This was the easiest, most painless dental experience I have ever had. The lady at the front desk is THE NICEST and so helpful! This was my first root canal and I was terrified & Dr. Orrick & his assistant made me feel at ease and the whole process was quick and painless!

Dr. Orrick and his staff were awesome. I had a very painful and infected tooth and they got me right in and took care of it. They were professional and listened extremely well. The root canal and follow up were painless. I highly recommend Dr Orrick and his practice.

The staff were very polite and professional getting me scheduled in around my difficult schedule. Dr. Orrick had the best chair side manners and did a spectacular job keeping me at ease through the procedure. The entire process was as pleasurable as a trip to the dentist can get! I will definitely be recommending Dr. Orrick and Gateway Endodontics to friends, family, and clients!

The office is great. Dr. Orrick is amazing. He has done a few procedures for me and every experience was great. They are compassionate and caring. I really liked how he explains what he's doing and how it will feel before he does the next step. They really care about my comfort as a patient, too. I would highly recommend using Gateway Endodontics for any procedure you need.

I recently had my first root canal experience with Doctor Orrick at the age of 63, and it was outstanding. Throughout the procedure, he thoroughly explained every step and detail, which greatly helped alleviate my anxiety. Although the procedure took a bit longer than expected, it was pain-free, with only minor discomfort during the numbing process, which was minimized by Dr. Orrick's specialized technique. I'm extremely satisfied with my experience and highly recommend Dr. Orrick to anyone requiring this type of care.

Dr. Orrick does excellent work. He takes the time to explain each process and during the procedure he was gentle and made sure I was comfortable at all times.

I am so shocked at how easy the root canal with Dr. Orrick was. I never had a root canal before, and I'm 40. He has his technique and art down - does it quick, gets you out quick, the process is mostly painless, even the recovery was painless for me. His anesthesia administration was also on point - he got it right the first time. Anytime I've had to get local anesthesia for anything anywhere else, the healthcare provider would have to try several times before I was numb. He was also super transparent about the process; there's a TV screen in front of you where he projects your x-rays and he explains the issue and what he's going to do to treat it. It's nice to know what's happening. As someone who always wants to know "why," I really liked that. Also, the woman at the desk is phenomenal (she's the same one who answers the phones). Her customer service skills, sharpness, and overall clarity and helpfulness is remarkable. She remembers details about you that surprised me (like which medications I'm allergic to, the fact I called her earlier in the week and she kept me in mind - and was able to get me in earlier two days later).

Doctor Orrick was most pleasant and professional throughout the whole process of my root canal. He explained the procedure carefully and I felt at ease with him. I definitely recommend him to anyone who needs to have this done. He’s very gentle and understanding.

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!
