Founder & CEO, Arena Care & Health
Dr. Omkar Vaidya, MD, Executive MBA (“Dr. V”), is the Founder and CEO of Arena Care & Health, a physician-led organization dedicated to providing high-quality, accessible, comprehensive, and community-focused care.
​
His vision is grounded in a simple belief: healthcare is a mutual privilege between patients and physicians. The best care is built on trust, accessibility, clinical excellence, advocacy, and a genuine commitment to doing what is best for the patient.
Dr. V is an American Board-Certified Internist, Critical Care Physician and Nephrologist. He brings more than 16 years of diverse clinical experience across internal medicine, outpatient, inpatient medicine, critical care, and nephrology.
Dr. V began his medical career in private practice, where he practiced for approximately six years in Kansas City before relocating to Boston. He worked in multiple aspects of clinical work Critical Care, Critical Care Nephrology, Nephrology, Transplant Nephrology, Primary Care. During Pandemic he worked in hybrid capacity and still works with Arena Health focused on providing specialty care to small hospitals in various states. Performing highly acute interventions to save lives - ECMO, Continuous renal replacement therapy, Mechanical Ventilatory support. After moving to Massachusetts, he continued caring for patients while working nights as a Hospitalist and Intensivist. He continued providing virtual care for hospitals as well.. So lot of hard work and busy days
In 2023, Dr. V ( Dr. Omkar Vaidya ) founded Arena Care ( Ambulatory Internal Medicine and Urgent Visits) in Boston as he could not find a provider to get care and this was a casual discussion while he was at gym while on a treadmill with sight of Boston Common with his friend.
The beginning was intentionally simple. Dr. V started as a solo physician with limited resources and without an established infrastructure or large support system. He worked long hours, cared for patients personally, and continued building the practice around a fundamental principle: serve patients to the best of your ability and continue improving every day.
What started as one physician's vision has steadily evolved into a broader healthcare organization focused on accessible, personalized, and comprehensive community care.
The office was first started at a small space at 65 Harrison Ave Boston and then expanded to 50 Congress street Boston. In 2026, Arena Care reached a major milestone with its move to a new state-of-the-art facility at 75 Kneeland Street in Boston. The new facility represents a significant evolution from the original solo practice and provides an environment designed to support expanded services, additional providers, advanced diagnostics, and a more comprehensive approach to patient care.
Arena Care also has a northern satellite center in Woburn and a southern location in Plymouth, Massachusetts, with the goal of bringing high-quality care closer to the communities it serves.

Critical Care Physician and Community Medicine
Alongside his outpatient practice, Dr. V continues to practice as an Intensive Care Physician at Beth Israel Plymouth. He particularly values his role in critical care because it allows him to care for patients and families during some of the most vulnerable and important moments of their lives.
For Dr. V, critical care is more than a clinical specialty. It represents the responsibility and privilege of being present when patients need their medical team the most.
His experience caring for critically ill patients has also influenced the way he approaches outpatient medicine. Years of managing complex illness, airway emergencies, ventilation, and life-saving procedures have shaped his belief that many health problems are best addressed before they become emergencies.
A Focus on the Whole Person
Dr. V's approach to medicine focuses on the intersection of mind, body, and medicine.
His clinical areas of focus include:
-
General Internal Medicine
-
Preventive Medicine and Health Enhancement
-
Kidney Health and Nephrology
-
Airway, Sleep & Breathing Disorders
-
Metabolic Health and Disorders
-
Chronic Disease Management
-
Complex Medical Conditions
-
Kidney Stones and Bladder Disorders
One area that has become a particular focus of Dr. V's practice is airway, sleep, and breathing health.
His interest in airway medicine developed naturally from his critical-care background, where airway management is an essential component of life-saving medicine. This experience led him to ask a broader question: How does the airway affect patients when they are not critically ill?
Rather than viewing sleep-disordered breathing solely through the traditional lens of CPAP therapy, Dr. V focuses on understanding the underlying contributors to airway and breathing problems and developing individualized solutions.
His approach may incorporate medical evaluation, sleep assessment, airway evaluation, ENT collaboration, and orthodontic/airway-focused care when appropriate. Through collaboration with ENT specialists ( Dr. Gulleth) and airway-focused orthodontic provider ( Dr. John Walker) , his goal is to understand the root causes and contributing factors rather than simply treating the symptoms.
A Philosophy Built Around Patients and Providers
Dr. V believes patients deserve to be heard, understood, and treated with respect.
He also believes physicians and healthcare professionals deserve to work in an environment where they are supported, respected, and able to practice medicine thoughtfully.
His philosophy is therefore centered on both sides of the healthcare relationship:
Patients first. Providers supported. Better care for the community.
Beyond individual patient care, Dr. V remains deeply committed to community health and health enhancement. He believes modern medicine should not simply respond to illness after it develops. It should also help people understand their health, identify risks earlier, and develop sustainable strategies for long-term wellness.
Education & Academic Medicine
Dr. V completed his training in Internal Medicine and Critical Care Medicine at the University of Missouri–Kansas City and Truman Medical Center. He subsequently completed advanced fellowship training in Nephrology at UT Southwestern Medical Center in Dallas and the Veterans Affairs North Texas Health Care System.
He maintains a Harvard Medical Faculty position and serves as Clinical Faculty at Boston University, where he continues to teach and mentor future healthcare professionals, including Nurse Practitioner and pre-medical students.
He also serves as a clinical preceptor for Nurse Practitioner students and trainees affiliated with Northeastern University, Simmons University, and Regis College.
Teaching remains an important part of Dr. V's professional identity. He believes medicine is not only about caring for today's patients but also about preparing and inspiring the next generation of physicians, advanced practice providers, nurses, and healthcare professionals.
For Dr. V, education is an extension of patient care: the knowledge shared with the next generation ultimately becomes part of the care delivered to future patients.

Advocacy & Leadership
Dr. V has served on patient-care review committees as a clinical expert, providing an independent clinical perspective on complex patient-care matters.
Throughout his career, he has maintained a strong commitment to advocacy — advocating for patients to receive appropriate and compassionate care while also recognizing that supporting healthcare professionals is essential to delivering excellent medicine.
His leadership philosophy is rooted in a simple principle:
The best healthcare environment is one where patients come first and the people caring for them are also supported.
From beginning Arena Care as a solo physician in Boston to developing a growing healthcare organization with multiple locations, Dr. V continues to build toward a long-term vision of accessible, comprehensive, physician-led, community-centered healthcare.
For him, Arena Care is more than a medical practice.
It is an ongoing effort to create a better relationship between patients, physicians, and the healthcare system — one patient, one provider, and one community at a time.
