Dr. Alcazar’s Biography

Dr. Alcazar was inspired to follow in the footsteps of his father, who was a well-respected dentist in the community. This led him to earn his dental degree and Certificate in Advance Graduate Studies in Orthodontics in Peru and in the Unites States respectively. Over time, he continued to hear great things about Willamette Dental from colleagues and knew the practice aligned perfectly with his own professional principles. Having always been driven to help others, he’s never shied away from a challenging case and feels a great sense of pride when his peers look to him for advice.

When not creating beautiful smiles, Dr. Alcazar loves to get out on the tennis court or reenergize in nature.

The whole Beaverton Team is amazing, from check-in to check-out. Dr. Alcazar and his assistant, Hailey, took time to answer all our questions and made the visit comfortable. This is our first experience with braces and the team was very knowledgeable and helped set my mind at ease.

The assistant I had was particularly exceptional. She was the most attentive staff I've had there, and that's saying a lot because everyone is generally really great. She just went above and beyond in my opinion. The doctor was awesome as usual too

Dental assistant was fantastic! Connected personally with us, gave excellent information, so kind and thorough. . . We've met Dr. Alcazar 3 times now, seems to do a good job, but not very personable, seems checked out/uninterested.

Both of my teenagers see him and he's great, never lectures but is firm. Explains in depth about what needs to be done if they want the results. Staff is always eager to greet us and check us in, In a timely manner. Thank you to everyone

Dr. Alcazar has made this entire process a breeze. Can't say enough good about him and his team.

The assistants do not know how to communicate with adults and anyone that doesn't do their job. I find their demeanor and customer care incredibly poor, unwelcoming, demeaning and glib. My entire visit should have gone differently if they had asked some questions, taken a look at my mouth and done a simple test. Now I am going to be set back further and waste more money.

The receptionist was a bit snarky.

I wish there was more discussion about the cavities that had formed on my son's teeth. The dentist didn't ask how he was brushing his teeth and didn't offer to show him the correct way to brush. There was also no communication about the developing cavities from his orthodontist who he sees about every six weeks. Very disappointing.

We're very satisfied with the service at Willamette Dental. From the time we walk into the office to the time of the appointment to the time we get to leave, everything's very, very well done. Everybody's very professional, very patient, and the communication is great, and I would highly recommend it with everybody. Thank you.

I really appreciate the relationship I have been with Dr. Alcazar over the past few years of Invisalign treatment and, most recently, completion of upper jaw surgery. His honesty and transparency has helped me to improve my own behaviors when it comes to taking care of my oral health and to ensure I am receiving the care I need. Every dental assistant is always friendly and supportive of my needs, especially when it comes to my teeth sensitivity or discomfort. I appreciate how they always make me feel comfortable and take time to connect with me through the appointment.

My son and I had a good experience with willamette dental. When we need to contact with them, they responded us very quickly. They explained us the details of my son's teeth and I comfortably relay on their professionalism. I definitely recommend willamette drntal to other people.

We generally really enjoy - yes, enjoy -our visits to the orthodontist, but this last visit was exceptionally good. We were late for our appt, the team was short staffed, and it was truly dreary outside and YET...they made time for us, they were friendly, they were professional and it was as pleasant an experience as always. The whole team connects with my daughter and makes sure she's comfortable. They make sure I know what's next and are happy repeat or demonstrate if I need it.

Great ortho experience. Everyone on the team did a great job at helping my daughter go through a rough time of getting braces and making it seem not so bad, everyone was very friendly, knowledgeable and put us both at ease knowing we were well taken care of. Thank you
