How One Clinician’s Vision—and Sound Credit Union’s Support—Brought Belmar Cardiopulmonary Diagnostics to Life

How One Clinician’s Vision—and Sound Credit Union’s Support—Brought Belmar Cardiopulmonary Diagnostics to Life

Every business has a backstory. For David Earley, owner of Belmar Cardiopulmonary Diagnostics (Belmar), that story began with something many healthcare workers know too well: fatigue.
“It was the overwhelming sense of dread that came over me when I woke to prepare for work,” says the founder of Belmar. “I was commuting to care for people often at their worst, while working in a system that didn’t always see patients as people. That was the catalyst. I knew something had to change.”
Driven by a desire to restore dignity and humanity to healthcare—and inspired by a long-term vision of building generational wealth for their family—then Earley took a leap of faith and started putting pencil to paper. From that vision, Belmar Cardiopulmonary Diagnostics was born.
What Belmar Cardiopulmonary Diagnostics Offers: Clinical Precision with Compassion
What truly sets Belmar Cardiopulmonary Diagnostics apart is their unaffiliated status, allowing them to accept referrals from any provider. They also offer cash payment options, ensuring access even when insurance falls short. Most importantly, Belmar offers same-day consultations with highly trained specialists—making the path from diagnosis to treatment seamless and patient-centered.
“Our focus at Belmar also includes bringing our testing models into preventative medicine,” Mr. Earley shared. “We aim to empower our community members to recognize the value of proactive care. By using testing methods traditionally employed for diagnosing and managing existing conditions, we can help individuals establish and sustain effective exercise and dietary habits. This approach has the potential to significantly reduce the future risk of developing chronic heart and lung diseases.”
Located in Bellevue, WA, they offer an impressive range of advanced cardiopulmonary testing services, including:
- Cardiopulmonary Exercise Stress Testing
- Vo2 Max Testing
- Anaerobic Threshold Assessment
- Resting Metabolic Testing
- H.A.S.T. (High Altitude Simulation Testing)
- Pulmonary Function Testing (PFTs)
- Exercise & Methacholine Challenge Testing
- Arterial Blood Gas Sampling
- FeNO Testing for asthma
- EKG and Dexascan
- Exercise Prescription & Wellness Programs
Overcoming Early Challenges
Building Belmar meant building something that didn’t exist before.
“There wasn’t a model for Belmar. I had to create one,” the founder explains. “There were a lot of restarts and moments where I felt frozen or lost. But with incredible support from family and friends, I kept going.”
As with many startups, funding and resource access were among the biggest hurdles—until a familiar community institution stepped in to help.
A Credit Union That Listened
As Chairman of the Board of Trustees for a local fraternal order, Burien Aerie 3523, the founder had frequent contact with their neighborhood Burien Sound Credit Union branch.
“I was there often, doing transactions. The team was amazing—so one day, I asked if they offered any small business resources. That conversation changed everything.”
Through Sound Credit Union, Belmar secured a Small Business Administration (SBA) loan and a business credit card—a crucial turning point in the business’s journey.
“I had finally reached the point where I couldn’t move forward without funding. The team at Sound—especially Wendi and Stevie—walked me through everything. They kept me informed, motivated, and reassured. I’ll always be grateful for that.”
“What moved me most about David’s journey was the heart behind what he was building. So many of us have felt the weight of burnout and just learn to live with it—but not David. From the very beginning, working with him felt less like a loan process and more like a partnership. I’m so proud his journey and honored to have played even a small part in that.” — Wendi Plain, Small Business Loan Officer, Sound Credit Union
Funding That Fueled a Dream
The financing from Sound enabled Belmar to:
- Purchase all necessary diagnostic and clinical equipment
- Hire essential medical and administrative staff
- Begin building infrastructure for community programs and expansion
Today, the doors at Belmar are open—and welcoming patients who have often been waiting far too long to get the care and answers they deserve.
What’s Next for Belmar?
Looking ahead, Belmar is focused on:
- Reducing testing wait times
- Supporting healthier lifestyles through tailored programs
- Building community partnerships
- Expanding into new regions and underserved markets
With a mission rooted in quality care over quantity care, Belmar is reimagining how diagnostic healthcare is delivered—restoring dignity and decency in the process.
