Yes, my initial appointment was made over six months ago. I made it. I didn't get any phone calls. I called Hackensack and they said you don't have an appointment. I don't know how that happened. So I made another appointment in two weeks. And nobody called me before that appointment to remind me of my appointment. So I think they need better follow-up with the patients in making sure that they have appointments when they do, because twice now they didn't do it at all.

My doctor was the best. I usually have a massive amount of anxiety visiting doctors, but this time I had such a pleasant experience that I was anxiety free throughout the whole visit. Best doctor experience I have ever had.

Karla oliveri is the absolute BEST! She is patient, kind, knowledgeable, listens and comprehend, she understands my needs and concerns. Karla always goes above and beyond. She explains everything to you in a way that you understand. She gives advice to support you mentally and physically; Karla is safe and provides a safe space. I've cried in her office amd she was empathetic. Karla feels like family!!! I would recommend her to the world! The medical field NEEDS more people like her!!! I hope she mentors in coming nurses and doctors or anyone who comes in contact with patients! I love Karla! She is simply THE BEST!!!

I recently had the privilege of seeing Karla Oliveri, APN, for my Long COVID health issues, and I can confidently say it was one of the most thorough, validating, and intellectually engaging healthcare experiences I've ever had. Karla dedicated a full two hours to our consultation-something almost unheard of in modern clinical practice. During that time, she actively listened to every one of my symptoms, concerns, and experiences without interruption or judgment. Her empathy was matched by her professionalism, and she made it abundantly clear that I am not alone in facing these post-viral challenges. That validation alone was a critical part of the healing process-something too often overlooked in the care of chronic and poorly understood conditions like Long COVID. She took the time to explain the pathophysiology of my symptoms in extraordinary detail, translating complex mechanisms into clear, medically grounded language that respected my intelligence and curiosity. From neuroinflammation and autonomic dysfunction to immune dysregulation and metabolic impairment, Karla didn't just offer explanations-she taught, engaged, and informed. What stood out even more was the comprehensive and evidence-informed holistic treatment strategy that was developed. Rather than offering generic advice, Karla integrated current research with a detailed understanding of my symptom profile, medical history, and disease progression. She articulated each phase of the plan with clinical precision-clarifying objectives, expected responses, and contingency adjustments-instilling a clear sense of structure and therapeutic intent. Her methodical approach not only demonstrated deep clinical expertise but also restored a sense of agency and optimism in managing the complexities of post-viral dysregulation. Karla Oliveri is a rare kind of provider-one who blends scientific rigor with deep compassion. She is not just treating a condition; she is treating a human being, with all the nuance and complexity that entails. I left her office feeling heard, empowered, and, most importantly, hopeful. If you are struggling with Long COVID or any chronic post-viral illness and want a provider who will meet you with empathy, intelligence, and clinical excellence, Karla is the gold standard

Dr. Oliveri is professional, taking time with every aspect of my care. I have the utmost confidence in her.

Karla Oliveri is fantastic - very professional, caring, and informative. She has helped me tremendously. Please make sure she is on the list of providers for the office's staff as the answering service is still confused when I call, stating that she is not part of the practice. This is the only inconvenience with this service overall.

She went above and beyond
