Monica grew up in Glendora CA and is the eldest of four children. She has two very mischievous dogs named “Oreo” and “Ivory” and enjoys hiking, reading, playing the clarinet, attending church and spending time with family and friends.
Monica began working in the field of Dermatology in her senior year of High School and soon learned many aspects of the specialty that she has been able to apply to her daily life.
“I was fortunate enough to understand how important the skin is at a young age. After seeing how prominent skin cancer is, I was the one telling my friends and family not to tan and to use sunscreens. I know it’s difficult living in sunny California but I feel the skin is something we all kind of leave for last- once the damage is done.”
Along with Jessica and Denise, Monica was a founding member of the Foothill Dermatology Medical Center and has been with Dr. Sidhu since day one.
“It has been a difficult yet rewarding experience. I think one of the best things, is being able to see the healing process take place in the different patient cases we see. Although I am not the one treating the patient, it is always wonderful to see the improvement people make. And there is nothing better than to get to know the individuals that walk through the door on a personal level. Hearing their fun family stories, seeing pictures from their trips, and being able to be a listening ear and shoulder during the bad times as well – which can go both ways.”
