About

Dr. Gregg Pottorff is a board-certified orthopedic surgeon. He completed his undergraduate degree at the University of California, Santa Cruz, where he graduated with a Bachelor of Arts in physics and economics. He then attended Stanford University for medical school and an orthopedic residency. From there, Dr. Pottorff completed his fellowship in sports medicine at the Kerlan-Jobe Orthopaedic Clinic in Los Angeles. While he considers himself a general orthopedist and often treats fractures, sprains and strains, Dr. Pottorff has both subspecialty interest and extensive experience in arthroscopic surgery and joint replacement using minimally invasive surgery techniques. Dr. Pottorff’s interests are shoulder arthroscopy (rotator cuff repairs, labral tears, etc.), knee arthroscopy (ACL reconstruction, meniscal tears, etc.), hip arthroscopy (labral tears, femoral impingement, etc.), hip, knee and shoulder replacement (both full and partial) and cartilage restoration procedures for damaged joints. He is usually able to prevent the need for surgery and uses the latest injection therapies (including platelet rich plasma and hyaluronic acid) to help heal chronic degenerative joint and tendon conditions.

Dr. Audrey "Lisa" Arzamendi is double board-certified in internal medicine and endocrinology. Since 2012, she has specialized in diabetes, obesity and metabolism, thyroid disease (including Hashimoto's and Graves'), polycystic ovary syndrome (PCOS) and sex hormone disorders, adrenal and pituitary dysfunction, osteoporosis, parathyroid/calcium disorders, and thyroid and parathyroid nodules and cancers. She is highly trained in ultrasound-guided fine-needle aspiration (FNA) biopsy of the thyroid (99% diagnostic rate).

Dr. Arzamendi is committed to safe and established medical treatments, and prides herself on staying informed about emerging therapies and research-supported non-prescription options. She is experienced working with all forms of brand-name and generic thyroid medications, and as a type 1 diabetic herself, has first-hand knowledge of nearly all available prescription and technological diabetic treatments, to best support patients in selecting their optimal diabetes treatment regimens.

Dr. Arzamendi graduated with honors from Stanford University, with a BA in Human Biology and a concentration in Health & Human Performance.  She attended UC San Diego School of Medicine (receiving a federal NIH National Cancer Institute fellowship), and completed her internal medicine residency at Kaiser Pemanente’s Santa Clara Medical Center.  Her endocrinology training was completed at UC Davis Medical Center. She previously practiced in California's South Bay before relocating to open her practice in Walnut Creek in 2020. Dr. Arzamendi was a Stanford varsity athlete and still enjoys running, hiking, tennis, rowing, and other outdoor activities. She loves spending time with her husband and many pets, and looks forward to being your doctor!
