Harshali P
"Dr. Varun Prabhavalkar was my mentor for the course of Implantology conducted in association with Osstem. His knowledge, clarity, and passion for the subject were truly inspiring, and I am extremely grateful for the time and effort you devoted to educating us. Your hands-on demonstration and detailed guidance throughout the procedures were invaluable. The way you patiently corrected mistakes and ensured we understood every step made a lasting impact on our learning and confidence. Although, the course duration was short, but you managed to cover a vast amount of material with great clarity. As a surgeon, it's clear he is highly skilled, he shared a few of his clinical cases, which were executed with excellence and precision. It was truly inspiring to see his work and learn directly from him. I feel fortunate to have been trained under Dr. Varun Prabhalkar. Thank you once again for sharing your expertise so generously. It was an absolute privilege to learn from you, and I look forward to applying your teachings in our clinical practice."

"Always an exceptional experience at Dr. Prabhavalkar's One Sigma Dental. The level of expertise, care, and professionalism is truly outstanding. Every procedure is carried out with precision, attention to minute details, and a deep focus on patient comfort, making the entire journey smooth, painless and stress-free. What truly sets them apart is the phenomenal post-surgery care. Thoughtful, attentive, and incredibly reassuring. Highly recommend for anyone looking for world-class dental care."

"You are subjected to a X-ray scan on your first visit itself. I highly recommend it to everyone. It showed decay in one of my molars, that wasn't visible to the bare eye. When they were healing that molar, they proactively told me and took action on the adjacent tooth too, in the same session. Preventing me from so much future pain for both teeth. He also did an implant for me ~13 years back, which has not caused even a slight problem so far. They use top-notch tech like microscope for Root Canal, digital scanning for teeth measurement and 3D printing for the teeth model. I have been going to them for 25 years now, it has been a personal inspiration to see them evolve from a compact area to the luxurious place they have now. They are a great team with seamless communication, where Dr. Varun and Dr. Nikhil do the heavy-duty, intense operations while Dr. Anushree does the finesse work and completes the procedure. The great ambience and their prompt receptionist, is just a cherry on top."

"I have known Dr. Prabhavalkar since I was a child and have trusted him ever since. He is an amazing dentist with exceptional skills, and every treatment is done with great care and precision. Even though I don't live in Mumbai anymore, I always make it a point to visit him whenever I'm there because he is the only dentist I trust. His staff is also wonderful friendly, caring, and welcoming. I highly recommend Dr. Prabhavalkar at Kohinoor Plaza, Dadar, to anyone looking for excellent dental care."
