A medical student using his own failure experience for the betterment of life of others, story of Zachery Dereniowski
Zachery Dereniowski, a medical student whose purpose of life is to empower others. The 27-year-old is exploring the world, discovering his passion and is using his own life experiences for the betterment of others. In his words, “I think life is not about you or me. I think life is about the footprint we leave in bettering the lives of others.”
Zachery who is born in Windsor, ON Canada, is a medical student at the University of Sydney in Australia pursuing the Post-Graduate Doctor of Medicine Program. He pursued Bachelor of Human Kinetics from the University of Windsor, Windsor, ON and Post-Baccalaureate in Pre-Medical Studies from Lawrence Technological University, Southfield, MI.
A dual U.S. and Canadian citizen, he has experienced the life of a busy border city and observed the difference between basic health care facilities provided. In Canada, the facilities are affordable but are not easily accessible whereas it is the other way around in the US.
Inspired by Kobe Bryant, he has a keen interest in playing basketball and loves staying active, the outdoors, and working out. He considers himself a scary movie buff. He indulges himself in spontaneous road trips. He says after exploring the natural beauty of New Zealand, it is his favourite holiday destination.
We all have our share of struggles. So does he. It was difficult for him to score well on the MCAT and get into a extremely competitive medical program after he underachieved in college. In the first year of college he scored 0.59 GPA, as a result, he was Required to Withdraw from the Biochemistry program. He pumped inspiration in himself with this failure and several lessons learnt. He completed his studies and scored a 4.0 GPA over his last 9 consecutive semesters and over 510 in MCAT in his first attempt.
Zachery is now a motivational speaker. He has been working as an MCAT tutor and wants to continue to help educate, empower, and mentor-driven students wanting to maximize their MCAT scores.
At present, he is creating content to empower people, especially once who are suffering from mental health issues. He is one of TikTok’s top mental health advocates with over 400K followers. He has been interviewed by the Sydney Herald regarding his platform and giving those facing mental health issues a voice. He wants to continue to spread awareness and wants to tell people that they are not alone and worthy of a better life. He looks forward to supporting people and educating them for using their voice for the betterment of their lives.

Kat Marie Alvarez: Where Innovation Meets Regulation
Regulation is often thought of as a limitation, yet in healthcare, it also serves as a foundation for building models that endure. For Kat Marie Alvarez, Founder and CEO of KATALYST & CO, the framework of rules established by agencies like CMS (Centers for Medicare and Medicaid) and the OIG ( office of the Inspector General) create opportunities to design systems that are compliant, ethical, and transformative. Her approach demonstrates that regulation can be a platform for innovation when it is interpreted with both technical rigor and vision.
Kat’s 25-year career reflects this philosophy. A former nurse who advanced into executive leadership and strategy, she has led $2.7B+ P&L operations, advised on over $5B in healthcare transactions, and guided value based organizations including Innovacare, Cano Health, WellMed, Centene, and Humana through periods of exponential scaling. Her perspective combines clinical, financial, and regulatory experience, giving her a unique ability to design structures that support integrity and accountability while driving measurable outcomes.
Turning Statutes into Strategy
For Kat, regulation serves as a framework for building smarter and more ethical models. She interprets CMS guidance and OIG rules as levers for innovation, using them to advance integrity and accountability. With the CMS V28 risk adjustment model, Alvarez refined coding practices, strengthened clinical documentation, and structured risk frameworks that reward accuracy and elevate standards of care. In addressing RADV audits, she crafted strategies that protect stakeholders while keeping patient outcomes at the forefront. She aligns compliance, cost, and care in equal measure. Her current work as a contributor to the CMS IDea Challenge, an initiative focused on strengthening the foundation of trust in our system, further echoes her commitment to advancing regulations in ways that unlock innovation while safeguarding the integrity of care.
Her interpretive approach brings discipline and vision to every challenge. She engages stakeholders to redesign workflows that meet regulatory requirements and enhance the patient experience. Each policy becomes a mechanism to strengthen accountability and operational precision, shaping a system that is both compliant and humane.
Innovation Built Within Boundaries
At KATALYST & CO, this interpretive approach is carried into every project. Kat has integrated predictive analytics and AI-driven tools into care models, with safeguards that ensure interventions remain clinician-led and ethically sound. For example, AI flags in chronic disease management are connected to human-led actions that improve patient care. The result is a model that benefits from technology while preserving accountability and clinical integrity.
Staffing and infrastructure provide another example of her philosophy in action. By leveraging offshore BPO operations in Latin America, Asia, and Eastern Europe, KATALYST & CO extends capacity for health plans and providers. These expansions are carefully designed to meet data security, licensure, and jurisdictional requirements, ensuring that global reach is paired with local compliance. It is a system that balances scale with responsibility.
The Art of Influence Through Alignment
Kat often describes her role as translating complexity into clarity. Whether she is working with payers, providers, or investors, she builds consensus by grounding ambitious strategies in the language of statute. Value-based care models, utilization management programs, and clinical frameworks are designed to prove compliant ROI for stakeholders while maintaining patient focus.
Her approach begins with people. In integrations, partnerships, and platform builds, she respects legacy strengths, listens to frontline voices, and creates systems that are not only efficient but also trusted. This ensures that compliance does not feel like restriction, but like a structure that supports innovation and adoption.
Redefining the Future of Compliance and Care
KATALYST & CO is scaling with $10M in initial funding, expanded international operations, and a growing advisory portfolio. Under Kat’s leadership, the firm is showing how regulation can be a foundation for both innovation and durability. She demonstrates that lasting progress in healthcare is achieved by leaders who know how to design systems that are bold, ethical, and deeply human.
By approaching regulation as a guide rather than a limitation, Kat Alvarez is building models that prove compliance and innovation can move forward together. Her formula ensures that the future of healthcare is shaped not only by ambition, but also by trust and responsibility.
