! Indeed, this has been a truly remarkable and life-changing experience.” - Patricia P.

Now at AWC, healthy weight management and wellness are Rebecca’s primary focus. She addresses digestion and food allergies – two of the often-overlooked obstacles that keep people from achieving lasting healthy weight. Additionally, she works with clients to correct hormonal (PMS and menopause) and neurotransmitter imbalances, fatigue, type 2 diabetes and immune deficiencies. Rebecca is able to guide clients to restored balance and wellness by using a combination of non-invasive, highly sensitive laboratory testing and non-drug therapies, such as: detoxification, proper diet and supplementation.

“What Rebecca has done for me is truly priceless. For a long time I lived overweight, uncomfortable and unhappy with myself. When she recommended a ten-week program, I thought I did not have it in me to follow such discipline, but she guided and encouraged me. Nine weeks later and 30 pounds lighter, I realize what I actually got is more years of vitality and healthy living, and that is truly priceless. Thank you Rebecca!!” - Eduardo C.

Scientific advances in wellness are being made everyday and Rebecca believes that ongoing education is a key component in the evolving field of nutrition and wellness. She continually furthers her education to learn about new breakthroughs and therapies. She is passionate about promoting food safety, sustainable agriculture and is active in the movement to prevent harmful food production technologies.

Rebecca is happy to announce that she has been awarded the NEI Certification and is currently using it in her practice.

Optimal health is only possible when the nervous, endocrine, and immune systems are in balance. Imbalances occur as a result of exposure to psychological or physical challenges. Underlying stressors such as mental stress, poor diet, unhealthy lifestyles, infections, environmental toxins, and general immune system regulations will alter the NEI Supersystem and lead to poor health. Addressing symptoms while identifying root cause disturbances will restore nervous system function balance and improve patient outcomes.
