Erik Isaacman, L.Ac.

Erik graduated from Kenyon College with a B.A. in Cultural Anthropology and a concentration in East Asian Studies. He moved to Portland to study acupuncture at the Oregon College of Oriental Medicine, graduating in 2004 with a Masters in acupuncture and Chinese herbal medicine.

Erik began his studies of Chinese language and culture in 1988. His first experience with acupuncture came after being hampered by post-surgical knee pain while training for a month long bike ride through western China. The acupuncture was so effective that he became intrigued by the practice of Chinese medicine and decided to explore a facet of Chinese culture which, until this point, remained foreign to him.

In 2004, after graduating, Erik spent five months studying Chinese Herbs in the Internal Medicine Department and the Gynecology Department of the TCM hospital in Wenzhou, China.  From 2007-2009, as an adjunct professor at the Oregon College of Oriental Medicine, he returned to China leading a five week post-graduate clinical internship.  

In 2015 Erik gained his certification in Sports Medicine Acupuncture (SMAC). This doctorate level training incorporates orthopedic evaluation and advanced acupuncture techniques, which allows Erik to better diagnose and treat injuries. 

Erik focuses on helping competitive athletes and weekend warriors recovery from musculoskeletal injuries, as well as addressing most chronic pain conditions. He also enjoys addressing women's health, treating digestive disorders and promoting surgery recovery.  Beyond acupuncture, he incorporates tuina massage, home exercises, Chinese herbs and diet therapy.

Oliver Leonetti, L.Ac.

Oliver graduated from Lewis and Clark College in Portland with a B.S. in Biology. In 2004 Oliver graduated from the Oregon College of Oriental Medicine, also in Portland, with a Master's degree in Acupuncture and Chinese Herbal Medicine. 

Oliver was introduced to acupuncture through a sports injury.  In 1996, after suffering from an injury to his foot, which required surgery, he stumbled into an acupuncturist who introduced him to Chinese medicine.  The treatment he received quickly reduced the pain and swelling in his foot and helped him fully recover from the surgery. 

His interest in anatomy, physiology and sports medicine has led to a deeper understanding of body mechanics.  In 2015 Oliver gained his certification in Sports Medicine Acupuncture (SMAC). This doctorate level training incorporates orthopedic evaluation and advanced acupuncture techniques, which allows him to better diagnose and treat injuries. 

Oliver begins with a thorough evaluation using orthopedics, muscle testing and postural assessment.  He uses a gentle acupuncture technique and combines acupuncture with tuina massage to achieve the best results for chronic and acute pain.  He uses his knowledge of yoga, stretching and exercise to help design treatments and home therapies to empower patients to take charge of their health. 

Oliver specializes in musculoskeletal pain, including sports injuries, chronic pain and surgery recovery.  He is a fluent Spanish speaker and enjoys working with a wide range of patients.


Casey McGuire, L.Ac.

Casey graduated from the University of Wisconsin-Madison with a B.A. in Psychology. After college he moved to San Francisco where he became a social worker for a homeless youth agency providing services to HIV+ street kids. During his employment he witnessed the profound effect that acupuncture had on his clients.  Acupuncture allowed them to experience fewer side-effects from their medications, assisted with drug withdrawal symptoms and eased emotional stressors. He immediately became intrigued.

Casey moved to Portland in 2002 and enrolled in the three-year Master's program in Chinese Medicine at the Oregon College of Oriental Medicine. A special interest in pain-related disorders prompted him to take extra classes and devote more clinic time to studying advanced acupuncture and massage techniques.  These skills are the foundation of Casey's practice today.

Casey's focus on musculoskeletal pain disorders, headaches and migraines is complemented by his ability to effectively treat poor digestion, auto-immune diseases and menstrual disorders.

Casey enjoys spending his free time hiking, biking, listening to music, traveling the world and spending time with his wife and son Knox.


Tanya Zhu, L.Ac.

Tanya graduated from the University of Minnesota with a major in Psychology and minor in Spanish.  It was during a study abroad trip that she discovered a love of Chinese medicine and acupuncture and decided to pursue it as a career.  She landed in Portland a few years later to attend the Oregon College of Oriental Medicine, where she deepened her knowledge of acupuncture, herbs and Asian massage.  In 2008, she graduated with a Master's degree in Acupuncture and Oriental Medicine and decided to stay in Portland permanently. 

Tanya's approach to health and wellness stems from her upbringing in a traditional Chinese family.  She remembers eating foods that were "cooling" and drinking herbal teas that "nourished blood".  She also watched as her grandmother went about a daily regimen of acupressure on various acupuncture points on the body.  To Tanya, health is about the intersection of mind, body and spirit.  She strives to provide the best traditional Chinese medicine to patients, incorporating acupuncture, herbs, Asian massage and qigong as a means to balance both the physical and emotional aspects of health.

Tanya's specialties include women's health, emotional issues, digestive disorders and musculoskeletal pain.  She's received additional training in various types of Asian massage and enjoys incorporating bodywork into her acupuncture treatments.  When not working, Tanya is known to make a jaunt or two out of Portland to the great outdoors and hike amongst the beautiful northwest scenery with her husband and her dog.

Sun Yun, L.Ac.

Sun is a graduate and teaching assistant at the Oregon College of Oriental Medicine (OCOM). He began his journey into the medical field by pursuing and obtaining a doctorate in pharmacy.  He practiced for 10 years as a pharmacist before shifting gears to pursue traditional Chinese medicine (TCM).  Burdened with multiple knee surgeries for sports-related injuries, he set out to explore less invasive options to the western medical paradigm of pharmaceutical and surgical interventions for pain relief and recovery.  With TCM, he discovered a path leading to a more natural, holistic, and balanced state of well-being and healing. He decided to forego practicing pharmacy to pursue his life’s calling. After graduating from OCOM, Sun spent two months volunteering in Nepal with the Acupuncture Relief Project, providing primary care and medical support to those with limited access to immediate and reliable healthcare. He has now joined our team of passionate and dedicated healers to address a wide array of ailments and conditions.  


Combining both his western and eastern medical knowledge, Sun incorporates the “best of both worlds” in his approach to healing and recovery.  He addresses all conditions and disease states and has a keen interest in physical assessment, orthopedics, and sports/work-related injuries, and musculoskeletal disorders.  He utilizes acupuncture, herbal medicine and a wide array of auxiliary healing modalities – Tuina massage, cupping, Gua Sha, moxibustion, and electro-stimulation – to effectively address the root cause of the condition.  

In his free time, Sun enjoys sports, exercise, martial arts, reading, and traveling to faraway destinations.
