Dr. Altschuler is board certified in family practice and in addiction medicine. He completed his undergraduate degree at Dartmouth College, medical school at the UC Berkeley-UC San Francisco Joint Medical Program, and his internship and residency at the UC Davis Family Medicine Program. Most recently, he has worked at Cares Community Health, serving as the associate medical director, and providing primary care to patients who often have complicated medical, psychiatric, and substance abuse problems.

He has also been seeing patients who struggle with opiate dependency in his private practice. This experience-- direct relationships with patients and no insurance-- was a large part of what led to the creation of Sequoia MD.

He is the Medical Director for Diabetes Youth Families (DYF), an organization devoted to the quality of life for children, teens and families affected by diabetes. He has lived with type 1 diabetes for more than 20 years, and brings this knowledge and experience with him in his practice. When not working, he spends most of his time in the garden or with his family.
