Dr. Baum

Frank R. Baum, MD 

obtained his undergraduate degree from Northwestern University in 1977 with departmental honors in Biological Science and his MD from the Chicago Medical School in 1981. He completed his pediatric residency at the Children's Hospital of Los Angeles in 1984 and was the recipient of the Della M. Mudd Award for the effective application of scientific knowledge, perceptiveness in the care of children and distinguished qualities of character.

From 1984 to 1985 Dr. Baum was a pediatric emergency room doctor at Children's Hospital of Los Angeles prior to moving to Maui. Dr. Baum wanted to be a pediatrician since he was 8 years old and feels that he has been living the dream ever since. His goal in practicing pediatrics has always been to make an impact on the health care of children in a small community.

When Dr. Baum is not in the office he can be found teaching Bricks 4 Kidz Maui STEM enrichment classes in many of Maui's elementary schools. In 2016 the Maui High School Foundation awarded Dr. Baum and his wife, Colleen F. Inouye, MD (gynecologist) the Saber Spirit Award. This award is given to an individual who is an unsung hero to the school. They are active supporters of HOSA - Future Health Professionals Organization at Maui High School and have funded the Maui High School Valedictorian Scholarship since 2003. Their adult son is a 2003 graduate of Maui High School and is pursuing his passion as a music video producer and director in Los Angeles. 

Dr. Baum

Leesa Foree, PA-C 

was born and raised on Maui and has aspired to be a pediatric provider since elementary school. She was a patient of Dr. Baum’s from the day she was born until the age of 18 and credits him as her greatest inspiration for pursuing a career in pediatric medicine. She graduated from Kamehameha Schools Maui in 2010 and went on to earn her undergraduate degree in Biology with a minor in Chemistry from Willamette University in 2014. 

Steadfast on the path to becoming a Physician Assistant, Leesa returned home to complete prerequisite courses at the University of Hawaii Maui College.  She also worked as a medical assistant at Frank R. Baum, M.D., Inc. and later in the pediatric department at the Maui Medical Group for a total of five years.  In August of 2021 Leesa graduated with her Master’s degree in Physician Assistant Studies from the Oregon Health & Sciences University School of Medicine Physician Assistant Program.

Leesa is the recipient of the Native Hawaiian Scholarship funded by the United States Department of Health’s Health Resources and Services Administration. This scholarship is awarded to Native Hawaiians dedicated to medically serving the unique health needs of the Native Hawaiian community.  Leesa is happy to be home and is excited to fulfill her life-long dream and passion for serving the keiki of Maui and their families.

Leesa’s favorite pastimes are dancing with the Maui Academy of Performing Arts (MAPA) and playing cello in the Kamehameha School’s orchestra.  She occasionally volunteers with the Maui Youth Philharmonic Orchestra which allows Maui’s youth the opportunity to learn and hone their ability to play musical instruments and gives them the experience of playing in a philharmonic orchestra.

Leanne Binas, Medical Assistant
was born and raised on Maui. She was a patient of Dr. Baum’s since she was born until she left for college. She graduated from H.P. Baldwin High School in 2019 and earned her Bachelor of Science degree in Biochemistry with a minor in Psychology from Seattle Pacific University in 2023. Leanne remembers growing up that Dr. Baum would always ask “What do you want to be when you grow up?” Each year, she would have a different answer but has finally settled on becoming a Physician Assistant.

Leanne is the youngest of 4 siblings whom were also previous patients of Dr. Baum. Now, she has 5 nieces and nephews that are all patients of Dr. Baum and Leesa. Her experience caring for them has made her feel right at home in the office. She previously worked at CVS Pharmacy where she worked as a pharmacy technician which deepened her interest in medicine. She hopes to continue serving the Maui community after attending school.

Leanne enjoys trying new foods, reading books, and listening to music. One of her favorite places to eat is at HI Thai food truck in Wailuku. Her current favorite artists are Taylor Swift and Sabrina Carpenter and even got to see them in concert. She is always open to trying new things and often tries to learn a new skill such as painting or cooking a new recipe.  

Alexis Gonsalves, Medical Assistant
grew up in Upcountry Maui. Alexis graduated from Kamehameha Schools Maui in 2019 and went on to earn a Bachelor of Science in Public Health with a minor in Biology from Pacific University in 2023. As a former patient of Dr. Baum, she has returned to work as a medical assistant for the practice in hopes of becoming a Physician Assistant in the near future.

There are many experiences that have shaped Alexis’s dedication to pediatric care that have inspired her to pursue a career in the medical field. The most influential is her being the youngest of 7 children where she learned to nurture and care for others. She hopes that in continuing this work for her community, she is able to uplift younger generations.

Alexis spends much of her free time supporting her nieces and nephews at sporting events and their various activities. She enjoys watching her favorite tv shows including the Rookie, the 100, and the Originals or reading books. Some of her favorite foods include sushi, dry mein, and beef stew. From a young age, Alexis has enjoyed traveling including trips abroad to Canada and Japan. She hopes to continue traveling to cross off destinations from her bucket list such as Indonesia, Portugal, and Italy.
