About Complete Dental Centers

One trusted dental group. Four Southern California offices.

Complete Dental Centers is the group behind four dental practices that many patients already know by their own names: Beachside Dental Group and Pacifica Dental in Huntington Beach, Marina Dentistry in Marina del Rey, and Rio Hondo Dental Group in Downey. The group was founded by Dr. Sameer Aljanedi, DDS, and serves patients across Huntington Beach, Downey and Marina del Rey.

What “complete” means

Complete means the full range of dentistry under one group — from a routine cleaning to full-arch implant restoration.

Across the four offices, the group's treatment menu covers general and preventive care, children's and family dentistry, restorative work such as crowns, dentures, and root canal therapy, dental implants including All-on-4 full-arch treatment, Invisalign and orthodontics, cosmetic dentistry, gum care, sedation, and emergency visits.

Not every office offers every treatment. Each location page lists what that office provides, and every service page shows which offices offer it. The practical benefit of a group this size: if your needs go beyond what one office provides, the answer is usually another chair in the same family — not a referral into the unknown.

The four offices

Four practices, three areas of Southern California. Each keeps its own name, its own team, and its own phone number.

• Beachside Dental Group — 18800 Main St, Ste 110, Huntington Beach. (714) 842-6151.
• Pacifica Dental — 18800 Main St, Ste 110B, Huntington Beach. (714) 848-8211. Same building as Beachside, in its own suite.
• Marina Dentistry — 4292 Lincoln Blvd, Marina del Rey. (310) 578-5000.
• Rio Hondo Dental Group — 8514 Paramount Blvd, Downey. (562) 928-5559. Se habla español; Denti-Cal and Medi-Cal accepted at this office.

Founded by Dr. Sameer Aljanedi, DDS

Dr. Sameer Aljanedi, DDS founded Complete Dental Centers, and his name appears across all four practices. His profile page holds the verified details.

How the group is organized

Each practice operates independently. That is worth saying plainly, because it affects the details that matter to your wallet and your schedule:

• Membership plans use the same yearly prices at every office ($199 / $299 / $399); what each plan includes differs by office.
• Financing partners differ by office — each practice works with its own roster of third-party lenders.
• Insurance policies differ by office. Rio Hondo in Downey is the group's office for Denti-Cal and Medi-Cal patients; for any other coverage question, the surest answer comes from the office you plan to visit.
• Hours differ too — some offices publish them and some confirm by phone, so the front desk is always the final word on scheduling.

If anything on this site ever differs from what a practice tells you directly, go with the practice — policies are set office by office, and their answer is the current one.

Where to start

Browse treatments, compare the four offices, or read what a first visit looks like. When you're ready, request an appointment and choose the office that suits you — or just call one. Either way, a person at the practice takes it from there.
