Office StaffArlington Heights, IL Dentist


Samantha Thelin – Registered Dental Hygienist

I was born in Arlington Heights and graduated Dental Hygiene school from Harper College. I am very passionate about my dental career. My interest in dentistry began as a teenager when I had my braces removed and I was fascinated by the substantial positive improvements dentistry is able to provide in the right hands. In the years that followed, I realized that the link between oral health and systemic health is substantial and I wanted to be a part of this as a career. I am very excited to bring my enthusiasm for quality, personalized dental care to each and every patient. I enjoy running, watching sports (love the Cubs), and I enjoy reading fiction novels and travel. Some of my favorite places I’ve visited include Australia, New Zealand, and Ireland—I enjoy talking to patients about their travel experiences and look forward to providing you with outstanding care and attention!


Jami McGee – Registered Dental Hygienist

Jami Registered Dental Hygienist in Arlington Heights IL

I graduated Dental Hygiene school from Harper College and I am very passionate about my dental career. My interest in dentistry began in a dental office near my hometown of St. Charles. In the years that followed, I gained experience in all areas of dental practice including front desk, dental assisting, and of course I became a Registered Dental Hygienist. I am very excited to bring my enthusiasm for quality, personalized dental care to each and every patient. I enjoy running, especially with Max, my German Shepherd and I love reading mystery novels and of course hanging out with family and friends. I spend a lot of my free time relaxing and enjoying Forest Lake.


Pam White – Registered Dental Hygienist

Pam Registered Dental Hygienist at AH Smiles

I was raised in Park Ridge and went on to the University of Iowa where I graduated in 1989 with a Bachelor of Science in Liberal Arts and major in Dental Hygiene. I am lucky to have made this practice my dental home for most of my career. Not only do I enjoy providing excellent care to each of my patients, I truly cherish the relationships that we have cultivated together. Giving back is important to me, so on my Fridays off I help run a food pantry that services those in need in the community. I reside in Crystal Lake with my husband and two wonderful children.


Sabina Klos – Registered Dental Hygienist

Sabina Registered Dental Hygienist at AH Smiles

Sabina was born in Poland and her college education was in Psychology. However, after moving to Chicago with her husband, Sabina immediately began working in dental practices. She has worked in nearly all areas of dentistry but has always been a fastidious person and knew dental hygiene, specifically, was the perfect career for her. A lover of art, she is a member of the Chicago Art Museum and particularly appreciates works by Vincent van Gogh. Even though red wine can stain the teeth, food and wine are among her passions. In her free time, Sabina enjoys skiing, biking, walking, and travel. Family is important to Sabina, and her two boys Niko and Jacob make life even more fun in Rolling Meadows where her family currently resides.


Maureen Cecilio – Office Coordinator

I was born in the north side of Chicago, and my management career started in retail as a General Manager.  After over a decade of retail management, I took the plunge to work for a dentist in Evanston who was opening her very own practice.  Being part of a brand new practice, I was able to learn the intricacies of a dental practice, both administrative and clinical.  It was a perfect marriage of my previous management experience and my belief in the importance of optimal oral health!  Supporting patients is my passion, and I look forward to  being a positive part of your dental experience in our practice.  Outside of work, I love spending  time with my husband and our kids which includes a son going to college in California, a daughter  going to college in Colorado, and a teenage son. When I’m not with my family, I love doing hot  yoga, strength training and bootcamp exercises, and anything that keeps me moving and physically  healthy.  


Jan Christman – Treatment Coordinator

I actually started with Dr. Uhler in 1979 and was trained to be a dental assistant, but since 2001 I have been a part of the front desk team for Dr. Engelberg. My husband Jim and I celebrated our 50 year wedding anniversary in August of 2016. We have three daughters, two son-in-laws, and four wonderful grandchildren. Jim and I are sport and activity enthusiasts for all of our terrific grandchildren. I enjoy working with all of our patients and of course cherish the relationships that have been built here for so many years. When I am not at the office I enjoy reading mystery novels and gardening. In fact, I make my own fresh salsa yearly from my garden.


Nancy Walker – Patient Reception Coordinator

I joined Dr. Engelberg’s team in 2017 and enjoy welcoming patients to the practice, coordinating appointments, and helping patients feel comfortable and at home in our excellent dental office. I believe dental care is important for everyone’s overall health, therefore I truly enjoy seeing individuals and families maintain optimum oral health and of course relish sharing in the excitement patients have once they’ve received their beautiful smiles! My husband and I enjoy the outdoors—we are routinely biking, walking, and we also love to travel. We enjoy the company of our three children and five grandchildren who range from preschool age through college. We are fortunate our family lives nearby and we strive to always be involved and have a meaningful and positive impact on their lives.


Roxana Urbina-Rivas – Dental Assistant

Dental Assistant at AH Smiles in Arlington Heights IL

I was born in the country of Peru and moved to Chicago in 1993. I was raised in Melrose Park and currently reside in Wood Dale. Many patients find it helpful that I speak fluent Spanish. I have been a dental assistant since 1998 and joined Dr. Engelberg’s team in 2013. I enjoy helping patients obtain healthy mouths and beautiful smiles. I love spending time with my husband and our two children, and we were married in 2015. I am very close with my family who live nearby. I love animals and have three cocker spaniels: Lola, Hanzel, and Lady.


Gosia Barczak – Dental Assistant

Gosia Dental Assistant at AH Smiles

I have been a dental assistant for over 15 years. I am so happy you have found us for many reasons, but mainly because in our office we provide very high quality dentistry from fillings, making crowns in the office in one day, to making beautiful veneers. I have been working for Dr. Engelberg since 2007 and through the years I’ve realized how much great dentistry can improve your overall oral health, and at the same time can change your life forever! Dentistry is not the only passion I have. A few years ago I became a certified Esthetician. Although these fields are different, they both make people happy to smile with great results. You might ask if this girl has any free time, yes I do! I love to cook, enjoy yoga, experiencing new restaurants, and spending time with my family and friends.
