Steve R. Lasater MD trained in Family Medicine, which he has practiced since completing his residency in that specialty in 1982. He has subsequently specialized in the use of bio-identical hormone replacement therapy to treat the signs and symptoms of deficiency of the hormones estradiol (estrogen), progesterone, and testosterone that occur in women around the time of menopause, as well as the signs and symptoms of testosterone deficiency that occur in men as a consequence of aging. His approach is strongly evidence-based, relying not just on published guidelines but also on the scientific evidence underlying those guidelines. He has particular interest in the effects of hormones on cancer risk, and the interaction between hormone levels and cardiovascular disease risk.

Dr. Lasater also specializes in Clinical Lipidology – the science of lipid (cholesterol and triglyceride) management, and cardiovascular risk reduction. He has been awarded certification by the American Board of Clinical Lipidology. He also has achieved board certification in Hyperbaric Medicine and in Obesity Medicine.

Dr. Lasater has completed over 42 hours of Continuing Medical Education specifically addressing how to be an effective expert witness, including case reviews, depositions, and testimony at trial. He has been retained as an expert medical witness for over ten cases in recent years. He takes pride in his excellent communication skills and close attention to detail.
