Dr. Mark Foster, D.O.
Board Certified Family Physician
Dr. Mark Foster, DO is a board certified family physician and writer. He provides holistic and compassionate medical care for all ages, including pediatrics, with an emphasis on healthy lifestyle counseling and alternative mental health care. He has particular interest in helping patients withdraw from psychiatric medications that may be unwarranted and detrimental to their emotional and physical health.
Mark grew up in Littleton, Colorado and graduated from Chatfield High School in 1992. He attended Brigham Young University where he received a bachelor's degree in English in 1999. He then attended medical school at the Arizona College of Osteopathic Medicine, graduating in 2003 as a Doctor of Osteopathic Medicine (D.O.).

He has practiced full-spectrum rural family medicine in Worland, Wyoming, and traditional outpatient family medicine in Littleton, Colorado.
Through his experiences and self-education, Mark began to feel increasingly uncomfortable with the prevailing approach to medicine in the United States, which so heavily emphasizes prescription drugs. He found this most concerning in regards to psychiatric drugs, which are expensive and have been proven to have minimal effectiveness and serious side effects. He feels that there is a place for medications of all varieties, but that they should be used only when all other alternatives have been exhausted.
Additionally, Mark maintains a blog for his patients at www.markfosterdo.blogspot.com, and a blog in which he describes his approaches to mental health, www.madinamerica.com. He has written a novel and is currently working on a book about mental health reform.
Madhavi R. Patt, MD, MPH
Internal Medicine
Dr. Madhavi Patt is a Johns Hopkins trained, board certified internist, with over 10 years of clinical practice experience. Dr. Patt's membership based practice is focused on comprehensive primary and advanced preventive care for adults. The practice size is deliberately limited to a few hundred patients so that each patient receives the time, care, and attention to detail needed to achieve optimum health and well being. Traditional primary care providers are charged with caring for an average of 1500-2500 patients. It is extremely difficult to develop and maintain a strong doctor-patient relationship in this type of practice setting. Dr. Patt practices based on the principle that the most important factor in health care is the patient. She emphasizes mutual accountability to make sure the patient´s goals are met.
Dr. Patt adopted this model so that she could practice medicine the way it should be practiced-- unhurried, compassionately and comprehensively. Her focus is not only to provide state-of-the art care during illness but to prevent illness and improve quality of life .
Unlike "conceirge" practices which do not accept any insurance, Dr. Patt´s membership based practice accepts most insurance plans, including Medicare.
Dr. Patt attended Rensselaer Polytechnic Institute, with a scholarship for women in science, where she received a bachelor´s degree in Biology. She then attended medical school at Albany Medical College through a combined, accelerated program, graduating in 1996. Prior to her final year in medical school she obtained a Master´s in Public Health from Columbia University. Dr. Patt completed her Internship & Residency at Boston University, 1999, and then went onto a Fellowship in Internal Medicine at Johns Hopkins Hospital, Baltimore, MD, where she conducted research on chronic disease management improvement and cardiovascular disease prevention through lifestyle measures.
Dr. Patt has extensive practice experience in a wide variety of clinical settings including the Veteran´s hospital, Internal medicine at Harvard Vanguard Medical Associates, Boston, MA and Johns Hopkins Hospital, and Urgent care at Johns Hopkins Hospital, Denver Health, and Highlands Ranch. In addition to her clinical experience, Dr. Patt was an advisor for health policy in the United States Senate 2001-2002, a Consultant to HRSA (Health Resources Services Agency), 2002, and to start up health care companies, 2007-2008.
