Pamela Twu, MD


Read Bio

For Pamela, family medicine is not just about remedying illnesses or fixing injuries. It’s about being compassionate and concerned about a person’s wellbeing, and understanding the circumstances in their life. She enjoys working in healthcare because it is a privilege to care for others in need and to have a meaningful impact on one’s health and life.
Originally from Ohio, Pamela earned her undergraduate degree from the University of Toledo, and her MD from the University of Toledo College of Medicine and Life Sciences. She holds a California Physician and Surgeon’s License, and is certified in DEA and BLS.
Pamela is an avid animal lover and travel enthusiast. In her down time, she stays active by playing tennis, and indulges in her creative side by gardening, sketching and doing 3D origami, and playing the violin. 
My life experiences have allowed me to adapt to new situations, pursue my interests in science and medicine, and work well in a team setting. As a child, my family moved often, compelling me to acclimate to new places, people, and schools. Throughout school, I played the violin in various orchestras which required strings, winds, and percussion to work together to harmonize as an ensemble. As a bioengineering major, I was interested in identifying, treating, and preventing diseases. My senior design project resulted in a revolutionary device that combined geospatial sensing technology with a standard endotracheal tube. My curiosity led me to join a bioanalytical chemistry lab with a focus in ionic liquids as solvents for microextractions of pharmaceutical compounds, such as antidepressants and endocrine-disrupting phenols, from real-world water samples. This research is important as concentration of these drug compounds is found at minute levels in water that people are consuming. Consumption of these pharmaceutical drugs will have an effect on people’s health over the course of time. My involvement on the project led to a successful method of extraction for these potentially harmful substances. Another one of my projects involved developing a method to enhance the enantioselectivity of various chiral molecules, which is critical in the development of pharmaceutical compounds. Interested in more applicability to medicine, I also conducted research in an orthopedics lab where I synthesized chitosan microparticles for bone regeneration. My work has led to over ten publications, in which four of them, I was first author. I have also presented my research at several national conferences. These experiences have helped to sharpen my writing, communication, and teamwork abilities, all skills that I will bring to my clinical work. 
I practice healthcare because I always want to help people in any manner possible. Being able to aid the sick and injured, no matter if it is a minor irritant or major chronic problem, has been the driving force of why I practice medicine. I enjoy getting to know my patients both professionally and personally. Empowering patients through trust, mutual respect, and collaboration to reach their goals is exhilarating.

Michael Braccio, DC


Read Bio

While he has experience treating a variety of conditions, Michael has a particular interest in pain science, tendinopathies, and performance rehabilitation. His article on tendinopathy was featured in a publication for the American Chiropractic Association. He grew up playing sports which fueled his desire to help people move and perform better. Chiropractic is a field in which he feels he can help others who love movement to get out of pain and return to their activities and sports.

He went on to earn a Diplomate in Rehabilitation from the American Chiropractic Rehabilitation Board, becoming one of only eight chiropractors in Washington state with this certification. Michael also has advanced certifications in a variety of techniques and systems, including Selective Functional Movement Assessment (SFMA), Functional Movement Screen (FMS), RockTape Kinesiology Taping, and Graston Technique. His approach to treatment involves combining these techniques to reduce pain and improve function.

On the off chance that Michael is not in the clinic, he can be found at the ice rink playing hockey or in the mountains snowboarding. He used to skateboard as well, but his affinity to board sports stops at the shore—water activities are not his thing. An avid reader of all sorts of nonfiction books, some of his current favorites include Antifragile and Thinking, Fast and Slow. Born in Abilene, Texas, Michael grew up in Seattle.

What makes me unique?

I’m one of the few people that play ice hockey (and the majority of the ones that I know are Canadian).

Why do I practice healthcare?

I enjoy being able to help people get out of pain and achieve their goals. Meeting with people, getting to know them, and then partnering with them to overcome barriers is the best part of working in healthcare.

Jameece Pennix

Optometry Assistant

Jameece likes working in healthcare because there’s never a dull day. In the field, she enjoys all the ways there are to keep busy including helping a patient, communicating important information to other medical personnel, learning something new, or whatever else it may be that has your attention at that moment.

I’m almost always able to relate to other people in some manner, even if it’s just finding something simple that we have in common, which tends to make communication a lot easier and more comfortable than it may have been initially. I also really enjoy learning new things and am continuously finding ways to expand upon my prior knowledge.


I practice healthcare because I want to be able to make a positive impact in someone’s life––whether that is by relaying important information to them, helping them overcome anxiety and instead have a great experience at their appointment, or even something more life-changing. Additionally, I have a few relatives in my family that worked in healthcare, and my admiration for those strong women sparked an interest in me in the field as a child. And while I do not have a typical healthcare background, that interest stuck with me as an adult, and has motivated me to use what I have learned to help as many people as I am able to, in whatever way I can.

Halina likes working in healthcare because it gives her the chance to help people find the services they need, which she finds satisfying.  


Originally from Los Angeles, CA, Halina attended San Jose State University.


When she’s not at work, Halina likes to eat new things, so it makes sense that her favorite thing to do is try new restaurants.


A physical trait that ironically makes me “stand out” is that I am very petite and people often remember me by my height. A personality trait that makes me unique is that I am very vocal about expressing myself.
