About Jenna

Hi! I’m Jenna Delfino, a Registered Dietitian with over 5 years of experience supporting people on their journey to better health through personalized and practical nutrition care. I’m especially passionate about women’s health, helping clients balance their hormones, improve gut health, manage their weight, and navigate pre- and postnatal nutrition. I’ve worked with many women managing a range of conditions, including PCOS, IBS, GERD, prediabetes, type 2 diabetes, gestational diabetes, postpartum recovery, cardiovascular health and more. I also support those dealing with food intolerances, autoimmune conditions, and other digestive disorders. As a mom myself, I understand how challenging it can be to focus on your health while balancing the demands of family, work, and everyday life. My goal is to help you create sustainable, realistic changes that fit your lifestyle and make you feel your best without added stress.

Approach to care

My approach is all about building sustainable habits, not following strict diets or chasing quick fixes. I believe consistency over time is what drives real, lasting results. I’ll meet you where you’re at and help you create realistic strategies that feel manageable and rewarding for your lifestyle. I take time to explain the “why” behind every recommendation, so you feel informed, confident, and in control of your health decisions. My counseling style is supportive, down-to-earth, and flexible. I’m here to be your guide and your support system, helping you stay focused and motivated without guilt or pressure. Whether we’re working on gut health, hormone balance, weight management, blood sugar control, or chronic disease prevention, I’ll tailor your care to your unique needs and goals.

Your first session with Jenna

Our first session is all about understanding your full health story. We’ll dive into your medical history, lifestyle, eating habits, symptoms, stress, sleep, and what you’re hoping to achieve. I want to get a clear picture of what’s going on in your body and your life so we can build a plan that makes sense for you. By the end of the session, we’ll set small, realistic goals that feel doable right now. These goals will give you a clear direction between sessions. In our follow-ups, we’ll reassess, adjust, and build on your progress making sure you stay on track and continue moving toward your long-term health goals. You’ll leave feeling heard, supported, and with a personalized action plan you can start putting into practice right away.

Hobbies

When I’m not working, I love spending time with my friends and family. I’m a mom to two beautiful, energetic little girls who fill our home with fun and laughter. I enjoy anything active—whether it’s going for a hike with my golden retriever, Thor, strength training, Pilates, or taking daily walks. I also love cooking, experimenting with new recipes, and trying delicious food at new restaurants. And when I get a quiet moment, there’s nothing better than relaxing with a good show.
