Medical Interests: Patrick has a strong interest in promoting wellness and disease prevention, as well as treating patients through the entire spectrum of illness to wellness. In addition to traditional medical services, Patrick is excited to offer functional medicine services such as peptide therapy, IV infusion and regenerative products (stem cell, exosome, PRP) to address pain, sleep, mood disorders, inflammatory conditions and weight management. We also offer entire functional medicine programs incorporating medical weight loss, bio-identical hormone replacement, body composition optimization, nutrition counseling and sleep evaluation.

Functional medicine is ideal for patients who are willing to make an investment in themselves to pursue wellness by optimizing the five pillars of health: Diet, Sleep, Activity, Nutrition and Hormones. A typical program lasts three months and involves functional lab studies, dietary counseling, medication management, exercise evaluation, and hormone optimization if needed. Patients typically move better, feel better, use fewer or no prescription medications, and have a greater sense of wellness. Incorporating aesthetics into a functional medicine program is a great way to look as well as you feel! We can add services such as the PRP (vampire) facial to any program.

Personal Interests: Spending time with family, golfing, biking, cooking and traveling.
