About Heart of Chelsea

Dr. Marc Siebert is the owner and medical director of the Heart of Chelsea Animal Hospital. A native of New Jersey, Dr. Siebert opened Heart of Chelsea Animal Hospital as a one-doctor practice in 1999; it has since grown to a five-doctor practice supporting Chelsea, West Village, Greenwich Village, and Hudson River areas. Our warm and friendly neighborhood location sits between midtown and lower Manhattan, New York. Additionally, we have just opened the Lower East Side Animal Hospital, which provides the same outstanding veterinary care and serves Manhattan’s lower east side.

Heart of Chelsea Animal Hospital strives to provide the highest standards of pet health care coupled with the ultimate client experience for you. Our facility hosts the latest technology for diagnostic and surgical procedures. Additionally, we offer holistic medicine options such as acupuncture, homeopathy, and herbology.

Heart of Chelsea Animal Hospital is accredited by the American Animal Hospital Association (AAHA). The mission of AAHA is to establish the gold standard for veterinary excellence, and our accreditation is a reflection on the level of service and standard of care that we provide. We are one of only three clinics in Manhattan to achieve this voluntary accreditation, which includes approximately 900 quality standards in veterinary care.

Our experienced veterinarians and licensed veterinary technicians have the skill, compassion, and client-focused attention to detail that sets us apart. We value education and seek opportunities to further our education to provide you and your pet with the latest in veterinary health care. We enjoy sharing our knowledge and partnering with you on your pet’s health.

We are accepting new clients and offer a client referral program to reward our clients for assisting us in our mission to provide the ultimate experience for our clients and their pets. If you aren’t completely satisfied, we aren’t completely satisfied. Please contact us to schedule an appointment or stop in to visit our facility.
