When you're producing a magazine of 5280's size and complexity, every issue has to be a team effort. But this month two of our editors made extraordinary contributions. The October issue, which is now available on newsstands and online here, features our 16th annual Top Doctors survey. Even after all these years, Top Docs continues to be a reader favorite, typically selling far more copies on the newsstand in a single month than other local mags (ahem) sell all year long. And for more years than either of us would care to admit, Managing Editor Lindsey B. Koehler has cheerfully taken on the task of surveying more than 8,500 busy doctors and keeping this monster project fresh year after year. But she didn't stop there. Lindsey also teamed up with Research Editor Natasha Gardner to produce "Low on O2," our comprehesive guide to living at altitude. If you've ever wondered just how much we're all affected by our extraordinarily thin air, this is the package for you. Natasha was also busy this month. She weighs in with "The Two Lives of Helen Thorpe," an insightful and timely profile of an accomplished journalist (and newly published author) who also just happens to be Denver's First Lady. There's a lot more, of course. Check it out, and as always, don't hesitate to let us know what you think.
