Patient Reviews

  • "I have been led to Dr DaCosta 3 separate times in the past 15 years. Each time he was informative, compassionate and reassuring. He describes what is medically happening, and presents possible treatment plans. He is the best physician I have ever seen, and I trust him with my healthcare. Also, all of the staff are equally kind, timely and courteous. Sincere thanks 🙏🏻 😊"

  • "I want to express my sincere appreciation for Dr. DaCosta . He cared for my late wife with compassion and dignity, and now he continues to care for me with the same dedication. His presence during some of the most difficult times in our lives gave us both comfort and confidence. What I value most about Dr. Dr DaCosta is the way he combines medical expertise with genuine kindness. He listens with patience, explains with clarity, and treats his patients with respect and empathy. His bedside manner has always made me feel seen and cared for, not just treated as a patient. I feel truly fortunate to be under his care and grateful for the support he has provided my family and me. Physicians like Dr. DaCosta make a profound difference, and I wanted to take this opportunity to recognise his outstanding work and the compassion with which he practices medicine."
