Dental care in San Ramon led by Dr. Niko with 20 years of experience, same-day appointments, and a patient-first approach for every stage of life.
Dr. Niko earned his Doctor of Dental Surgery degree from the University of California San Francisco. He later continued his dental education by attending numerous workshops and dental institutes where he perfected his ability to perform preventive care at the exceptionally high level as well as specialties like restorative and cosmetic dentistry and implants.
He has spent the last 20 years perfecting his craft, achieving his certification in Invisalign® treatment, laser dentistry and Veneers®. Dr Niko enjoys spending time in Greece with his family, smoking and grilling meats as well as playing the trumpet. He volunteers as member of several local community groups here in the Danville, Alamo and San Ramon area.

From preventive care to full smile restoration, our San Ramon team provides everything your family needs under one roof.
Preventive care is the foundation of lifelong oral health. Our general dentistry services include comprehensive exams, professional cleanings, digital X-rays, fluoride treatments, and dental sealants, keeping your whole family's smiles healthy year after year.

If you have a cracked, severely decayed, or structurally weakened tooth, you already know it is not something you can ignore. You may feel pain when chewing, notice sensitivity to temperature, or see visible damage to the affected tooth. A broken tooth or failing restoration can make you hesitant to eat normally or smile comfortably.At Parthenon Dental, we provide same day dental crowns in San Ramon to restore strength, protect natural tooth structure, and return your smile to normal function in just one visit. In many cases, a dental crown procedure can be completed without the need for temporary crowns or multiple appointments.
We welcome children age 3 and older. Early dental visits build healthy habits, reduce anxiety, and set the stage for a lifetime of great oral health. Our gentle team uses simple explanations, positive reinforcement, and a kid-friendly approach to make every visit a good one.
Dental fillings are one of the most common and effective solutions for repairing teeth affected by decay, minor fractures, or wear. We use tooth-colored composite materials that blend naturally with your smile, restoring strength and preventing further damage in a single visit.
Dental implants are the gold standard for replacing missing teeth, restoring chewing strength, confidence, and long-term oral health. We review your medical history, take digital images, and create a customized plan. Healthy gums and adequate bone structure are all you need to get started.
Dentures are removable appliances designed to replace missing teeth and restore your chewing ability, speech clarity, and smile confidence — whether tooth loss resulted from injury, decay, or gum disease. Dr. Niko customizes each denture to ensure a natural appearance and comfortable, lifestyle-compatible fit.
Gum disease is one of the most common oral health issues affecting adults today. When bacteria accumulate along the gumline, the resulting infection can destroy gum tissue and supporting bone, leading to tooth loss if left untreated. We offer deep cleaning, scaling, and periodontal therapy to restore gum health.
Root canal therapy has a reputation it doesn't deserve. For most patients, the procedure is no more uncomfortable than getting a filling. We use modern techniques to relieve pain, eliminate infection, and save your natural tooth, helping you get back to your normal life quickly and comfortably.
Dental emergencies don't follow a schedule. If you're experiencing pain, swelling, a knocked-out tooth, or a broken restoration, call us immediately. Our San Ramon team does its best to accommodate urgent care the same day, because fast treatment can mean the difference between saving or losing a tooth.
We welcome children age 3 and older. Early visits build healthy habits and reduce anxiety. Preventive care, gentle cleanings, and simple explanations help kids feel at ease. Parents receive practical tips to keep little smiles strong between checkups.

I am very content with San Ramon Valley Dentistry! Dr. Nico treats his patients with much consideration and professionalism. He is very attentive to your case and gives you a clear explanation of the treatment needed. Dr. Nico’s staff is excellent. You’d be hard pressed to find RDAs as nice as Claudia and Yadi.

Just had my first visit with San Ramon Valley Dentistry today and was pleasantly impressed. I was referred to Dr. Niko by my previous Dentist who recently retired and being one who doesn’t always embrace change, I was a bit skeptical. When I arrived I was greeted by friendly staff, a very clean and safe environment with much better technology that I was accustomed to. Great overall and I will definitely stay the course with them!!
Dr Grasso has been my dentist since 1994 when I lived in Dublin. I moved to Sacramento in 2000 but I continue to drive to San Ramon for Dr. Grasso to take care of my dental implant needs. His chairside manner is excellent, his hands are light and gentle, he patiently explains procedures to me and answers questions in a way that I understand. His Office Manager runs the office efficiently, takes care of my insurance claims, explains my bill in relation to my procedures and patiently answers any questions I might have. His staff is always professional, warm and welcoming. I would never go to a different dental practice.
