Clinical Team Leads
I've dedicated the past 18 years to working with our patients here at Zak Dental. My experience extends from managing our amazing and talented front staff team, but also our incredible clinical staff. I am clinically trained as a Registered Dental Assistant (RDA), having attending the Dental Professionals of California; so I have a true clinical understanding of your dental needs.
The most rewarding part of working in the field is in the satisfaction of helping our patients transform their smile into their DREAM smile! I will be here to help you every step of the way. When I'm not helping our patients smile, I enjoy spending time with my family and hiking.
My name is Ignacio Robles III, and I am the office manager for Dr. Zak Dental Care and Orthodontics in Santa Barbara. Originally from Orange County, I have worked in the dental field for almost 20 years. Having served 5 years in the United States Marine Corps, I have traveled to many different parts of the world. I decided to get back into dentistry after completing two years of college in Long Beach, CA. I started as a sterilization technician at the age of 17; from the very first day, I have always enjoyed working in the dental field. I’ve been in the dental office almost my entire life! My mother also worked in dentistry and brought me for regular visits to her office as a child. Being around dentistry became second nature, so it only made sense that I pursue this as a career. I have a family of 12, including my two boys, my daughter, five stepdaughters and three grand kids. I enjoy long walks at the beach and practicing my military training casually at the shooting range. I am looking forward to meeting you and helping with all your dental needs at the Santa Barbara office!
My name is Shirley and I have spent the past 24 years serving others in the dental field. I love people and enjoy working with others. I have hands on experience with patients in both the back office as a dental assistant, as well as all aspects of front office administration, including insurance billing and coordinating treatment. I enjoy helping others find the best way to move forward with the exceptional care they deserve. I have dedicated my efforts to making sure our patients receive quality, personalized care and are comfortable at all times. I enjoy spending time with my grown children and grandchildren as often as possible, and of course we cannot forget our fur babies, who are also an essential part of our family and are involved in many outdoor family activities. I look forward to continuing my service to others!
The Zak Dental 360 Degree Quality Control Method:
We don’t just talk the talk…We walk the walk when it comes to Quality Assurance!!!
|1.||We have a Wellness Doctor on staff at every one of our locations. The sole purpose of this Doctor is to understand your unique oral health needs, objectives, and budget. Once your Wellness Doctor understands your needs, he creates a customized treatment plan that is unique to you. Based on the treatments needed, the Wellness Doctor will build a clinical team consisting of a hygienist, treating dentist, and possible specialists to execute the agreed upon family dental plans.|
|2.||There is always more than one provider working on your treatment plan to confirm the accuracy of your diagnosis.|
|3.||We practice a team-based approach to dental care because dental care requires a vast array of skills and abilities. In nearly thirty years of practice, Dr. Zak has never met a true “Master of All Trades” dentist. That is why we have paired up with a team of specialists that include: periodontists, endodontists, prosthodontists, oral surgeons, and orthodontists to support our general team and step in for more complex procedures.|
|4.||We have a 360-degree quality control protocol in place where at the end of your treatment your Wellness Doctor steps back in to check the quality of the completed work.|
