Dr. Adjaj’s Biography

Dr. Adjaj was midway through medical school when he relocated to the United States, starting from scratch with few resources to his name. He was working full-time at a grocery store while attending Portland State University as a premed freshman when, on an off chance, he decided to join a lecture on dental school. He’s been hooked on dentistry ever since. What he enjoys most about dentistry is its ability to meld health care with hands-on practice.

Dr. Adjaj is outgoing and entertaining, always able to offer the perfect icebreaker. He enjoys a range of activities from jogging to travel to movies to PlayStation.

Dr. Adjaj was wonderful! He was so kind, explained things very well and gave me a great treatment plan for the issue I was having. The other staff were also friendly and made me feel at ease.

The staff were nice, but I think the building is in a bad location and the inside is very outdated. There was no color and felt very stark and uninviting. No Tv to watch while getting teeth cleaned and nitrous was not readily available unless specified beforehand. My experience was meh. I probably will go somewhere else next time.

Aug 24, 2025

Best group ever to work with!

Dr Adjaj is amazing. He treats conservatively before jumping to drastic measures and I appreciate that. I got an appointment right the next day and that was fantastic. I'm very impressed with the Mill Plain office in general.

For anxiety ridden patients, is not for to charge for laughing gas... I've spent most of my life knowing that I will have that to chill me out...but since be required to switch to willamete, now get charged. It's prevented me from being regular with appointments

Aug 9, 2025

5

I got lucky enough to get the appointment that I did, as the next available er appointment was almost a month out. Please have more ER appointments available as often things happen over the weekend and patients need to be seen rather than have to wait a few days or more for an appointment.

The hygienist forgot to polish the left upper quadrant of my teeth. As I was new to her, I wasn't comfortable saying anything.

Jun 15, 2025

The doctor at this clinic is very polite and professional in his field. I have been getting my teeth treated by this doctor for many years and I am always very pleased with the result!!! 10 out of 10 points!!!

The team got me in on short notice and all were extremely professional and courteous...

Jun 14, 2025

They were all awesome and also the dental technician was super kind to my gums. I have crowded teeth and others have just jammed the dental floss into my gums and made them bleed from the sheer force they had to use to get the floss through me teeth then blamed my lack of flossing for their own mistakes. This one didn't do that. She knew what she was doing and didn't traumatize my poor mouth. So at the. End of the appointment, my mouth felt clean and undamaged! Best appointment ever!!!

My dentist numbed me perfectly when he pulled my tooth. My tooth was stubborn and came out in 3 pieces. I ended up having pain before he removed the last root and he numbed me again in the area. He was patient, kind, and super funny. His assistant was so sweet and patient with me. They worked very well together.

Apr 28, 2025

I had a question about my crown, my dentist saw me for no longer than 7 minutes, it was obvious he was rushing through end of day patients, it felt like my concerns were not really addressed. He was basically like "oh, it's just this" and on to the next patient.

Apr 27, 2025

1

Your office is at a complete stand still and cannot handle the patient load it has. It is almost criminal to have the staff try and accommodate and keep all the patients happy. You have absolutely no business taking on new patients when you can't see the ones you already have.

Apr 27, 2025

2

Stop overbooking, provide timely appointments and there is too much hurrying doing meager service even after keeping us await for beyond supposed time

Apr 27, 2025

3

They didn't start treatment until 35 minutes past my appointment time. No one came to check in and communicate that there was a delay. I literally almost walked out as there was no communication at all. A cursory apology was made, but it did make me late to my next appointment

Apr 27, 2025

4

All the staff were really friendly and helpful with what I needed to get done.

Apr 28, 2025

5

She was very prompt. Very polite and a few inside jokes . I definitely recommend

Apr 27, 2025

3

It is extremely difficult to get an appointment, it takes months. A lot of times stuff they could do then and there they make you come back three to six months later which I don't like. They seem to push and push and push for having caps or crowns when it doesn't always seem necessary. I'm not really happy with the service. It has definitely gone downhill in the last few years.

Apr 27, 2025

5

Very friendly and attentive staff.

Apr 27, 2025

5

My experience was wonderful. I really liked the staff. They took really good care of me. I had been in an accident earlier the week before, and they made sure that my neck and my back were comfortable, and they really just provided me with everything that I needed. They got me into my appointment within the same day, and just really, really happy, and very happy that they are my dental network now. So yes, I will refer them, and yes, I will say great things at my company about them. So thank you so much.

Mar 2, 2025

I lost a filling, and I called to see if the office could fit me in. They gave me a "waiting appointment" the next day to come in and wait until a dentist had a moment to look at my issue. But it turned out they had a cancellation, so they could get me in for a regular appointment the next day. Great!

Feb 24, 2025

Keep up the good work

Feb 17, 2025

To be fit in on a snowy day and to actually find out what the problem is was a great relief. Thank you!

Feb 17, 2025
