Meet the Team
Bonnie Graff, R.D.H.


Dental Hygienist Bonnie says her priority is to work in tandem with the rest of the dental team to provide full oral health care. Her training lets her specialize in the treatment and prevention of oral diseases such as Periodontal Disease and Dental Decay. She evaluates potential risk factors for these diseases by taking a full medical history, and performing an Oral Cancer Exam, a dentition exam, and a periodontal exam, and follows up with treatment which can include removal of plaque, calculus, and biofilm, as well as any necessary radiographs, fluoride treatments, and sealants.

Bonnie grew up in Richmond, Illinois until the age of 15, and has resided in the Woodstock area ever since. In 1988, she obtained her Associates in Applied Science from Harper College in Palatine, Illinois, and also holds Local Anesthesia Certification and Diode Laser Certification. She maintains 36 hours of continuing education every 3 years for licensure. Originally an oral surgery assistant, Bonnie realized she had a very real desire to learn more about other forms of Dentistry, and decided to turn her attention more towards the prevention of oral diseases.

When she isn't keeping patient's mouths healthy and shining, Bonnie is spending time with her husband, Derek, and the couple's three children, Grace, Gretchen, and Griffin. She enjoys coffee on the porch, swimming and boating on the lake, and hanging out at any ice rink or volleyball court her kids are on. She also supports Operation Christmas Child and Girls on the Run, charities that two of her friends work for.



For Dental Hygienist Deb, prevention is the name of the game. She assesses the oral health of patients and assists the doctors in evaluating and diagnosing periodontal disease. She helps patients maintain good oral health and prevent dental disease by preforming periodontal therapy including oral cancer exams, periodontal charting and detailed cleanings. She also takes radiographs, places dental sealants, and performs fluoride treatments.

Deb grew up in Palatine and has lived in Cary for over 25 years. She obtained her Associates in Applied Science of Dental Hygiene from Harper College in Palatine, Illinois, and also holds a Local Anesthesia certification. Deb completes a minimum of 36 hours Continuing Education hours every 3 years for maintaining her license. "I was able to have on the job training as a Dental Assistant directly after high school while attending Harper College," she remembers. "I enjoyed the dental profession and especially loved working with individual patients. The best part of my job is the one on one contact I have with my patients!"

When she's not brightening smiles and battling periodontal disease, Deb is spending time with friends, family. She has been married for over 30 years and has three daughters, one son-in-law and two grandchildren. Deb volunteers at her church with the P.A.D.S. program; a non-profit organization dedicated to providing emergency shelter, supportive housing and comprehensive resources to the homeless in McHenry County. She says she would love to go to visit Italy with her family.



Dental Assistant Marisa focuses on her job as an assistant to Dr. Brewer, helping patient's achieve brighter smiles and keeping their mouths healthy with sealants and polishing. "I love to smile, and I love helping my patients feel confident in their own smiles," she says.

Marisa is a native of Algonquin, and still lives there. She has 8 years of experience, and holds a Certificate for dental assisting as well as being certified for sealants and coronal polishing. "I've always enjoyed going to the dentist," she says, remembering asking her mom every month "Are we going to the dentist this month?" "I never had any cavities, and I loved having my teeth cleaned."

When she isn't assisting with dental procedures, Marisa is planning her upcoming wedding to fiancé Kevin, with whom she'll be tying the knot next year, working in the local animal shelter, boating, or simply spending time outside in the sun with her almost 1-year old son, Brayden. "I love spending time with friends and family, and would enjoy getting to travel with them if I had a year to spend dong anything!"



Practice office manager Penny says that the most important thing about dental health that people forget is how connected it is to overall health. "My childhood dentist actually smoked his pipe while he worked on us," she remembers, laughing. "I'm glad dentistry has come such a long way since then.

Born in Chicago, Penny and her family moved to West Dundee when she was 2 years old. She taught early education but became fascinated by orthodontics when her son required braces. "I asked so many questions at every appointment and was so involved that eventually the dentist's office offered me a job - and the rest is history!" she says. The holder of an Associate's degree, Penny stays on top of the dental profession with continuing education courses taken yearly.

When she's not helping the practice run smoothly, Penny is spending time with her family, which includes three shelter animals she and her husband have adopted over the years. She likes to golf in the summer, go snowmobiling in the winter, and read - particularly books about history. Penny dreams of taking a long vacation in Ireland with her family.



Tracy is the practice's part time receptionist and dental assistant. She helps cover most of the front desk responsibilities, scheduling appointments, checking patients in and out, updating the practice's electronic sign, and running errands.

Tracy spent most of her life in Crystal Lake and now resides in Prairie Grove. At the age of 18, Tracy took a job with a local dentist who was looking for an assistant. After some years off to raise her son, Tracy just recently came back to the industry when she joined husband Dr. Thomas Skleba's practice. "It's great being part of the family business," she says. "The staff here is wonderful. We have the best patients and I love meeting so many people."

When she's not helping out at the practice, Tracy is enjoying time at home with Thomas and the couple's teenaged son, Nick. "Our family is very close and we enjoy spending our downtime together."
