"I came to Dr. Tangchitnob with concerns on my acne. I am 24 years old and for years I've always been self conscious on how I've looked and how bad my acne scars are. Dr. Tangchitnob really took the time to address all my concerns with me and guided me through what steps we can take to get me where I want to be. My first procedure done with Dr. Edward Tangchitnob was the vampire facial micro-needling with PRP to help with my acne and acne scars. I was nervous that it would hurt and I would feel everything but the pain for me was pretty bearable just felt like little pokes here and there around my face. Dr. Tangchitnob and his team made sure I was comfortable each step of the way. My skin felt clean and flawless after. I was left with some bruising and redness for a couple days which is completely normal due to the PRP and healing process. Second procedure I've had done was injections/fillers for chin enhancement to create more of a shape and into cheek bones to create more volume, contour my face and rejuvenate. I was extremely excited right after to want to do lip fillers since I knew the procedures were painless, my top lip has always been thin and smaller then my bottom lip so I asked Dr. Tangchitnob to work his magic to filling them in with some volume to get a plumper look. I've loved my results that I can't wait to come back in and continue my treatment with Dr. Tangchitnob. I have already recommended him to my mom and many of my friends and would highly recommend him to anyone who is seeking guidance and a change in there life."



"I have always been a bit self conscious of my lips, they are very thin and lipstick never looked quite right on me. So I decided to see Dr. Tangchitnob to get the lips I've always wanted and boy I could not be happier with my results! They are still natural looking just a little fuller and now I am able to wear lipstick like everyone else.  Dr. Tangchitnob took the time to address my concerns, and we decided to add a little filler to my cheekbone to help with my contouring and to give my face a refreshed look. The process was painless and he made sure I was comfortable every step of the way!  I would highly recommend him to everyone."



"Dr. Edward Tangchitnob has been my Dr. for a year now and he's been a blessing since the day I walked through the door. He diagnosed me with PCOS and put me on a treatment of which I saw results within a month. 8 months after my first visit I unfortunately developed a cyst in my stomach that grew around my bowels causing severe pain. Dr. Edward was able to remove the cyst along with a GI through robotic surgery. I had a successful surgery felt no pain after I woke up and still feel no pain."



"I would definitely recommend coming here! Every time I come, the staff makes me feel welcomed and comfortable. The girls at the front are always willing to answer any questions I have and never make me feel like a bother. The wait can be long at times, but when Either doctor comes in, I never feel rushed which makes the wait worth it. If you are looking for an great OBGYN I would suggest coming here."



"I absolutely love Dr. Dumrong and his staff. I feel like I get the absolute best care when I visit. He delivered my daughter and I could not have wished for a better birth experience. He genuinely cares about his patients."
