Edward Lin, MD, MPH, is an emergency medicine physician based in Walnut Creek, California. His professional career has focused on emergency medicine, a specialty dedicated to evaluating and treating patients with acute illnesses, injuries, and other time-sensitive medical concerns. Public records identify him as a physician whose work combines clinical expertise with a broader understanding of healthcare through his MD and MPH credentials. His role involves helping patients receive prompt care during urgent medical situations while supporting informed clinical decision-making. Edward has established a strong connection to the East Bay healthcare community, particularly in Walnut Creek and the surrounding Contra Costa County area. Public physician directories indicate that he has more than two decades of experience in acute care settings. Throughout his career, he has worked in environments where physicians are expected to assess patients efficiently and determine appropriate courses of treatment. He practices in a specialty where patients often arrive with immediate concerns, changing symptoms, or limited information. In these situations, physicians must evaluate risk, identify priorities, and coordinate care based on the patient's condition. The work requires careful judgment, effective communication, and a commitment to helping patients understand their healthcare options. Lin is most consistently associated with the practice location at 1450 Treat Boulevard, Suite 160, in Walnut Creek. Public listings connect this address with John Muir Health Walnut Creek Urgent Care. Additional physician directories associate him with John Muir Physician Network, John Muir Medical Center, Walnut Creek Campus, and Kaiser Permanente Walnut Creek Medical Center. These healthcare settings serve a diverse East Bay population and support a broad range of urgent and hospital-connected services. Edward Lin's professional identity is closely tied to emergency medicine. Unlike specialties that often involve long-term patient relationships, emergency medicine focuses on immediate assessment and treatment. Patients may seek care for pain, injury, fever, weakness, dizziness, shortness of breath, or other symptoms that require timely medical attention. Determining what requires urgent intervention and what can be managed through follow-up care is a central responsibility within the specialty.

I’m passionate about redefining what modern healthcare can look like. After graduating with my Bachelor of Medicine and Bachelor of Surgery from the University of Auckland, I wanted to combine clinical medicine with innovation, which led me to create Selfcaremen, a fast-growing men’s health platform now operating across New Zealand and Australia. My goal has always been to make preventative healthcare more accessible, engaging, and relevant for men, blending strong clinical standards with a fresh, modern approach.Alongside building Selfcaremen, I continue to invest heavily in my own training and development. I work as an Occupational Medicine Physician and RACP/AFOEM Registrar with Sonic Healthcare in Melbourne, where I’m undertaking specialist training with The Royal Australasian College of Physicians in Occupational and Environmental Medicine (2025–2029). I’ve also completed a Postgraduate Diploma in Occupational and Environmental Medicine from the University of Otago and hold a Postgraduate Certificate in Women’s Health. This background allows me to bring a practical, well-rounded perspective to healthcare, sitting at the intersection of clinical work, workplace health, and entrepreneurship.

Dr. Shiv Goel, MD is a board-certified physician and the founder of Prime Vitality Care, a physician-led functional medicine and wellness clinic based in San Antonio, Texas, with telehealth services available to patients in all 50 states. Dr. Goel trained in internal medicine and functional and integrative medicine, and has spent his career building a practice model that treats the root causes of poor health rather than managing symptoms in isolation. His clinical philosophy is grounded in the understanding that hormones, metabolism, inflammation, gut health, and mental well-being are deeply interconnected systems — and that lasting health improvements require addressing all of them together. Prime Vitality Care specializes in physician-supervised GLP-1 medical weight loss programs using semaglutide and tirzepatide, bioidentical hormone replacement therapy (BHRT) for women, testosterone replacement therapy (TRT) for men, peptide therapy including Sermorelin, BPC-157, and PT-141, and comprehensive functional medicine consultations for patients with chronic fatigue, gut dysfunction, autoimmune concerns, and metabolic disease. Dr. Goel is a sought-after expert on the clinical application of GLP-1 therapies, the role of hormonal imbalance in weight resistance, and the future of physician-led telehealth medicine.

Through Prime Vitality Care's HIPAA-compliant telehealth platform, Dr. Goel brings the same standard of clinical depth and personalization to patients nationwide that San Antonio patients have relied on in person — with lab coordination through local Quest Diagnostics or CPL sites and all prescriptions compounded and shipped directly to patients.
