About

Dr. Michael Cohen earned his bachelor’s degree in psychology from Dartmouth College in Hanover, New Hampshire. Dr. Cohen then received his medical degree from the University of Cincinnati College of Medicine in Cincinnati, Ohio. He completed his residency at both Boston City Hospital and Boston’s Veteran Administration in internal medicine and his postdoctoral fellowship in pulmonary disease at Boston City Hospital. In 1974, Dr. Cohen relocated to Contra Costa County where he continued his practice in respiratory care and pulmonology. Dr. Cohen was the Medical Director of the Pulmonary Services and Respiratory Therapy Department at John Muir Medical Center in Walnut Creek from 1974 – 2004. Dr. Cohen has been a member and has served on committees for the following organizations: California Thoracic Society, California Sleep Society, National Association of Medical Directors of Respiratory Care, California Medical Association, American Medical Association and the Alameda-Contra Costa Medical Association. Dr. Cohen founded the Respiratory Medical Group in 1974. The group joined BASS in early 2015. Dr. Cohen is currently the Medical Director of the Contra Costa Sleep Center in Walnut Creek.

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!
