Aspen Animal Hospital Clinical Leader Dr. Anne Cooley Navigates WellHaven Ownership Shift
Dr. Anne Cooley leads Aspen Animal Hospital through a shift to WellHaven ownership, balancing high-altitude medical complexities with the local housing crunch.

Aspen —The wind off the Roaring Fork cuts through the valley floor, rattling the windows of Aspen Animal Hospital. Inside, the air is thick with the smell of antiseptic and the low hum of ultrasound machines. It is a place where a dog’s heart condition doesn’t just depend on genetics, but on how thin the air gets at 7,800 feet.
Dr. Anne Cooley knows this better than anyone. She arrived in 2011, fresh off a divorce and a career restart in Minnesota. She didn’t just walk into the local business scene; she forced her way in. A job fell through in Carbondale. She walked into Aspen Animal Hospital and asked for a job. They hired her on the spot.
That was thirteen years ago. Today, she is the clinical leader under WellHaven ownership. But the business model is shifting, and the challenges are mounting.
Cooley doesn’t sugarcoat the reality of practicing veterinary medicine in Aspen. There are no referral centers nearby. General practitioners here don’t just check teeth and give shots. They perform ultrasounds. They do echocardiograms. They handle noninvasive and laser surgery. For the really tough cases, they bring in an anesthesiologist. They manage blood transfusions in-house.
Altitude changes the physiology. Animals arrive from sea level with underlying heart conditions. The thinner air triggers pulmonary hypertension. You can’t treat a sea-level patient with sea-level protocols. You have to keep training.
The Aspen Times reported that Cooley spends her time getting to know clients. She follows up on patients. She earns trust. It is more about relationships than anything else. People see you as the new person. They think the person before you was better. You have to prove it every day.
Now, the practice is selling to WellHaven. The ownership structure is changing. The algorithm of care is being rewritten. But the core problem remains: how do you keep skilled staff in a town where housing is a luxury and the air is thin?
Cooley says they always reach for the best care they can provide. They know their limits. They consult specialists. They learn together. But the cost of doing business is rising. The housing crunch is tightening. The altitude isn’t going anywhere.
Locals watching the shift in ownership need to ask what this means for the bottom line. Does WellHaven’s model solve the housing crisis? Or does it just add another layer of bureaucracy to a system already stretched thin by geography?
The animals don’t care who owns the building. They care that someone is there. Someone who knows how to listen to a heart in thin air. Someone who can find a bed for a nurse when the market is empty.
Cooley is still here. She’s still leading. But the rules of engagement are changing. And in Aspen, you don’t get to opt out.
