I recently completed my Invisalign treatment at Diablo Hills Dental "Excellence" and I feel it's…read moreimportant to share my experience. While I had high hopes for my treatment, I encountered several serious issues that left me feeling frustrated and undervalued as a patient. My treatment began on July 12, 2021, under Dr. Charlie Palayno, but I was later reassigned to Dr. Nick. During a recent appointment, Dr. Nick acknowledged that communication needed improvement but assured me that my treatment would proceed smoothly. However, in my next visit, Dr. Charlie Palayno informed me that my treatment had been deemed too prolonged and that he would not be continuing it. When I requested to review my contract, I was met with a dismissive response. He even yelled for someone to "deal with her" when he refused to continue my treatment, which was incredibly unprofessional and left me feeling scared. Throughout this process, I never received any apologies for the distress I experienced. I attempted to explain that my delays were due to personal circumstances affecting my dental hygiene, but my concerns were met with frustration rather than understanding. Additionally, I faced issues when trying to order a new retainer after losing mine. I was initially told I couldn't place an order due to a charge on my family account that I clarified was not my responsibility. After speaking with a manager, I was eventually allowed to proceed with my order, but it felt like pulling teeth (pun intended). I also can't shake the feeling that I was treated differently during my treatment due to my age, which adds to my disappointment with this practice. I understand that being culturally competent can be challenging in today's world, but I believe it is essential for providing quality care. During a meeting with management to discuss my concerns, I clarified that I had not yelled at any employees; rather, I was expressing my frustration with how I felt I was being treated. I pointed out that the practice was charging me $485 for what seemed unjustified, and I made it clear that I found this unacceptable. After experiencing numerous issues throughout my treatment, I felt it was difficult to remain courteous. While management seemed to empathize with my situation, I left feeling perplexed by the lack of accountability for the problems I encountered. Last week marked my final appointment, and I was unaware it was my last until after leaving. Shortly after, I received a call stating that the practice would be discontinuing their services with me due to our previous conversation. I have since requested this decision in writing for my records. While I appreciate the initial care I received, the overall experience has been disappointing and distressing. I hope the practice can improve communication and treatment protocols for future patients. Plenty of places need to get shut down. They remain open. That's life. (Also a lot of these good reviews are because they offered whitening pens to guests if they left a review. I have heard terrible stories about this place from many)

Very professional staff , welcoming , friendly , efficient and on time , no waiting . Dr Palanos…read more(twins) absolutely the BEST -I HIGHLY recommend taking any dental issues to this fantastic practice. Jeff K
