DCVerified patient

Seeing Isaac as a dietitian was a great decision. He was very easy to talk to, and appreciated my honesty and bluntness. He listened to my concerns, and offered realistic solutions and advice. I know my body and some of what works for me (and what probably doesn’t). I know I don’t always make the best choices with my diet. But he never judged me for that. He was professional and helpful during our conversation—so much so, that it felt like I was talking to a friend or coworker. I highly recommend him as a dietitian.

Isaac is a great clinician. Personable and understanding, his approach to diets is small meaningful changes to better for choices. He takes into account his clients' living situation and conditions to tailor the best approach to reach attainable goals and remembers the little details over sessions making his bedside manner more akin to a foodie friend than a doctor treating yet another patient.
