San Francisco Bay Area Foot and Ankle Residency Program - Residents

Denny Chung

Dr. Denny Chung was born in Los Angeles, CA, raised in Phoenix, AZ. He earned his Bachelor’s degree in Biology at the University of Washington while working full time at Virginia Mason Medical Center as an Orthopedic Technician. Within his personal experience as an orthopedic technician, he realized that being part of the patient’s care can be extremely rewarding. Though he was participating in the patient’s care, he realized that the limitation of his title would never allow to dictate the care the patient sought. Through many mentors, he discovered the field of podiatry and eventually, pursue and obtain a Doctorate of Podiatric medicine, from Samuel Merritt University – California School of Podiatric Medicine, and was awarded membership into the Pi Delta Honors Society.

Though his interests in podiatry lie in orthopedics, reconstruction and trauma, Dr. Chung loves the multifaceted nature of podiatry where facets of dermatology, orthopedics, vascular and wound care are involved. Outside of medicine, he enjoys spending time with family, cooking, snowboarding, hiking local trails, and kart racing. Dr. Chung is very honored and excited to join Kaiser Permanente team to provide high-quality healthcare, improve the health of the community and most importantly, thrive.

Miriam Jones

The healthcare journey which led me to Kaiser Permanente was as unexpected as it was rewarding. As a Kentucky native, I attended Transylvania University for my undergraduate education. Following college, I was lucky enough to fall into a job as the Medical Assistant for a Podiatrist at Bluegrass Orthopaedics. For four years, I served our patients in a wide array of roles. This job was the spark that ignited my passion for patient care, medicine, surgery, and all things foot and ankle.

I went on to become a Doctor of Podiatric Medicine at Dr. William M. Scholl College of Podiatric Medicine in North Chicago, Illinois. There, I built my medical knowledge in the classroom before learning from attending and resident physicians across the country while out on rotations. I traveled from the east coast to the west coast, and everywhere in between, from hospital to hospital, furthering my education and skill level until I ultimately decided that Kaiser Permanente’s Podiatric Medicine and Surgery Residency was where I wanted to receive my surgical training. Lucky for me, it was a match! Now that I am here in the Bay Area, I’m eager to continue my education by working with KP’s talented physicians, residents, and staff as well as the diverse patients that come through its doors.

When I am not at the hospital or on the job, I enjoy spending time with my Husband and our two border collies while hiking, kayaking, fishing, or just lounging around. I also dabble in golf and would enjoy any tips you might have! I look forward to meeting you.

I subsequently obtained a Master of Biomedical Sciences before earning my Doctor of Podiatric Medicine degree with honors from the Western University of Health Sciences College of Podiatric Medicine.

Before starting podiatric medical school, I worked as a medical scribe for a busy Foot and Ankle Surgery private practice in Los Angeles, an experience that introduced me to the field of podiatric medicine and solidified my passion for lower-extremity care. During my medical education, I was inducted into the Pi Delta National Honor Society and received several academic distinctions, including the Commander Kim Voth Wound Care Endowed Scholarship and the Stephen M. Geller Graduate Merit Award.

I have long been committed to community service, particularly through volunteer work at free clinics and outreach programs serving underserved and Spanish-speaking diabetic populations. Providing culturally and linguistically concordant care is deeply meaningful to me and remains an important part of my practice.

Within this residency program, I appreciate the strong sense of teamwork and family-like support among the residents, the comprehensive exposure to high-volume trauma, and the unique landscapes of Northern California.

Outside of training, I enjoy exploring the Bay Area with my husband—discovering new hikes, riding the ferry, and sampling the city’s diverse food scene. I also value how easy it is to make quick weekend trips to Los Angeles to visit family and friends. It is a true privilege to be able to train at this program , to gain such invaluable experience and work in a comprehensive healthcare system like Kaiser Permanente.
