Lewis A. Osterman
A trusted voice among experienced Denver estate planning lawyers, Lewis works directly with individuals and multigenerational families from Highlands Ranch, Centennial, Thornton, and across the state. A University of Colorado–Boulder graduate, Lewis earned his J.D. with honors from Boston University School of Law and is an active member of WealthCounsel, a national leader in resources and support for estate planning attorneys creating high-quality, customized plans. Named a Colorado Super Lawyers Rising Star every year since joining the firm, he blends deep technical knowledge with a gift for listening—creating estate plans that fit each client’s life, assets, and values. Earlier advocacy for patients injured by unsafe medical devices showed him the high cost of courtroom battles and cemented his commitment to proactive planning. Clients appreciate his clear explanations, prompt follow-up, and genuine concern for their family’s future.

Since founding the Osterman Law Firm in 1982, David guided Colorado families through wills, trusts, elder-law issues, and estate taxation with rigor and empathy. A Brandeis University graduate and former Law Review editor at the University of Toledo College of Law, he built the practice on meticulous work and long-standing relationships—values that continue under Lewis’s leadership. David’s dedication earned the firm an AV Preeminent® rating from Martindale-Hubbell and helped establish the WealthCounsel network of premier estate-planning attorneys. Though retired, his legacy shapes every matter we handle.
