Perio & Implant Center Silicon Valley

I had a wonderful experience with Dr. Pechak and I am truly grateful for his care. From the moment he walked in, he was kind, patient, and extremely thorough. He took the time to examine my concerns carefully and explained everything in a way I could understand. I truly appreciated that he did not rush me, and he addressed every question with honesty and compassion. What impressed me the most was his clinical judgment. Instead of recommending unnecessary procedures, he focused on conservative, thoughtful treatment. He suggested a cleaning for the surrounding teeth and advised performing an RT test and a reverse-torque test to assess the health of my implant — exactly the careful, evidence-based approach I was hoping for. His recommendations aligned perfectly with my goal of preserving my implant and avoiding unnecessary surgery. It is rare to find a doctor who combines such technical expertise with warmth, honesty, and integrity. I left the appointment feeling informed, reassured, and confident that I am in excellent hands. Since this was my first visit to the office, I also want to mention how cheerful and welcoming the staff were. They made the entire experience even more comfortable. I highly recommend Dr. Pechak and his team to anyone seeking a knowledgeable, skilled, and truly caring implant and periodontal specialist.

I'm not sure what happened to this place, because I've been going here for years, but the last time I showed up I was informed I had an outstanding balance due. When I asked what this was for I was told that the last cleaning was $100 more than I was charged at the time of service. I was also informed that I owed money for multiple dentist exams. When I told the receptionist I hadn't seen the dentist in years he seemed confused. The only comment made was that there were no notes in my chart from the dentist so maybe I was right. Then I asked if they could look up my insurance and they said only if I had my card on me. I have had dentists look this up online before so I was shocked at how cold and unhelpful they were. When I finally got back to the hygienist I asked if I could speak to a manager. Someone came halfway through my exam and said they didn't have time to meet with me, but would audit my account and get back to me. When I checked out the front desk had somehow managed to find my insurance without a card. There was no apology for misunderstanding. No explanation for the multiple exam fees I was going to be charged that never happened. Nothing was said about why the last cleaning wasn't collected in full at the time of service. 2 weeks past and I didn't hear back so I called and asked for a follow up. The same receptionist called me back and said I owed $200 for an exam fee back in 2024 with a dentist who ended up cleaning my teeth. I had no idea I was being charged for an exam at the time, nor was I told after the visit. I'm unsure why the lack of transparency around fees and why they are deciding to charge me now for something that happened over a year ago, but needless to say I won't be returning. Proceed with caution.

I recently had a dental bone graft done with Dr. Pechak and the entire experience was excellent. The doctor explained every step clearly, was patient with my questions. Dr Pechak was extremely skillful and gentle during the procedure, and the dental assistants were attentive to my comfort, the procedure was smooth and painless. Recovery has also been very good, and the follow-up care has been thorough and reassuring. Thank you to Dr. Pechak and the team for making the experience so easy.

I had a gum contouring with Dr. Pechak, and I’m very happy with the result. The process was smooth, precise, and comfortable. My gum line looks much better now, showing more of my teeth. Excellent work and professional care from the team.

I find it very surprising that a clinic as established as this one doesn't have a process in place for when the insurance claims are not processed properly. It really is not that hard. Making honest mistakes is one thing, but not admitting or owning up to it is truly despicable and in bad faith. Really makes me wonder how many other patients had to pay cash price for services that would've been covered if insurance claims were processed properly. I had to find this out myself about my claims. When I called the clinic I was told that the billing team would refile the claims. I followed up weekly for about a month with the office staff giving me obscure answers. I ended up calling the insurance myself to find out what the issue was. I also found out that the clinic did NOT resubmit any claims as they said they would during this entire month of my back and forth with them. I had to call the clinic back with the exact instructions and ensure they have the billing team cc me when it's done to eventually get the claims reprocessed correctly. Two months passed where I did call the office once to follow up on the reprocessed claims with no further updates from them. I eventually saw through my insurance portal that the office had overcharged me for the procedures and owed me money after insurance payout. Because of how unreliable my follow-up calls with them have been, I waited until my final in office appointment to ask about this. After my appointment was done, I was taken into an office space with Melissa. And this is where it gets crazy. Melissa printed out some paperwork to review the billing with me, and in the end said "yep you're all good to go!" I pointed at the final balance on one of the papers and asked whether the -$800 balance shown is money owed to me. Melissa immediately says no, they're waiting on some resubmitted claims since they always resubmit claims twice when they're rejected and pointed at a random obscure line item. Lady please. Look at the amount of work I went through to get them to resubmit my unprocessed claims. And now she's claiming that they reprocess denied claims twice? Don't make me laugh. This clinic simply does not have the capacity nor the good intention. Melissa was also unable to answer when the claims were even resubmitted and told me to wait an arbitrary 2 weeks for an answer. Mind you it had already been 2 months since anything was last processed through insurance, and 3 months since my last procedure with them. At one point Melissa even tried to take back some paperwork she gave me and said they were irrelevant. She also tried to gaslight me by telling me multiple times "I don't know why you're so mad! Your insurance did so well! You don't owe us anything!" When they literally owe me $800 after insurance payout. Hello?! She ended up taking me to her computer outside in the hallway by the waiting area to print out some more things to show me. The paper she printed also showed a -$800 balance and she legit said "oh I don't know why this is here" like it misprinted and she's confused. At this point we were in a mild shouting match and the whole office could hear. I kept calling her out on her BS and she would just continue to lie to my face. I honestly felt like I was gonna have a stroke if I kept talking to her so I left. I later did confirm with insurance that there were NO refiling of any claims as Melissa had claimed and was eventually able to get the $800 refunded back from the clinic. TLDR: AVOID THIS CLINIC. The office staff/billing department is incredibly incompetent and dishonest. Melissa is a gaslighting and deflecting pathological liar. You will likely be overcharged for the service so be vigilant. Log in to your insurance portal and make sure the claims are processed and the clinic pays you back for the amount they overcharge. Keep a log of all your calls/encounters with them and know the names of every person you speak with. Be prepared to advocate for yourself because this clinic will not.

Consistently EXCELLENT service. The appointment scheduling and status notifications are great. The staff is welcoming and helpful. Dr. Pechak is absolutely superb. I highly recommend him!!!!

My experience with Dr. Pechak and his entire care team in Sunnyvale has been absolutely outstanding, and I wholeheartedly recommend them for any periodontic needs. From the very first appointment, I was impressed. The initial evaluation was incredibly thorough, and Dr. Pechak took the time to explain my situation and the proposed treatment plan in a way that was clear, concise, and easy to understand. He has a very welcoming demeanor and patiently answered all of my questions, which immediately put me at ease. It's evident that he is not only an expert in his field but also genuinely cares about his patients' understanding and comfort. The periodontal procedure itself was managed with the utmost professionalism and care. Everything went very smoothly, and the team worked together seamlessly to ensure I was comfortable throughout the process. The high standard of care didn't stop there. The aftercare instructions were detailed and clear, and the follow-up appointments were diligently scheduled and managed. The entire team, from the front desk to the dental assistants, is incredibly friendly, warm, and professional. They create a positive and calming atmosphere, which makes a significant difference. If you are looking for a knowledgeable and caring periodontist with a fantastic support team, look no further than Dr. Pechak's practice.
