Gail Boyer Hayes is a retired lawyer and a lifelong writer and editor. While a senior associate at the Environmental Law Institute she wrote “Solar Access Law: Protecting Access to Sunlight for Solar Energy Systems,” Ballinger 1979, a pioneering book that helped launch a new field of law.

She is now one of the longest surviving patients with this usually fatal disease, and has served on the board of the Pulmonary Hypertension Association (PHA). Gail authored the first three editions of “Pulmonary Hypertension: A Patient’s Survival Guide.” Sometimes called “the bible” for PH patients, this book has been translated into half a dozen languages and has sold well around the world, earning money for PHA. The current English edition is available from PHA.

She is an inactive member of the District of Columbia, Colorado, and California state bars and now resides in Seattle, Washington.
