Meet Dr. Anjana Gupta

Dr. Anjana Gupta has wanted to be a dentist since she was 5 years old and feels incredibly lucky to share her profession and life with her amazing staff and loyal patients. Smiles on Niles is truly a dream come true, and she hopes her passion for dentistry is infectious. Dr. G joined the existing practice of Dr. Lisa McShane in June 2011 and became practice owner in 2017. Dr. G took complete ownership of the practice in 2020 (during a global pandemic!). She received her B.S. in biology at Indiana University (Go Hoosiers!) and earned her D.D.S. from Indiana University School of Dentistry in 2007. Dr. Gupta is a long-standing member of the American Dental Society, Michigan Dental Association, Indiana Dental Association, Chicago Dental Association, and local Lakeland Valley Dental Association. 

Dr. G was born and raised in Elkhart, Indiana. She resides here in St. Joe with her husband, Seth Brown, her daughter, Alice, and her son, Andre. Dr. G enjoys the beautiful Lake Michigan beaches in the summertime, playing tennis, pretending to be a foodie, traveling, and most of all, spending time with friends and family.


Registered Dental Hygienists

Coreen Clark, RDH

Coreen has worked with Dr. McShane since 2007 and Dr. Gupta since 2011. Coreen has been constant within the walls of 2800 Niles. Dr. Gupta says one of Coreen's best qualities is her ability to make people feel comfortable when coming to the dentist. "She puts them right at ease."

Coreen has lived in the area now for 20 years and has two children whom she adores. Coreen enjoys TJ Maxx shopping, hiking Grand Mere, and enjoying the local beauty and fun that St. Joe has to offer.

Kindra Mock, RDH

Kindra graduated from the Kalamazoo Valley Community College Dental Hygiene Program in 1996 and is certified in local anesthesia administration in the State of Michigan. Kindra has worked with Dr. McShane since 2000 and Dr. Gupta since 2011. Dr. Gupta says one of Kindra's best qualities is her ability to make people laugh. Kindra has a laugh that is contagious, and we all love hearing it throughout the day!

Kindra and her husband, Kevin, have two beautiful children. Kindra enjoys camping with her family in the summertime, going to concerts, and watching ND football. 


Dr. Soo Sim joined Dr. McShane and Dr. Gupta as a part-time associate dentist in March 2019.  She was born and raised in Northwest Indiana and attended Indiana University, where she received her degree in biology with a minor in chemistry.  Dr. Sim then attended Indiana University School of Dentistry and graduated alongside Dr. Gupta in 2007.  Dr. Sim and and Dr. Gupta have been best friends since meeting their very first day of dental school, and working together is a bit of a dream come true. She currently resides in Chicago and travels to St. Joe to practice. She enjoys trying different restaurants, running along the lake, and going to concerts. Dr. Sim enjoys spending her free time with her family and friends (especially Alice!) and she is very excited about bringing her passion for dentistry to St. Joe!


Leanie Staniszewski, RDH

Leanie graduated from the Dental Hygiene Program at Indiana University South Bend in 1994. She joined Dr. Gupta and her team in January 2023, bringing more than 20 years of experience as a dental hygienist. The team enjoys learning new things from Leanie’s experience, and she also contributes a calming presence to the office.  


Leanie lives in Berrien Center with her husband and three beautiful children. Outside of her role at Smiles on Niles, she enjoys traveling, being in nature, and gardening. 

Dental Assistants

Dental assistants work with and assist the dentist during clinical procedures. Our team of dental assistants include:

Corin graduated from the Lake Michigan College Dental Assisting Program in 2004.  Corin has worked with Dr. McShane since 2010 and Dr. Gupta since 2011. Corin is a registered dental assistant (RDA) and also a "jack of all trades." Corin has been Dr. Gupta's right-hand woman for years now. Corin's chair-side manner and knowledge of dentistry is second to none.

Corin grew up in Stevensville but considers Berrien Springs her hometown. She and her husband, Colin, have three incredible children. Corin stays busy with her kids' activities and loves every second of it. She enjoys sitting on her patio, going to the Mark III with her family, and spending quality time together.

Lindsay Ryno, RDA

Lindsay brings nearly 10 years of experience to Smiles on Niles as a dental assistant. After graduating from the Lake Michigan College Dental Assisting Program in 2014, she immediately began working for Dr. John Kim in oral surgery. Once Dr. Kim retired in September 2022, Lindsay joined the Smiles on Niles team. She couldn’t be happier and is excited to continue saving the smiles of our beautiful community.

The happy couple eagerly awaits the arrival of their firstborn, a baby girl, due in July 2023. When away from the office, Lindsay enjoys camping with her family and doing all things outdoors!
