Maryellen Bonito, PA-C

Physician Assistant

Maryellen attended Wagner College in Staten Island, NY, for both her undergraduate degree and Master's of Physician Assistant Studies. She graduated in 2013 and then entered a one-year Post-Graduate Emergency Medicine Physician Assistant Residency Program at NewYork-Presbyterian / Weill Cornell Medicine. Upon completion, she stayed on board at Weill Cornell Medicine / Lower Manhattan Hospital and spent the first nine years of her career as an Emergency Medicine Physician Assistant.

After years of taking a very "traditional" approach to patient care, Maryellen found herself developing a growing interest in complementary and alternative medicine. She began working part time at Hyperbaric Medical Solutions in 2021, in hopes of formally exploring another side of healthcare. She quickly grew to love the new concepts and approach and transitioned to working at HMS full time shortly thereafter. She currently serves as the lead clinician for the NYC office. She has found this shift in her career to be eye opening, exciting, and genuinely fulfilling. 

Maryellen is proud to be a part of the regenerative medicine community and is thrilled to continually navigate this space as an HMS provider, where she has the opportunity to work alongside many well-respected and distinguished professionals. The HMS clinical group is comprised of individuals from various backgrounds who collectively offer an extensive level of expertise about hyperbarics, and beyond. Furthermore, everyone's dedication and enthusiasm have led to countless accomplishments and achievements over the years. Overall, she is honored to be a part of the impressive and inspiring team of clinicians at HMS.

Maryellen is looking forward to what is to come, in the world of regenerative medicine, and hyperbarics specifically. She is especially excited to be a part of this journey with HMS, as the organization continues to pave the path towards the future of this industry.
