What Patients Say

  • I 100% recommend Richard ORRICK and his staff! When I was pregnant I had to get a root canal. I was in excruciating pain and they squeezed me in on the day that I called. From his staff at the front desk, his dental assistants, to Richard Orrick himself, I received excellent care. They were patient and very focused on what was best for me. I maxxed out the limit on my dental insurance and his team worked with me help cover the remaining costs. My root canal procedure went quickly and smoothly. I have been to other dentists and specialists and this was by far the most positive experience I’ve had. I will never forget how much pain I was in before the root canal procedure and I’ll never forget how much they helped me! God bless!

  • Dr. Orrick has come to my rescue for a fourth time now. Staff from the front to the back and every station in between is the best in the business. I’ve been made to feel like a VIP every time I have needed their services. Thank you, Doc & staff!

  • Dr. Orrick and staff are fantastic. The office answers the phone and works to the best of their ability to get you seen ASAP. The dental work was done quickly, calmly and most importantly pain free. I'm so glad I chose Gateway Endodontics.

  • Update: Years later now and I have indeed gone back for another root canal! It was excellent! Fit me in right away and it was fast and pain free! I HIGHLY recommend this office and Dr.Orrick, his whole team is amazing! I wouldn’t go anywhere else! I had a lovely root canal done here and I would do it again! Staff and the Dr were friendly and professional, the price was reasonable and the gas must be top notch because I didn’t feel a thing! Highly recommend! Will definitely go again the next time my teeth betray me!

  • I agree with other great reviews. I was able to get an appointment to evaluate 3 teeth quickly. Dr. Orrick explained everything and recommended a treatment plan. There was no pressure to get unnecessary and expensive treatment. His office staff worked with my insurance to get the most of it.
