In addition to our Berkeley-based team members, we also rely on our colleagues for some Onsight Workplace Wellness programs around the Bay Area. Karina Polanco-Jimenez and Sarah Hart are integral members of this group of seasoned chiropractors, health coaches, and massage therapists who share their warmth and expertise with employees at their workplace.

Karina Polanco-Jimenez

In-house personal trainer with PacWast Endurance

Sports saved Karina’s life after battling with a broken family that led her to find refuge in bulimia and anorexia as the quick solution to her problems, for her weight and body image were the only aspects of her life she had control of. This only led to a vicious cycle of falling into the pits of depression. Karina’s life changed drastically, for the better, during her last year of high school, after she moved from the High Desert to the city of Los Angeles where her new family allowed her to do sports. Karina’s desire and dream to play sports became a reality. Team sports gave Karina a sense of belonging she had never experienced before. Leading her school’s soccer team as their forward, in addition to her amazing performances jumping over hurdles and running almost every distance as a beginner for the school’s track team filled Karina with confidence that she could do great things and stripped her of fear from trying out new things in life. This newly acquired confidence and fearless spirit is what led her on a new adventure to Cal Berkeley for her undergraduate degree.

While studying at UC Berkeley, Karina continued to nourish her athletic passion and competitive spirit by training on her own and competing in local 5Ks. Always searching for new challenges, Karina self-coached and completed her first triathlon ever at the Oakland Triathlon Festival 2017, and placed 2nd in her age group (20-24). Karina fell in love with the sport, continued competing, and with only about a year of experience and the help of her team, PacWest Endurance, she has competed in National Championships and is on here way to represent Team USA 2019 at the Draft-Legal Sprint Triathlon World Championships in Switzerland.

Confidence, fearlessness, healthy body image, and self love are all qualities that Karina acquired as a result being active in sports and what motivated her to attain her Personal Trainer Certification to make a change in other people’s life as a Performance coach for PacWest Endurance. Karina believes that fitness and health is not a destination you can arrive at or something you can check off and think you are finished. Health and fitness goals one sets can be achieved through hard work and smart planning. Whether it is losing weight, gaining muscle, or improving sports performance, Karina desires to help others in ways that create natural and enjoyable habits that can be applied to everyday life. Karina believes health and fitness is a way of life. It is something we constantly have to work at and something we cannot live without.

Sarah Hart

LAc – In-house acupuncture

Sarah meets people where they are to empower them on their healing journey. Using acupuncture, Sarah helps patients reconnect to their own bodies and well-being.

Acupuncture supports resiliency in the body by stimulating it to heal itself. Using a scientific and holistic approach, it not only treats the symptoms, but the root causes of disease. Just as pain and disease can take us away from the activities we love, healing support can bring us back to life. Through treatment, she sees her patients’ lives come into balance with the relief of their symptoms, as well as improved sleep and, energy, better mental clarity, and a deeper sense calm.

After graduating Colby College pre-med with a degree in biology, she worked in the wildlife science, land use and watershed management fields, but was called back to medicine and patient care. When she learned that Chinese medicine treats by balancing the ecology of the human body, she knew she wanted to be an acupuncturist.

Sarah completed over 3,000 hours of didactic and clinical training to earn my MSOM, Master’s of Science in Acupuncture and Oriental Medicine at the Acupuncture and Integrative Medicine College in Berkeley, CA. She personalizes acupuncture treatments using diverse traditions including Dr. Tan’s Balance Method, Miriam Lee’s, Master Tung’s, and esoteric acupuncture. Her practice also integrates herbal medicine, medical qi gong, cupping, gua sha, and dietary therapy. She custom writes and prescribes herbal medicine formulas using both Chinese and western herbs.

She enjoys hiking, embodiment dance, yoga, qi gong, kayaking, mountain biking and long distance bike touring from Seattle to Maine. She can also be found lying in the sun on her boat home appreciating the water of the Bay.
