Welcome to a Different Kind of Cardiology Practice
Christoph Sossou, MD
At Ambulatory Cardiovascular Center, you’re not just another patient — you’re family.
This isn’t just another cardiology office.
This is the practice I always wished existed when my own family needed a cardiologist.
My name is Christoph Sossou, and I opened Ambulatory Cardiovascular Center because I was tired of watching good people get lost in the system — waiting weeks for an appointment, seeing a different doctor every visit, and leaving more confused than when they arrived.
I trained at some of the best programs in the country, published research in esteemed peer-review journals, evaluated and treated hundreds of patients, including heart transplant patients, and performed hundreds of catheterizations and various minimally invasive cardiovascular procedures.
But the moment that changed everything was when my own grandmother had chest pain on a Friday evening. She called her cardiologist’s office — and never got a callback. That night I promised myself: “When I open my own practice, no patient of mine will ever feel abandoned.”
That promise became this office. Here, you have my cell phone number. You see me — not a nurse practitioner, not a fellow, not a new face every visit. If you’re worried at 8 PM on a Saturday, you text or call me directly. That’s not “concierge” — that’s just being a doctor.
A True Partnership with your Primary Care Team
I place the highest importance on value-based, collaborative care and consider myself a true partner with you—the patient’s primary physician—in delivering the best possible outcomes.
At Ambulatory Cardiovascular Center, LLC, I believe the best cardiovascular outcomes are achieved when the cardiologist and primary physician work as partners — not in parallel.
As your patient’s cardiologist, my commitment to you is simple and unwavering:
You will always have direct, personal access to me — by cell phone, text, or secure messaging — for any question, urgent concern, or care coordination need.
Every consultation note, test result, procedure report, and treatment plan will be sent to your office (via your preferred method) within 72 hours of the visit. Same-day verbal updates are provided for urgent evaluations.
I practice value-based, evidence-based cardiology with an emphasis on clear communication, shared decision-making, and keeping you fully in the loop as the quarterback of your patient’s overall health.
My role is to provide expert subspecialty care while strengthening — never replacing — the trusted relationship you have built with your patient.
I look forward to partnering with you to deliver the highest-quality, most coordinated cardiovascular care in Essex County.
