    I've said it before and I'll say it again, Dr. Mak is the absolute best dentist I have ever been…read moreto. Every interaction I have with him is positive. He is funny and light hearted and he always makes me feel better when I'm having an issue or I'm stressed about any dental work I'm going to have done. He does amazing work. He's done an implant and a bridge for me and he always honors his work. I've been going to him for about five years now, even my kids look forward to seeing him at their routine cleanings.

    I was referred to this office by my regular dentist for periodontal work. Due to limited…read moreavailability, it took about four months to be seen. The procedure was a gum/skin graft on my front teeth. Before the procedure, there were already billing issues. The office attempted to charge more than what my insurance (Delta Dental) indicated would be covered. This resulted in extensive back-and-forth to ensure insurance was applied correctly and billing codes were entered properly. We eventually agreed on a total, and I paid a deposit. On the day of the procedure, I paid the remaining balance we agreed to and signed for. I returned for two follow-up visits to confirm healing and had no further treatment with this office. One full year later, I received a bill claiming I owed $850, with no clear explanation. When I contacted the office, I was told the billing codes had been entered incorrectly and that I now owed the difference. Delta Dental confirmed the office had used the wrong billing codes and advised them to correct the submission so it would be covered. The office refused to fix the coding and instead threatened to send me to collections. After continued disputes, the balance was lowered to $450, though we still did not believe we owed anything. To avoid collections, we set up a payment plan ($50 down and $115 monthly). The balance was paid in full. Despite this, I was later sent to collections "by mistake" and told the office would correct it. Then, I received another bill for $115, which they claimed was due because they had "forgotten to include a payment." This office is disorganized, aggressive with billing, and unwilling to take accountability for their own errors. The constant changes to what was owed, threats of collections, and lack of transparency made this an extremely stressful experience. Proceed with caution. I would not recommend this office.
