Brooke Clark
Finance and Marketing Coordinator

I have always loved to help people. From an early age, I knew I wanted to work in a field that would make an impact on the lives of others. I started out in customer service, but when the opportunity came up to help improve outcomes for preterm infants at Astarte Medical, I was ready for the challenge.

I had just earned my degree in Business Administration and wasn’t sure what I was going to do next—but this opportunity felt like the perfect place for me to make a difference. My son, Alexander passed away from complications when he was born prematurely at 25 weeks. This motivated me to find meaningful work that would honor his life.

Astarte Medical is a great place for me because we are all about making a difference and improving outcomes for our most vulnerable population. Every day brings new challenges and opportunities for growth, making me feel like what we do really matters.

Holly Clarke
Chief Operating Officer

Before joining Astarte Medical, I spent the bulk of my career in the consulting space helping Fortune 500s and scaling startups alike reimagine and redesign their processes and systems. As a client relationship lead that managed both external expectations and internal teams, blending empathy, relationship building and transparency with strategic planning, deadlines and deliverables became my strongest, most well-honed skill set. And it was always transferable, no matter the vertical—from financial services and automotive to healthcare and life sciences and any space in between. While I thrived on the variety each day brought, I began to seek something more; a deeper purpose for my work and the opportunity to work alongside exceptional leaders.

And then I met Tracy and Tammi. 

Their passion, mission and authenticity checked all the boxes on my “What do I want to do next?” list. These were the leaders solving challenges near and dear to my heart; the leaders that I wanted to work with. 

I am grateful to work with such smart, driven and kind people and I embrace the opportunity to position and enable our team to build truly life-changing technologies for our most vulnerable population.

Jeremy Dombroski
Chief Financial Officer

I have been in the accounting industry for approximately 25 years. Before working with Astarte Medical, I worked with Fortune 100 companies to small businesses in a variety of industries. I have had the most enjoyment working with small businesses that have passionate owners about their mission. I am able to bring my experiences to businesses like Astarte Medical and provide support as the team continue to focus on
their vision of growth. I focus on providing financial transparency to the executive team and investors while also refining processes to ensure scalability. I focus on serving the internal customers of the business so Tracy and team can provide high quality service to our external partners.

Prior to working with Astarte Medical, I started my career in public accounting and then moved on to hold roles as controller of two private equity backed companies, Director of FPA of a publicly traded business and CFO of a portfolio of small business. I am currently a Principal at the Eliassen Group in their Operational Accounting practice.

David Genetti
Chief Technology Officer

I love working with smart people to solve complex challenges. I have worked in a variety of roles but have always enjoyed making a difference. 16 years ago, my sister-in-law gave birth to twins at 27 weeks of gestation. They weighed under 2 pounds each and could fit in the palm of your hand. They are now amazing teenagers. The first 1,000 days are a critical period of development and Astarte Medical is providing tools to ensure that our most fragile babies can thrive.

I have a Molecular Biology degree but have focused my career on delivering technology that drives better decisions. After graduating from Princeton and working in big consulting for a few years, I was drawn to the impact that small companies can deliver. A tight knit team pulling in the same direction is a powerful force. Applying my experiences in financial services, software development and healthcare to help preemies achieve appropriate growth goals so that they can turn into amazing teenagers and people is a true privilege.

Before joining Astarte Medical, I was the CEO and founder of Affirmative Prescription Solutions. APS focused on providing prescribers real-time information related to opioid prescriptions. I have worked with the top financial services firms and have launched technology companies. Working with neonatologists, nurses and dietitians to standardize feeding while understanding individual needs is a challenge that I look forward to solving with our team.

William Hay, MD
Chief Medical Officer

Dr. William W. Hay, Jr. served as Professor of Pediatrics (Neonatology) at the University of Colorado Denver (retired). He was Head of the Section of Neonatology from 1982-1992 and Director of the ACGME/RRC accredited Training Program in Neonatal-Perinatal Medicine from 1982 until 2003. He also served as Director of the Child Maternal Health Program, now the Early Life Exposures Program and was Director for 36 years of the Neonatal-Perinatal Clinical Translational Research Center, for the NIH-NCATS-Colorado Clinical and Translational Sciences Institute. Dr. Hay’s principal administrative role was Scientific Director of the UCDenver–Department of Pediatrics/Section of Neonatology Perinatal Research Center. He is principal investigator and program director for an NIH-NICHD T32 Training Grant in Perinatal Biology and Medicine. Dr. Hay is widely published, with his research and scholarship appearing in more than 400 articles and books.

Dr. Hay graduated from Dartmouth College with a BA degree (cum laude) in biology and was a Senior Fellow conducting independent study in philosophy for his senior year. He graduated from Yale University School of Medicine in 1971. From 1971-1974, he completed an internship and residency in pediatrics at the University of Colorado School of Medicine and then served as Chief of Pediatrics at the U.S. Air Force Regional Hospital, Minot, North Dakota. He returned to the University of Colorado School of Medicine in 1976 for a research fellowship in Perinatal Biology and Medicine and as an Instructor in Neonatology. He became a full time member of the faculty of the University of Colorado School of Medicine in 1978 as an Assistant Professor. He rose to Associate Professor in 1983, to Professor in 1988, and received tenure in 1989.

Dr. Hay has conducted and directed basic, translational, and clinical research in perinatal medicine and biology for more than 40 years. His research, supported by NIH and occasionally other funding sources (e.g., the Bill & Melinda Gates Foundation) has been focused on the mechanisms by which maternal nutrition and diseases (such as diabetes) that produce different plasma nutrient substrate and hormone concentrations regulate placental uptake, metabolism, and transfer to the fetus of essential nutrients (principally glucose and amino acids), and in turn, how these processes are interrelated to nutrition, metabolism of nutrient substrates, hormone balance, and growth rate in the fetus. A major focus over the years has been on placental and fetal intrauterine growth restriction and both acute and chronic fetal hypoglycemia and hypoxemia and how these conditions in the placenta and fetus adversely affect fetal insulin production, variable insulin action, hepatic glucose production, skeletal muscle metabolism and growth, and other aspects of fetal metabolism and growth. This research is fundamental for learning how we might provide selective nutrition to the pregnant mother and nutrients, hormones, growth factors, and oxygenation to the fetus in order to better nourish the fetus and prevent or correct acute and long-term adverse consequences of abnormal fetal nutrition, growth, and development. Dr. Hay’s original studies of fetal glucose and oxygen metabolism focused on placental glucose transport and fetal glucose utilization. He has done pioneering work in developing methods using tracers (glucose and lactate) to measure rates of fetal glucose utilization and oxidation. More recent studies have focused on fetal insulin production and action (with Paul Rozance MD) and how both hypoglycemia and hypoxia induce fetal hepatic insulin resistance (with Stephanie Wesolowski PhD), in contrast to peripheral insulin sensitivity, that promotes glucose production that serves to sustain fetal energy metabolism in the presence of reduced glucose supply. Other studies are focused on how amino acid supply regulates fetal myocyte development and growth of skeletal muscle (with Laura Brown MD).

Aamir Nayeem
Senior Principal Engineer

I’m never really certain how I got interested in programming, but the roots were probably there somewhere at the intersection of building LEGOs and playing video games growing up. Building things, experimenting and tinkering with other things, and solving puzzles were how I spent a lot of my childhood. What better way to do all three at once than programming?

After graduating from the University of Pittsburgh with a BS in Computer Science and a BA in Sociology, I started my career as a developer working in fintech, primarily in a DevOps role. In addition to getting to learn some of the finer points of automation and release management, I also got to quickly learn how to engage in conversations with people with completely different frames of reference: how do you explain and quantify the value of continuous integration to the head of professional services? How do you review the impact of a bug fix with a certified financial risk manager?

As much as I enjoy programming, designing, and problem solving, there are always days where it’s just a little tougher to keep going. Whether it’s having to track down a difficult bug, reflecting on a meeting that didn’t go as well as planned, or any other challenges life throws us, it’s hard to keep your heart fully into what you do every day. On those days, I’ve found that there’s got to be something about what I’m doing that keeps me motivated. In fintech, I struggled to remind myself of that “underlying motivation” about what I was doing that told me to keep going.

These days, finding that motivation never seems to be an issue. I’m surrounded by a brilliant team that helps me think, learn, and grow every day. There’s always something fresh to look forward to at a startup. Above all, though, the impact of what I’m doing couldn’t be more clear. Having the opportunity to work to improve outcomes for infants is something for which I’m always grateful, and it pushes me to do the best I can every day.

Ryan Orman
Senior Principal Engineer

Over the years, I have developed and shipped software using countless technologies in a variety of industries ranging from ERP to medical devices. But finding that one company that can impact the healthcare industry in such a positive light has always eluded me. But I finally found it at Astarte Medical. The team’s ambition and challenge with the goal of positive societal impact has drawn me in as we work every day to improve healthcare tools that the less fortunate among us depend on; and in some cases rely on.

My careers trajectory has historically been driven on challenges. Working in the ERP industry has provided the challenges of fine crafting single solutions that improve business processes in a variety of customer’s organizations. My experience in medical devices has given me the challenge of developing complex software that interfaces with embedded technologies using wireless technologies such as MICS and Bluetooth. But I would drop them in a second to continue to focus on technologies that improve care for preterm infants. As the real challenge is solving the problems that help the most in need.

With an extensive software engineering and computer science background, I continue to be humbled by the ambitious, bright, and skilled team at Astarte Medical as we continue to work to solve the direst of problems.

Debbie Vorp
Chief of Staff

Growing up, I knew exactly what I wanted to do with my life. It was all planned out from college to retirement. I was going to fly for the Navy, then pilot the space shuttle and when I was too old for that, I was going to be a commercial airline pilot. Well… you know what they say about planning, be flexible!

Flexibility came sooner than anticipated. My eyesight was terrible and I was told no way could I ever fly. It was devastating!

Now of course, I realize that someone had bigger and better plans for me. In 2005, I started working at a venture capital company and the rest as they say is history. I met some wonderful people during those years but there were two that struck a nerve – in the best way possible. Throughout the years, Tracy, Tammi and I formed a close bond and a unique ability to work in unison. Needless to say, when the opportunity came to make a concrete difference in the world, how could I say no. Now I contribute to an incredible team fighting for those who can’t fight for themselves.

Was this my plan in life, no! But is it the best thing I could have ever hoped to do – yes!

Tracy Warren
Co-founder & CEO

I feel incredibly fortunate, every single day.  I’ve been blessed with good health, a beautiful family, great friends and a career I absolutely love. I wake not knowing what the day will hold.  My calendar is a good plan, but as the country song aptly says, “You make a plan and you hear God laughing”. The spontaneity and dynamism of life is what makes it so fun…so frustrating…and so fascinating. What matters day in and day out are the people. The people I work with, the people I meet, the people who challenge me, who support me, who make me the best I can be.

My career has taken me on a journey from the transactional to the transformational. A good start in banking provided fundamentals in deal structure and business assessment, but I realized my favorite part of every deal was the management team.  But when the deal was done we parted ways. I wanted more – to see how the story developed. So after business school, I transitioned to a venture investor supporting management teams, determining strategy, and forcing accountability in execution. My portfolio had ups and downs, there were winners and losers. I met good investors after whom I wanted to model myself, and others who taught me a noble profession can quickly be corrupted by greed and self-interest. And then it happened; I started my first company.

And then another. Then my first exit as a founder and entrepreneur. Building something, driving an organization, hand-picking the team with whom you work – that’s the ultimate career. I am honored to work side by side with passionate, bright, hard-working, ethical people who wish to make a difference in the world. I can’t wait to see where the journey leads, but I can tell you this, I’m just getting started.
