A Physician Who Believes Movement, Food, and Daily Habits Are Medicine

Dr. Sarah Weinstein, DO, known to many patients as Dr. Sassy, has built a career around one clear idea: that people deserve care that helps them move better, feel stronger, and live healthier in a way that lasts. As a triple board-certified physician in Family Medicine, Lifestyle Medicine, and Sports Medicine, she blends scientific precision with practical, everyday guidance that patients can actually use in their real lives.

Today, she is the founder of CORE Sports Medicine and Lifestyle Medicine, a growing practice in Hopewell, New Jersey that reflects her belief that healing is not one-dimensional. It is physical, nutritional, emotional, and behavioral. Her clinic combines advanced nonsurgical treatments with lifestyle-focused medical care, serving everyone from everyday walkers to competitive athletes who want to stay active and pain-free.

Her work, her warmth, and her whole-person philosophy have earned her national recognition, including being named one of MSN’s Top 10 Health Voices Helping People Feel Better and Digital Journal’s Top 10 Health Experts Making a Real Impact in Today’s World. But for Dr. Weinstein, the real highlight is seeing a patient move without pain for the first time in years.

A Childhood Shaped by Movement, Curiosity, and the Outdoors

Dr. Weinstein’s relationship with movement began long before her medical career. She grew up on a farm surrounded by fresh produce, long days outdoors, and an active, hands-on lifestyle. She loved sports, physical activity, and the feeling of being strong, fast, and capable. But like many athletes, she faced her share of injuries and health setbacks.

Those early experiences left a lasting mark. They showed her what it feels like to lose something you love because your body is not cooperating. They also gave her a deep sense of empathy, something that would become central to the way she practices today. When a patient says they want to get back to running, lifting, walking, or simply keeping up with their kids, she understands exactly what that desire feels like.

Building a Medical Career That Mirrors Her Values

Her medical training has taken her across multiple disciplines, but sports medicine and lifestyle medicine were a natural fit. In her years working in large medical groups and leading a multidisciplinary practice, she saw how often people were rushed from one appointment to another without feeling seen, heard, or understood.

At the same time, she saw how powerful lifestyle changes could be in reducing pain, improving recovery, and boosting long-term health. Nutrition, sleep, stress, movement, and strength training all play a massive role in how the body heals, but they are rarely discussed in a traditional exam room.

She wanted to change that — and eventually she did.

In November 2024, Dr. Weinstein opened CORE Sports Medicine and Lifestyle Medicine, a space designed intentionally for collaboration, curiosity, and trust. Her clinic offers ultrasound-guided sports medicine procedures, shockwave therapy, PRP, movement assessments, lifestyle counseling, and long-term support, all tailored to the patient’s goals.

A Physician Who Teaches People How to Heal, Not Just Where It Hurts

What sets Dr. Weinstein apart is her blended approach. She uses the most advanced sports medicine tools available, but she also asks questions that go well beyond the injury itself.

How do you sleep?

What does a normal week of food look like for you?

How are you managing stress?

Do you feel supported in your goals?

These are not small details. In her view, they are the backbone of long-term recovery.

Her goal is simple: to help patients understand their own bodies in a way that empowers them. Healing is not passive, and she believes people deserve to be part of the process rather than bystanders in it.

The Heart of Her Practice: Community, Connection, and Movement

Dr. Weinstein believes that medicine can extend far beyond the exam room. She leads a popular Walk With a Doc chapter, walking monthly with patients, families, and community members. They discuss health, mobility, sleep, nutrition, and daily habits in a relaxed, welcoming environment.

She also teaches a “Full Body Strength” exercise class at a local gym, blending science with accessibility. Patients see her as a physician, but also as someone who practices what she teaches. It adds an authenticity that cannot be replicated with quick appointments or rushed advice.

Her volunteer work at a community clinic reflects the same commitment, ensuring people without insurance still have access to compassionate, personalized care.

The Story Behind Her Bold Professional Leap

Stepping out on her own and opening CORE was a leap of faith. Like many physicians, Dr. Weinstein never received business training during medical school, so building a practice from scratch required determination, curiosity, and a willingness to learn quickly.

But she knew it was the right move. She wanted a place where she could give patients time, education, and long-term support. She wanted a practice that reflected her values, not one bound by rushed visits and quick fixes.

The result is a clinic that feels deeply personal, where patients know they are respected as individuals and not just symptoms.

A Vision for the Future, Where Healthcare Feels Personal, Empowering, and Human

Dr. Weinstein has big plans for CORE. She envisions a full performance and wellness center that brings sports medicine, fitness, rehab, nutrition, cooking education, and testing under one roof. A place where lifestyle is taught as a core part of care, not an afterthought.

She also plans to expand her speaking and teaching engagements, helping both patients and fellow physicians understand how transformative lifestyle medicine can be.

Her mission remains steady, to help people move, feel, and live better — no matter their age, injury, or starting point.

Why Patients Trust Dr. Sarah Weinstein

Her patients often say one thing repeatedly: “She listens.” In a world where people feel unheard in medical settings, that matters.

Add to that her dual expertise, her athlete’s perspective, her community involvement, and her approachable personality, and it becomes clear why she is becoming a trusted voice in modern wellness.

Her approach is not about perfection or pressure. It is about progress, confidence, and possibility.

And for the thousands of people who want to live active, mobile, pain-free lives, that message is exactly what they have been waiting for.
