I can’t say enough amazing things about Larimar Med. I’ve been working with Dr. Fitz since summer of 2024 and she’s truly helped me get my life back on track. With her guidance, I’ve lost around 60 pounds. By following her plan, which means doing all the things ( getting your steps in, lifting, watching what you’re eating) it works. I actually enjoy taking care of myself again. About a year and a half ago, Dr. Fitz also starting me on BHRT, and that has been absolutely life-changing. She is incredibly knowledgeable, takes the time to explain everything and truly looks at the whole picture of your health. Between the lifestyle changes, weight loss, BHRT, I honestly feel like I’ve aged backwards. I’m 56 years old and I feel like I’m back in my 30s. I feel fabulous. Heather has been amazing and is truly an artist at what she does. She did my lips first, and then I decided to do ultra clear to smoothing and tighten my skin on my face and my neck. The results have been incredible. She’s so sweet, kind, and genuine. You can feel that she truly cares and has a beautiful soul. Heather also works with BHRT and my husband sees her for his hormone care, which speaks volume about the depth of knowledge and trust within this team. What I love most is that everybody communicates and collaborates together always working in the best interest of the patient. Jillian is like the chemist of the team. She’s incredible with her peptides, GLP -1s, vitamins and everything in between. When I decided to start GLP-1s again, Jillian guided me through that phase, And she played a huge role in helping me lose that last 25 to 30 pounds. She is knowledgeable, supportive, and truly invested in your success. Every single person at Larimar Med genuinely cares. Everyone works together as a team with one shared goal improving your overall optimal health. In a day and age, when it’s hard to know who to trust, this place is truly special. I am so grateful I found Larimar Med that I’ve now sent my whole family to Dr. Fitz and her team. If you’re lucky enough to find this place, you’ll be blessed. I highly, highly recommend.

Dr Fitz has been my doctor for two years. She taught me how to heal my body from the inside! Her approach to functional medicine/hormone therapy has been life changing for me. I’m so grateful for her expertise in helping me feel the best I have in years!

Dr. Lauren Fitzgerald is an absolute gem in the world of hormone health. As a fellow WorldLink Medical-trained provider, I had the privilege of not only being her patient but also learning from her as a mentor. Over the past year, she helped optimize my hormones in a way that truly transformed my energy, mood, and overall well-being. What sets Dr. Fitzgerald apart is her deep clinical knowledge paired with a compassionate, empowering approach. She doesn’t just treat symptoms, she educates, supports, and guides you with clarity and confidence. Her mentorship has impacted both my health and my career. Her team is equally incredible, warm, responsive, and truly patient-centered. From start to finish, I felt supported and seen. It’s rare to find a practice that’s this well-run and heart-centered. If you’re looking for a provider who truly gets it, someone who listens, investigates, and helps you feel like yourself again, Dr. Fitzgerald is the one. I’m so grateful for her care and expertise.
