TMJ Treatment:  You are not alone.  Your first step is to call Dr. Andy, your TMJ/TMD dentist in Vancouver, WA today for an examination at our Cascade Dental, Fisher’s Landing office.

TMJ pain should not be ignored as it will not go away by itself.

Get To Know Dr. Andy

We recently asked Dr. Andy a few questions about his dentistry career.  Here are his answers. We thought you’d find it interesting!

How old were you, and what made you decide you wanted to become a dentist?
“I had a great role model as a dentist when growing up.  He was a family friend, a great guy, and a great dentist.  I made my mind up at age 7.”

What is one thing you find most satisfying about being a dentist?
“I enjoy building relationships with my patients in a mutually trusting environment.  When everyone works together, great things can be accomplished.”

What advice would you give to a young person considering a career in Dentistry?
“I would have them hit the sciences hard in school.  Science is a window to reality and is deeply fascinating.  You don’t have to be a nerd to appreciate the natural beauty quantified in science.  Besides that, observe several dentists in their practice.  Dentists are fine people.  Find a mentor whose practice you respect and admire and build around that.”

Why did you choose Cascade Dental ?
“I enjoy sorting out complex problems involving the jaw joint (TMJ), correcting bites (occlusion) and arriving at finished results that takes years off a patient’s appearance (esthetics).  The dentists and hygienists at Fisher’s Landing are all uncompromising in their service to patients.  The advanced training skills I have to offer are seen as important in their eyes, and they don’t hesitate to have their patients see if they feel I can improve their quality of life.  Also, I’m a positive person, and this is an office full of great attitudes!”

We hope you’ve enjoyed getting to know Dr. Andy better!  And, as always, THANKS for being our valued patients and friends!

Get to Know Dr. Dan:

How old were you, and what made you decide you wanted to become a dentist?
I was in college when I finally made the decision to pursue a career in dentistry.  A good friend and local pediatric dentist, Dr. Peter Lubisich III was a father figure and mentor to me.   His passion for the profession and the passion of his colleagues in his building helped inform me about dentistry and allow me to see this challenging field as a great opportunity to challenge myself and help patients by providing excellent care.

What advice would you give to a young person considering a career in Dentistry?
I have had the privilege of watching 3 patients choose a field in dentistry.  I have also been fortunate enough to share my passion with high school students or college students interested in learning about dentistry.  For all of them, I encourage them to learn as much about what we do on a daily basis with different doctors that are excited about their profession.   I encourage them to find a career that get them excited to grow and learn.  I am lucky to love what I do each day, and love that in the process I am able to help patients.

What is one thing you find most satisfying about being a dentist?
I love changing a patient’s outlook about the dentist.  All too often, we hear the words, “I’m sure you are a nice guy, but I hate the dentist”.  It may not happen overnight, but I love seeing those patients that wouldn’t come in for years, look forward to their next visits because of the trust they have in the care we provide for them.

Why did you choose Cascade Dental?
I have been a dentist in Clark County since 2002, and have watched Cascade Dental grow because of their great reputation and vision to serve the community to the best of their ability.  It is great to have the opportunity to discuss complicated cases with great doctors, and also have a great team supporting our goal of providing wonderful dental care to our patients.
