About Us
Our mission is to eradicate canine cancer, improve the quality of life for canine patients, and give new hope to pet parents.

What We Do
Currently, cancer care for dogs lags behind human cancer care by about 20 years. But, from a biological and molecular standpoint, canine cancer is not so different from human cancer. FidoCure uses genomic testing to deduce what therapies may be most effective to treat your dog’s specific type of cancer. From there, precision medicine can be prescribed by your vet and administered in the comfort of your home.
Our goal is to improve the outcome for canine cancer patients. We are the first and only company to offer the information needed to work with your veterinarian on targeted medicines for dogs with cancer.
Our Story


Behind the founding of the One Health Company, the world’s first canine cancer care organization, are two very human stories, both rooted in cancer…
Ben Lewis is no stranger to the world of clinical trials. As a former Olympic team kayaker, he had access to cutting-edge experimental care focused on treating serious injuries. When his dog was diagnosed with cancer, the chance to enroll in a clinical trial for canine cancer treatment arose. Lewis seized the opportunity and his dog outlived his prognosis, cancer-free.
Christina Lopes, on the other hand, served as a caretaker for her father when he was diagnosed with terminal lung cancer. Her experience navigating this complex illness, combined with Lewis’ journey through clinical testing, provided the perfect platform on which to build One Health.
Together, they co-founded the One Health Company to offer cutting edge diagnostics and access to targeted therapies for dogs. “One Health” is a term vets use to refer to the integrative efforts of multiple disciplines working to attain optimal health for people and animals.
Our Medical & Veterinary Advisors
We have assembled a board of medical and veterinary advisors including multidisciplinary thinkers in the areas of canine and human oncology. They boldly use all of our resources to positively impact the outcome for dogs with cancer. Our vets have treated thousands of dogs over the past 30 years and work closely with our growing network of forward-thinking veterinarians throughout the US.

How dogs are teaching researchers new tricks for treating cancer by Sarah DeWeerdt, Nature
How Are Dogs Helping Us Cure Cancer in People? by Elaine K. Howley, U.S. News

Nicola Mason B.Vet.Med, PhD, ACVIM (SAIM)
Professor of Medicine & Pathobiology The Paul A. James and Charles A. Gilmore Endowed Chair Professorship within the Department of Clinical Sciences and Advanced Medicine, University of Pennsylvania School of Veterinary Medicine
Dr. Mason’s lab focuses on developing novel approaches to generate functional, tumor-specific cytotoxic T lymphocytes. One approach involves active immunization using whole tumor RNA loaded CD40 activated B cells, aimed at activating tumor specific T cells in vivo. A second approach involves the passive adoptive transfer of genetically modified autologous T cells that are capable of MHC-independent tumor antigen recognition and activation/effector function in the absence of co-stimulatory ligands.
A second related focus of Dr. Mason’s lab is to identify novel tumor-associated antigens and to develop single-chain Fragment variable targeting systems that can be used alone or in concert with cell based therapies to target spontaneous occurring tumors. Through innovative clinical trials in canine cancer patients, the lab is working in concert with clinical oncologists to evaluate the safety and efficacy of both active immunization and passive adoptive transfer of genetically modified T cells in the treatment of spontaneously occurring cancer.

Dr. Michelle White
DVM · PhD Head of Science
Dr. Michelle White joined FidoCure in 2022 as the Head of Science. She is particularly driven by excitement and urgency to use precision medicine to help dogs and humans. Ultimately, Dr. White is most passionate about treating each patient as an individual, using emerging technologies and insights to improve the lives of the animals and people we love.
During her freshman year at Harvard University, Michelle became enamored with genetics. She was fortunate to be accepted into the lab of Daniel Hartl PhD., where she focused on the interface between evolutionary biology and genomics. After graduating from Harvard, she spent several years as an internal consultant and retail analyst for retail companies in New York City. Michelle was later accepted to Cornell where she received first her DVM and later, a PhD in Translational Medicine working in the lab of Adam Boyko.
In 2020, Michelle joined Dr. Elinor Karlsson’s laboratory as a Senior Research Scientist at the University of Massachusetts Chan Medical School and the Broad Institute of MIT and Harvard. During her tenure there she collaborated with two FidoCure scientific advisory board members, Dr. Cheryl London and Dr. Corrie Painter.

She loves home automation, fermenting foods, and speaks mainly in references from The Simpsons.

Lucas Rodrigues
DVM, MS, PhD Head of Veterinary Research
Dr. Lucas Rodrigues is a veterinarian at FidoCure® investigating the impact of DNA mutations on tumor behavior, evaluating treatment possibilities based on genomic profile, and performing scientific research for conferences and manuscript publications. He is an experienced investigator with deep knowledge in clinical oncology and molecular biology and 15 years of experience in comparative oncology.
Dr. Rodrigues received his Doctor of Veterinary Medicine from the University Paulista in São Paulo, Brazil. After that, he completed his Master and Ph.D. degree at the Universidade of São Paulo. He has significant experience in molecular biology, which was acquired during his 5 years of postdoctoral research at University of Wisconsin-Madison and Penn State University. He worked in several projects funded by The National Cancer Institute (NCI) and other agencies and has authored over 10 peer-reviewed journal papers and four book chapters.
During his postdoc work Dr. Rodrigues was the first to identify the expression of FZD-6 in osteosarcoma and suggest that the increased expression suppresses the Wnt/β-catenin signaling pathway, which in turn prevents the differentiation of cells and contributes to osteosarcoma tumor-initiating cells. While at Penn State University, he prepared the first study to report the critical role of IGF2BP1 in melanoma metastasis, in addition to being the first study to demonstrate the role of any RNA-binding protein in the extracellular vesicle-mediated promotion of metastasis.
Dr. Rodrigues is continuing his work in the field of cancer research developing personalized medicine for dogs with cancer through the use of cutting-edge technologies and taking the advantage of comparative oncology to also benefit human treatment against this devastating disease.
