Phoenix Office Team

Cruz

Front Desk and Treatment Coordinator

I love being one of the first people our patients meet when they come to our office. I coordinate appointments, maintain good customer relations, and communicate with patients about available treatment plans. The best part of working here is being involved with families’ orthodontic treatment. I love how thrilled and excited patients are about the process and progress they see. I also get to work with great friends and coworkers. Dr. Zinn, Raquel, Ariana, and the rest of the staff are very helpful, caring people who work together as a team.

Born and raised in Phoenix, AZ, I have lived in Maryvale my whole life. I like outdoors, traveling, hiking, and nature. I’m a Cowboys football fan and plan on visiting AT&T Stadium this year!

Ariana

Lead Back Office Assistant

I went to AIDA Camericah Institute for my dental assisting certification in 2013. I then started at an orthodontic office and have loved working in the specialty ever since! I joined Smile Straight Orthodontics in 2017, where I manage the back office, as well as provide the best patient care as possible. My favorite part of my job is not only meeting new faces and new smiles, but also meeting new challenges every day. I hope all our patients get excited for their journey with us.

When I’m not in the office, I am pursuing my dream to become a hygienist. I currently live in Arcadia with my best friend and my precious dog Dolce. I love to dance the night away to great music, as well as weight lift, box, and hike.

Selena

Sterilization Tech, Records, and Social Media Ambassador

I went to East Valley of Institute of technology for one year of anatomy and physiology and two years for dental schooling. Working at Smile Straight since 2018, my job entail taking pictures and X-rays of teeth, cleaning instruments, taking pictures of patients for our social media page, and creating content for social media. I love working with Dr. Zinn and my team because we are like family. We build each other, help each other, and learn from one another. If anyone is having a bad day, someone is always there to make that person smile and have a better day!

I’m a very open person, always trying to learn new things. I love being outdoors and just exploring nature, doing fun activities outside or inside. Family means everything to me!

Raquel

Office Manager

I began my career in 2007 working in general and pediatric dentistry, and have been at Smile Straight as an office manager since 2014. I manage office functions, coordinate the schedule, and consult with new patients. I love meeting all the new people who come in to learn about orthodontics; everyone is so different and interesting! Being a part of this team is a dream. Dr. Zinn is great at what she does and she’s always honest with patients. Our office is full of empathy and fun!

I love spending time with my two beautiful daughters and enjoy going up North in Arizona!


Tucson Office Team

Denise

Insurance / Financial Coordinator

I began my career in general dentistry in 1989 and in orthodontics in 1998. In 2007, my daughter sent my resume to Smile Straight Orthodontics and I’ve been working here ever since! I am responsible for all aspects of insurance, including verifications and billing. I also provide support to the office manager and other front office staff.

I love working for Dr. Bartchi, Dr. Seto, and the rest of our team because we really like each other and help to support each other daily. It makes it so much easier to come to work in an environment where everyone steps up to help each other out.

My husband Dave and I have been married for 30 years. We’ve raised four children and now have five grandchildren! We also have two dogs: Brown Dog and Buttercup. We enjoy spending time with our large family and watching baseball. My favorite “girl time” going to Disneyland with my daughters and their daughters.

Vanessa

Treatment Coordinator

I welcome new patients to our office and help explain the treatment plans generated by the doctor. Once a treatment plan is discussed, I present financial options for families. I love helping families that thought there was no way they could afford orthodontic treatment. I also love seeing patients’ results who come through our office and complete their treatment. Their life-changing smiles are great to see!

Both Dr. Bartschi and Dr. Seto are amazing doctors to work with. They are both very thorough in their work and have the patients’ best interest in mind. Our entire team is caring, customer service oriented, and passionate about what we do.

I have four children: two boys and two girls. We are very active in park sports, so I am always cheering from the sidelines!

Ileana

Orthodontic Assistant

Our doctors and the whole team at Smile Straight Orthodontics truly want the best results for patients and for everyone to enjoy having braces! I work in the clinic, where I assist the doctors during various procedures, including placing brackets, making adjustments, and removing braces. I love seeing patients excited to get started and celebrate the day they finish with a great smile! Watching people become more confident and outgoing keeps me loving my work.

Outside of the office, I love spending time with my boyfriend and our chocolate Lab.

Oscar

Orthodontic Assistant

I joined the Smile Straight team in 2017 to assist the doctors during various orthodontic procedures. I love seeing the process of orthodontic treatment and the way that our patients’ lives are changed. Working with the Smile Straight team is great. We get along very well and we have great teamwork.

I am a very active person, so in my free time, I like to go to the gym or play sports. My favorite sport is soccer and I am very passionate about it.

Argelia

Back Office Manager

My job is to assist Dr. Bartschi and Dr. Seto, hire new dental assistants and help them grow in their profession, and order back office supplies for all our Tucson locations. I love being a team player to change patients’ smiles and help them feel more confident! Our patients are wonderful people and I enjoy helping them achieve the wonderful smiles they deserve!

Originally from California, I love Arizona because I met amazing people and enjoy the beautiful weather. I am a proud mother of two boys who are my world.

Gabriela

Back Office Assistant

I am one of our assistants at Smile Straight Orthodontics, where I spend my days alongside Dr. Bartschi and Dr. Seto helping with orthodontic procedures. The most fulfilling aspect of my job is helping patients achieve a beautiful smile. I love being a part of such a great team with amazing doctors.

I was born and raised in the small border town of Douglas, AZ. My fiancé Jaime and baby Jade are my world. I love weekends because I get to spend them in Douglas or across the border in Sonora with all my family. Many mornings, I like waking up early to go hike Tumamoc Hill before getting to work.

Martin

Back Office Manager / Orthodontic Assistant

My goal is to make patients feel comfortable while doing adjustments, take records, and manage the back office for Dr. Seto’s team. I also greet new patients, take X-rays, and provide the office tour. My favorite part of my job is watching patients’ smiles after orthodontic treatment.

I have been in general dentistry and orthodontics for seven years and recently joined the Smile Straight team. Everyone here is hardworking and fun! It makes it very easy to wake up and love coming to work.

After work, I love watching and playing soccer and being outdoors.

Natalie

Office Manager

I do a little bit of everything to help our office run smoothly. Each day, you may find me running our morning office meetings, monitoring the schedule, tending to payroll, training new staff, marketing our office to the community, and assisting patients with appointment scheduling and insurance verifications. My favorite part of my job is watching patients grow and mature. I love to see how we change the lives of patients who are self-conscience of their smile and give them confidence to go out into the world.

I love working with my team because everyone is helpful, open to new ideas, and loves their job. We all respect each other and treat each other like family.

I am a mother of two children, Jake and Lily. I am engaged to an amazing man, Rolando Martinez, who is from San Diego, California. In our spare time, we watch movies and go around the town attending community events with our children. We love to spend our vacations or free time in California visiting family and going to Disneyland.

Natali

New Patient Coordinator

I have the pleasure of answering new patient calls and scheduling them for the best date and time. It’s so exciting to help new patients get the smile they have always wanted and make them feel comfortable in their own skin. Seeing their smile transformation is cool! Another thing I love about our office is our doctors. They are super awesome and welcoming and really care about their patients, which is awesome!

On my off days, I enjoy working out, traveling, and spending time with my boyfriend, friends, and family. I have a son, so spending as much time as I can with him is super important to me. My family and I are big on sports, so I really enjoy game nights!

Mercy

Front Desk/Treatment Coordinator

Greetings from the front desk! I’m one of the people who help patients as they check in for appointments, schedule appointments, present treatment estimates, and most importantly, am a part of creating happy, healthy smiles. My favorite part of my job is seeing how happy patients are after they have completed orthodontics and see their smile for the first time without braces.

I started as a dental assistant in general dentistry 12 years ago. Since then, I have had the privilege of working in many different dental fields including pediatric dentistry, periodontics, orthodontics, oral surgery, and front desk. In joining the Smile Straight team, I have become part of a group that has a fun and unique way of making our patients smile. My dental team rocks because we all get along great and have awesome team communication.

I am a single mother of two amazing children. My son Nickolas plays for the Tucson Redskins 13 YOU team. My daughter Esperanza plays softball and loves animals. Most of my evenings and weekends are busy juggling sports between both kids, but I would not have it any other way. In my free time, I enjoy going to country concerts, watching Braves baseball and U of A football/basketball games and tailgating, hiking, and riding dirt bikes and quads with my family.
