Upland Dental Office Manager

My name is Magda Yacoub, I'm your friendly neighborhood Office Manager! I have various duties at the office, but my number one concern is the patient's overall experience and satisfaction. Outside of the office, I enjoy spending time with my family. My kids often tell me I'm too cordial and passionate. If you see me at the office during your visit, be sure to say hi!


Chino Dental Office Manager

My mother is an RDA so I practically grew up in the dental office. I followed in her footsteps and obtained my RDA license in 2014. Then I spent a few years expanding my knowledge, developing new skills, and evolving as a dental professional. I joined Barsoum Dental in 2018. It is a great honor to work with such an esteemed team of dental professionals that are truly dedicated to providing quality dental care and service. I embraced my new role as the Office Manager in 2021 and am grateful to have a career where I am able to exercise my passion for helping people surrounded by a team that feels like family. I spend most of my free time with my better half. I always have a coffee in hand and like cooking, hiking, and DIY projects. I love trying out Tik Tok recipes and finding new items at Trader Joe's.


Treatment Coordinator

I am a Treatment Coordinator at Barsoum Dental. I love working here because we have a great family dynamic, and I feel supported. I became interested in the dental field after taking a tour while my sister attended a vocational college. I was seeking a career and fell in love with dentistry. I began working at Barsoum Dental as an RDA but had to pivot into a front-office role due to an ankle injury. My ankle is better now, but you’ll still find me working in the front office because I found a passion for treatment coordinating, and explaining insurance benefits. In my free time, I like going to the gym and hanging out with family and friends. I have a sweet tooth for Raisinets and I love any song by Linkin Park.



I became a Registered Dental Assistant after high school because I liked helping people. I joined Barsoum Dental in 2007 and had the pleasure of watching and contributing to, our growing success. I love working here because the Dentists and Staff genuinely care about the patients. It is very rewarding to help patients achieve their dream smiles. I enjoy spending time with my kids, attending a women's bible study group, eating Mexican food, and listening to oldies.


Lead Treatment Coordinator

With over 20 plus years of being in the dental field, I have been blessed these past 6 years to be a part of Dr. Barsoum's team as a Coordinator for Oral Surgery, Orthodontics and General Dentistry services. I enjoy putting my patients at ease and offering reassurance and support during their dental experience. I want every patient to feel valued and heard. When I am not busy coordinating and ensuring exceptional patient care, I can often be found immersing myself in the great outdoors and spending time with family, my first granddaughter, and friends.



I am in charge of the accounts, and I am at your service anytime.



I was honored to join Barsoum Dental in 2012. I truly enjoy working with Dr. Barsoum and his team because I know I am working with fellow dental health care professionals that share my passion for providing only the best quality patient care. I am passionate about dental hygiene and I believe good oral health is an essential component in overall all health. I am a proud member of several professional organizations including The Tri-County Dental Hygiene Society and The American Dental Hygiene Association. I consider myself a lifelong learner and attend several continuing education courses a year. I enjoy traveling and trying new foods, but most of all I love spending time with my husband and our two boys.

Dawn B


I have been a Registered Dental Hygienist for over 25 years and began working at Barsoum Dental in 2017. I have genuine compassion for my profession and strive to be sensitive to patients' needs. I provide personalized treatment with a caring and comfortable touch. I treasure the wonderful relationships I’ve built with my patients throughout my career. Out of the office, I enjoy camping and spending time with my husband, son, daughter, and grandchildren.


Registered Dental Assistant Extended Function

I am a Registered Dental Assistant in Extended Functions at Barsoum Dental. I stumbled into the dental field by accident, and I have come to love it. I started as a dental assistant, but my passion drove me to further my knowledge at UCLA. I graduated and obtained my RDAEF2 license, which is equivalent to a physician’s assistant in the medical field. I continue to work very closely with Loma Linda university and help train and guide new generations of RDAEF2. I love working here because of the team atmosphere and the family feel. My favorite color is red, and chips and salsa are definitely my favorite snack. I enjoy being outdoors with my family at the beach or swimming in the pool and cooking.


Specialty Manager

As Barsoum Dental's Specialty Coordinator, I help guests with their specialty care like Endodontics, Periodontics, Orthodontics, and Oral Surgery. I've been in the dental field for over 30 years now, and  I fell in love with the industry after putting myself through braces. Having straight teeth really built up my self-esteem, and I wasn’t afraid to smile anymore, which is why I enjoy helping others achieve their dream smile. I consider my coworkers my dental family. My husband and I have three grown sons and one teenage daughter. We enjoy spending time together, especially going on out-of-town adventures. I also love dancing, cooking, baking, and treating myself to mani/pedis. 



I graduated from Riverside College in 2012 with my degree in Dental Hygiene. I joined Dr.Barsoum's team in 2012. I am passionate about helping people, educating patients about the importance of good oral health, and making sure the patients always have a comfortable and positive experience.



I have been a dental hygienist for 11 years and started working with Dr. Barsoum in 2013. Throughout my education, I realized the importance of personalized care in oral hygiene. I firmly believe that each patient has unique needs, and it's my mission to help them find what works best for them.

What I love most about being a hygienist is the opportunity to build relationships with my patients, assisting them in achieving their individual oral health goals. I'm deeply committed to providing the highest quality of care, ensuring that every patient who walks through our doors receives the attention and support they deserve.

It's incredibly fulfilling to make a positive impact in the lives of those I serve, and I'm grateful for the opportunity to continue doing so each day.


Oral Surgery Coordinator

I am Barsoum Dental's Oral Surgery Coordinator. I started working here just one day after I turned 18. Initially, I handled insurance verification and explanations. I slowly began helping out in all areas, and I realized how much I enjoyed specialty dentistry, specifically Oral Surgery.  My favorite color is pink, and I love to draw and go to concerts in my free time. I listen to all kinds of music, but I love BTS. I have a pitbull named Indiana Jones, which is also my favorite ride at Disneyland.  My guilty pleasures are Hot Cheetos, Raising Canes, and Sushi.

Hello everyone! My name is Hanh. I'm a RDAEF. I'm in the dental field for 11 years and joined Dr. Barsoum's team in 2011. I went to UCLA to continue my education and got my RDAEF license. My goal is not only to make people smile but also to make them feel comfortable and enjoy coming to our dental office. I like to cook all kinds of food, go shopping and spend time with my husband and my 14 years old son.


Front Office

I have been in the dental field for over 25 years. I just sort of fell into it and never looked back! I joined Barsoum Dental in 2017, and I am so happy and honored to be a part of Dr. Barsoum's dental family. I love that our primary focus is to provide excellent customer service and positive dental experiences to our patients. When I am not working, you might see me around rescuing stray cats, dogs, and even an emu once.  I enjoy spending time with my husband, going out to eat, and trying my luck out at the casino. I have family in Idaho and visit when I can.


Registered Dental Assistant

My journey began in 2018 as a dental assistant extern at Barsoum Dental. I immediately developed a passion for helping people and educating patients on their oral health care. So, it didn’t take long for me to join the team permanently and get my RDA license. I plan on continuing my education to become a dental hygienist in the future. In my free time, I like to be surrounded by my family and friends. I also enjoy traveling/camping, hiking and dancing. 


Treatment Plan Coordinator

At Barsoum Dental, I work as a Treatment Plan Coordinator. I got my start in the dental field at just 18 years old, helping with miscellaneous clerical work. Over time, I took on more responsibilities, and as I learned more about dentistry, I grew to love the industry. So, I went to school, got my RDA license, and worked my way up to my current position. I plan to continue growing in my career at Barsoum Dental. I enjoy eating In-N-Out and watching Grey's Anatomy.  I love going to Disneyland with my fiance, but most of my free time is spent on wedding planning. I also have a pug and a bunny that keep me very busy.
