Michael Millie, MD

Chief Medical Officer
Get to Know Mike

Mike has a proven track record of achieving financial success, strategic growth, and quality improvement while leading a large portion of our growing business. One of the most important strategies in these successes was pursuing increased engagement and investment in physician leaders at a time when physician leadership budgets were being gutted. The return on this investment was surprising, even to him, and confirmed the theory that providers still have meaningful control in ambulatory medicine.

Mike started by driving small projects within his surgery department and quickly moved to leadership roles in their professional liability insurance group. In 2011, he became chair of their large general surgery department. In 2013, he was promoted to surgery chief for the surgery section and ambulatory surgery centers. Together, with his physician leader colleagues, they have achieved operational excellence, including safety and quality, strategic growth and continuously improving financial performance. Through all of this work, Mike has followed the same principles: honor the patient and respect the provider. Slowly, we are aligning incentives, improving healthcare delivery and, ultimately, improving the nation’s health.

Why HarmonyCares?

“I want to transform healthcare. Nothing less. The goal is to align incentives for all stakeholders to increase value in the system. A daunting task, for certain. Through a mix of population health, business expertise and creativity the task is attainable as certainly as it is difficult.”

Brooks has extensive experience and passion for innovative public/private partnerships that drive innovative care models that align care and cost incentives across stakeholders. He was captivated by HarmonyCares’s mission and vision as a leading value-based care provider of in-home primary care services for people with complex healthcare needs.

Why HarmonyCares?

I believe in the transformative power of healthcare models that align incentives across all stakeholders and break down access-to care-barriers. HarmonyCares’ mission to deliver compassionate in-home care to vulnerable populations while advancing value-based care models was highly attractive to me. The company is perfectly positioned to provide unique value to patients and partners, and I look forward to being a part of the company’s success.

Chief Business Officer
Get to Know Alex

As chief business officer, Alex Sozdatelev leads the charge of business development, growth, strategy, and our Accountable Care Organizations.

Why HarmonyCares?

“I grew up in Russia where it is a norm, not an exception, that physicians and nurses are coming to homes to see patients who need care: from children to seniors. I know firsthand that it is a better model to treat patients, especially older and frail. I was genuinely surprised when I first learned that in the US sick patients need to come to a clinic or Emergency Room to get care. So, when I learned about home-based model like HarmonyCares’, I immediately recognized its benefits and got excited to grow such model and make it available to more patients across the country.”
